 Lived up to expectations!
By , Connecticut, August 3, 2014

The quality and functionality is terrific. Packed enough for a two week tour of France. It was also a plus when other travelers commented about it and asked about the brand. I am one happy camper with all my Redoxx purchases (e.g., sky train, C rucksack, and rigger wallets - and too numerous to mention accessories).
 Backpacking for grown-ups
By , Washington, DC, August 2, 2014

My wife and I are well past the age where we might backpack through Europe. But on a three-week trip this summer, we really did not want to check a bag and my Air Boss was not going to be big enough for both of us. We bought a Sky Train for the trip and it didn't let us down.

Just like the Air Boss, it fit in the overhead bin of the regional jet we took for one leg. Just like the Air Boss, it is exceedingly well-made. Just like the Air Boss, it has compartments that hold more than you think they should.

Compared to the Air Boss, the backpack straps are a real plus when you've got a long haul to get to Passport Control after you land. I think the Air Boss holds more, but it got pretty heavy on my shoulder on long walks to connecting gates.

Compared to "normal" luggage, the only downside of Red Oxx is that you have to do the bundle packing method, which gets a little old when you're changing hotels a lot. But for us, the much bigger capacity, the fact that it fits in the smallest overhead, and the fact that they build things to a quality other manufacturers can't even see--all of those make the bundling just a minor annoyance.
 Sky Train
By , Lancaster PA, July 29, 2014

I've been looking for a carry-0n that also had backpack straps for many years. Finally I stumbled upon Red Oxx and your Sky Train. Great bag. I also ordered a couple Lil Roy's and a the Nomad Shave Kit. Your quality is top notch.
 Really good
By , Brazil, July 17, 2014

Just came back from a 20-day trip around Europe. I took 10 t-shirts, 3 bermuda shorts, 10 pairs of socks and 10 of briefs, one pair of sneakers and one of flip-flops, all fit well inside.

This is a really good bag: resistant, great quality, versatile, beautiful, and it packs up a lot. Actually, be aware that it might become non-cabin luggage if you overpack it. Overall I'm really happy, hoping to have it beside me for the rest of my travel life!
 Lightweight travel must
By , San Diego, June 27, 2014

I purchased a Red Oxx Sky Train bag/pack in anticipation of a two-week trip to Europe this spring. I was intrigued by the bag's good reviews online, including light weight packing zealots, which inexplicably are everywhere. We had traveled with an assortment of TravelPro roller bags in the past, which were fine, if you had a flat street without cobblestones or a floor to drag the bag through. My wife was sold on them, as she is a flight attendant and travels for a living; and, those bags make traverse through hotels and airports a breeze. But, I wanted to push the limits and give myself more flexibility.

The bag, although appearing small, will allow you to pack a ton of stuff, especially if you use some of the drape and fold methods suggested by the light travel zealots. I found I had a lot of space left after packing my electronics, three pairs of everything, and an extra pair of shoes. Predictably, my wife saw an opportunty and stuffed her overflow in my bag. So much for light travel.

Carrying the bag, instead of rolling, proved to be an adjustment, especially with security checks every ten feet. The back pack straps were a bit of a hassle, but proved their worth walking around Belgium and the Netherlands, especially on trains, in places my wife's roller would not go. But, it is not a classic "backpack" and would not be appropriate for any camping.

Travel, while a life's dream and passion, does take work; and, this bag gave me more flexibility and ease than any TravelPro.

I stongly recommend an adventorous traveler that likes to strike out without the albatross of a roller to get one of these.
 just another great review
By , Denver, June 19, 2014

Does this bag really need another glowing review? Probably not, but that's what it's going to get. I got to try it out when a friend got one and fell in love and ordered it for myself the next day. I used to be a wheeled carry-on type of girl but that resulted in gate checking 8/10 times. This bag looks small enough for flight attendants to allow you on even when they're gate checking others and the bag fits just as much as my max regulation size wheeled carry on did. The backpack straps are priceless. I can carry it through airports without getting tired. Workmanship is great, design is great. Looks most awesome in the safari color
 Best luggage ever!
By , Minnetonka, MN, June 12, 2014

The sky train is awesome. I was afraid that it's backpack straps would be too flimsy to really work well carrying heavy bags, but they are really built well, and padded nicely. We covered a lot of ground with these on our backs, switched to the shoulder straps when we were waiting to board planes, and were comfortable the whole time. They are easy to pack, and they fit well in the overhead bins, even when they're stuffed. I can't imagine a better bag.
By , Raleigh NC USA, June 6, 2014

I had the opportunity to test out my Skytrain both in the Sky and on a Train. I had a very tight schedule involving flights, a 5 hour train ride, rental cars and taxis in 5 cities and 3 states. I had to get in and out of vehicles quickly and take steps and go places not necessarily friendly to pulling wheeled luggage. This is exactly the type of trip the Skytrain was designed for and it worked flawlessly. I used the backpack straps. (hint; to keep the sternum straps from slipping down when not in use just buckle them together) I used the shoulder strap when bringing it into a client meeting and I used the handles to put it in various overhead bins. I was one of the only people on one of my flights home (very small commuter jet) that did not get my carry on tagged for gate check.

On another flight I heard one of the flight attendents at the plane entrance say to the other; "anything you see with wheels, tag it! I don't care how small it is." When you breeze through with your Skytrain on your back you then seem to notice more how overly dependent people are for their wheeled luggage and how it seems to take a lot of their time and attention. The build quality is over engineered to the point that you do not worry at all about it.

The thought of design reveals itself much more when you actually travel with it. You then notice little things (such as: the zippers are automatically locked unless pulled by the monkey fist zip pulls- try to move them with your finger without pulling up-they won't move) that show how much thought has gone into the design that looks deceptively simple.
By , Australia, May 15, 2014

I'm a fan of sub-40 litre carry-on bags. I have several and when packed right they are rarely challenged by airline staff. The Sky Train actually holds more than my other bags but its design and shape are deceptive in that the bag holds far more but still looks small. Very clever design and the back-pack straps are icing on the cake.
 Red Oxx on European 3 week tour
By , Maryland, April 26, 2014

Had a great experience with the Red Oxx bag. Used it for a 3 week business and pleasure trip through Europe. The bag was able to accommodate nicely all of my items. I set up to use the bag pack straps. I used them once but my husband ended up carrying the bag most of the time so we used the handle section. I felt very
 Perfect bag
By , Ireland, April 24, 2014

Great bag: rock solid & dependable, really well designed. Shoulder strap is great too - it just won't come off. the bag was also issued much faster than the 30 day turnaround.
 Oh yeah!
By , Florida, March 20, 2014

Construction is impeccable, didn't see any flaws or stray and excessive material waste within the bag. Big zippers, solid stitching along with the heavy duty clear tubing surrounding both grab handles are "choice". Material selection appears to be able to withstand a good number of road years of abuse that I'm going to hand it. The only "personal improvement" recommendation that I have would be to add another "d-clip" sewn into the other side of the top handle. That way one could use the carry strap with the sky train orientated in a "portrait" carrying style manor. Needing to order another might ask Redoxx if that's "do-able" even as a "one-off" option. Cheers.
 Great bag
By , Dallas, Tx, March 13, 2014

This is great bag overall. Loved the space, compartments and how it is great for travel even on smaller planes. The only reason for the 4 star rating is that the shoulder strap can be rather uncomfortable when the bag is fully loaded.
 Solid and Awesome
By , , March 6, 2014

I normally don't write reviews, but I also normally don't experience exceptional products. I just finished an ambitious 5-night business trip with my Sky Train and it delivered the good. Literally.
 Great Bag!
By , Walton, Kansas, February 27, 2014

I have used this bag (so far!) for long weekend trips, and am amazed at how much I can pack! I use eBag packing cubes and have no trouble getting everything packed in.

I have yet not tried the back pack feature, but expect this will come in handy for international travel where bags with wheels cannot be successfully used. I love the soft sides and the two compartment design.

Trying harder to pack "smart" - Hope to use this bag as my sole bag for a two week trip to Guatemala this summer! Wish me luck!
 Savvy Travelers Must Have This Bag!
By , San Francisco Bay Area, January 16, 2014

After becoming a one bag convert, I decided Sky Train was the right bag for me, bought it and practiced packing & unpacking it via the bundle technique along with packing cubes. My next trip was a 10 day vacation to the east coast. I tested Sky Train by deliberately over packing and it passed with fantastic marks. It amazes me to this day how many travelers skirt the carry on rules. My overhead bin was almost full (in first class no less!) by the time I boarded. Sky Train's soft shell material allowed me to wiggle it into the overhead with no worries.

During my trip I efficiently unpacked & packed in 2 hotels and a friend's house. Traveling with one bag allowed me some souvenir liberties that I was able to carry home in a separate plastic bag. Sky Train's backpack flexibility came in super handy when my flight home was delayed for several hours. I comfortably navigated the airport terminals with minimal hassle. Some minor suggestions: like other reviewers mentioned, a removable waist strap and wider & slightly better padded backpack straps would enhance carrying comfort and stability. Other than that, Red Oxx has themselves a fantastic mainstay for their bag line up. I've already donated all of my other luggage pieces and am a staunch net promoter of Sky Train. Cheers!
 A Superb Bag
By , Calgary, AB, January 16, 2014

I've only used the Skytrain on a few trips, but it is surprisingly capacious. The outward appearance belies the overall capacity of this well-constructed, highly durable bag. As a long time Tumi customer, I can attest that the quality of the Skytrain is on par, if not better, for half the price. As long as you're okay with luggage sans wheels, I would highly recommend this bag for both business and leisure travel. The only caution is that the bag is easily over-packed, and even with the optional backpack straps, can prove to be a heavy load. However, if you're willing to pack smart, this bag is a must have.
 must have for international travel
By , Weatherford tx, January 6, 2014

I purchased this bag for a month long trip in Europe that consisted of 10 flights. This bag saved me many times. The size is just perfect for the budget airlines restrictions. It was small enough to met requirements but large enough to fit a weeks worth of clothes. My other friends had to check their bags. This bag is worth the money just to save on checked bags.
 The best Carry On Bag Ever Made!
By , Albuquerque, January 6, 2014

This is the best carry on bag ever made. It is great for air travel. It's so well designed that I can forgo checking a bag in instances when I used check one. It saves time and checked bag fees and I don't have to worry about the airlines losing my luggage. One of the best pieces of luggage I have ever owned. I love it.
 Red Ox Sky Train
By , Paris, France, December 27, 2013

I recently purchased a Sky Train for my brother after reading the recommendation made by Doug Dyment at My brother is a musician who travels continuously, and has found the Sky Train exceedingly useful. So I then purchased one for myself. I rarely write product reviews, but this is an exceptionally well made and well-thought-through product which is a pleasure and a great help to travel with. Congratulations and thank you.

Frequently Asked Questions

Is the Sky Train carry-on legal?
Yes, the Sky Train is designed to be carry-on legal on continental flights and most international ones as well.
What's the best way to pack the Sky Train?
We recommend using our Red Oxx Packing Cubes. They're designed to work with the dimensions of the Sky Train. You can build your own personal custom packing cube kit. Not into cubes? Try the bundle packing method. Watch the packing video under the Videos tab or download the Sky Train Packing Diagram.
What's the difference between the Air Boss and the Sky Train?
There are two principle differences between the Air Boss and the Sky Train: The Sky Train has retractable backpack straps and opens flat lengthwise and has two packing compartments whereas the Air Boss opens flat like a book with three compartments and is carried with the Claw shoulder strap. The Sky Train was also developed with smaller stature travelers in mind.
Will the Sky Train Carry-on fit under the seat in front of me?
Cramming the Sky Train under the seat is not recommended.

Will the Eagle Creek packing cubes fit?
Why bother with cheap imported packing cubes when you can build your own Red Oxx Packing Cubes Custom Kit designed to work in conjunction with your Sky Trian. Or try our Nomad Shave Kit, Lil Roy Gadget Bag as packing cubes. You can color co-ordinate them to your preference and they come with useful carry handles. The Tri-fold Toiletry bag is also a brilliant shave kit or makeup organizer due to its three individual zippered mesh pockets and unique fold open flat hanging design.

How many pounds will the Sky Train weigh when packed?
It depends on what you pack. A typical 3-5 day load will weigh about 20-25 pounds.
How many days travel can I fit in the Sky Train?
Most folks can get about 3-5 days with a typical load. Some adventurous types have been able to pack from a week to 10 days! It all depends on how you pack and what you pack.
Where do I pack the laptop?
You can use the back compartment. We recommend that you use a padded neoprene sleeve to secure your laptop.
What's the best way to pack footwear?
Sole to sole to minimize the dirt and placed in either compartment. We recommend placing your shoes in a plastic bag. Or try a Nomad or Meerkat Packing Tube.
Can I change the logo color?
Sure. Simply order your favorite color Logo Patch and sew it on yourself. Red Oxx cannot change the patch colors for you.
Can I order a bag without the logo?
Logo Patches are centered using a hole punch. If you remove the patch, there will be a hole in the bag that could cause a snag. Red Oxx cannot build a bag without a logo as this would disrupt the efficiency of the production line. Feel free to use a permanent marker to color the patches.
Is there a way to securely lock my bag?
Sure, you can use any TSA approved bag lock or try our Cable Lock for a simple, semi-secure solution. Watch this video where CEO Jim Markel demonstrates how you can use the cable that comes with the product Dog Tag price tag to secure your bag. Keep in mind, any determined thief can still cut open a soft sided bag with a sharp knife.
Are there any interior pockets?
The Sky Train Hybrid bag has two generous internal compartments and one small internal zippered pocket.
My zipper broke. The teeth have separated. Do I send it in for warranty repair?
No need for warranty repair, try and fix it yourself. Check out this video where CEO Jim Markel shows how easy it is to do it yourself.
Why doesn't the Sky Train come with a waist strap?
The bag was not designed to operate with a waist strap. However, you can use a pair of Luggage Compression Straps to cinch down the bag from the outside. Wrap one strap around the top, about 4-6 inches down, and the second strap further down, about 4-6 inches from the bottom. The top strap, if cinched tighter than the bottom strap, will pull the pack closer to your upper body, relieving excessive weight from the pack on your hips.

Another option is to take a belt, any belt will do, and thread it through the holes in the smuggler's pocket at the base of the bag where the backpack straps attach to the bag. While not a very comfortable way to travel, using a belt this way can also relieve some weight off the hips. The best solution however, is to focus on traveling light and not over pack your Sky Train. Use the internal cinch straps to hold your belongings in place and minimize wrinkles.

Can you ship USPS?
Yes, Red Oxx will ship USPS upon request. Simply state, "Please ship USPS" in the cart comments during checkout and we will adjust your billing accordingly.
“I just say no to checked bag fees.”

Carry-on! On your back.

Our Red Oxx travelers called it awesome! Imagine, a convertible hybrid backpack and carry-on travel bag in one.

Your idea of carry-on perfection? The Sky Train meets your desire for hands-free, easy-on, easy-off boarding of planes or trains. Specially designed for the leisure traveler going to Europe or beyond. Keeps you moving. No waiting for late or lost luggage--it's with you all the way. A bag built for mobility. Once your Sky Train is on, you're gone!

In 2007 Red Oxx teamed up again with web author and travel expert Doug Dyment of fame to develop this carry-on backpack travel bag. Doug called it the "quintessential dual-purpose bag". Think flexible-- this mobile carry-on bag can be carried five different ways:

1. Carry like a suitcase using the Euro handle on the side.
2. Vertically using the Euro handle on the top of the bag.
3. Over your shoulder like a messenger bag using the Claw Shoulder Strap.
4. Cross body, carried like a messenger bag, again using the Claw Shoulder Strap.
5. Or pull out the retractable backpack straps from the smugglers pocket and travel in hands-free comfort.

The grab loop Euro handles on the sides also help stowing the bag in the overhead bin. Fits continental airline luggage boarding size restriction box and most international ones, too. Includes an adjustable and removeable sternum chest strap.

The Sky Train Carry-on features two main interior compartments and one full-length outside zippered flat pocket. The main compartment tie downs cinch down to the closed cell Volara foam, securing your clothing. These tie downs help keep your slacks and dress shirts wrinkle-free until you can hang them up in the hotel. Easily holds three pairs of slacks and three blouses with room leftover for a light jacket.

The secondary compartment has a foam stay and a small pocket for stashing personal items (9" x 12") and is spacious enough to hold your Toiletries, shoes, or workout gear... The rigid sewn-in Volara foam padding protects your belongings, but is still flexible enough to shove into a cramped overhead bin.

Follow this link to learn Doug's bundle wrapping technique. Fit more in your Sky Train airline carry-on bag. Thanks to, here's a handy printable PDF Sky Train Packing Diagram. It covers how to "bundle wrap" for the Sky Train, your ideal backpack hybrid convertible travel bag. Or watch the packing video in the videos tab where professional travel guide Kasey Austin of Austin Adventures demonstrates some of her awesome packing tips.

Don't like bundle wrapping? Build you own custom Red Oxx Packing Cubes Kit. Our made in Montana cubes are designed to work in conjunction with the Sky Train. Ladies, check out the Meerkat Packing Tube, a tube cube sized just right for hair care products.


Our customers like to define our gear as "built like a tank". While obviously you're not going to be toting around bags that weigh 50 tons and have three inches of armor plate, still the comparison is valid. For a carry-on bag, Sky Trains are built tough. Starting with the most durable soft textile material available, 1000 weight CORDURA® Brand Nylon, we use super strong UV resistant thread that is double stitched into every seam. Rugged, reliable and tough.

Places where two separate pieces of fabric are stitched together are then bound, that is, we take a long piece of one inch wide nylon webbing and fold it over the edges of the two pieces and stitch them together, this creates a strong seam, or binding, that prevents the pieces from unraveling on the inside of the bag, or gives it a clean finished look if on the outside of the bag.

In addition, each exposed fabric edge, such as on a pocket flap, is also bound using a thicker binding material. Inside edges typically receive a thinner nylon webbing, whereas outside corner edges that are exposed to wear will have a thicker nylon binding. All of our binding material is vertically woven to prevent fraying, peeling or splitting that you may commonly see in competitors bags that brag of "binding" their edges.

Each stress point, such as where the handles attach to the bag, is double box stitched - which is where we get the "double XX" in our name, Red OXX; a stitching practice we adapted from our time as parachute riggers.

The reason Red Oxx uses the largest practical zipper we can find, the #10 YKK VISLON® zipper, is that they are easily repairable, even in the field; they will hold their place, that is, they "lock"; they are difficult to penetrate, thereby increasing the security of your belongings; they function smoothly in inclement weather and they can be yanked from a variety of angles without losing teeth or becoming separated.

Red Oxx has occasionally been accused of "overdoing" our hardware. But once you've had a cheap piece of imported plastic hardware break in the middle of a busy intersection, airport or other inconvenient locale dumping your precious belongings all over the ground for all the world to see (and steal), having a heavy-duty nickel-plated or stainless steel D ring or attachment swivel that weighs just a little more, or might make a little noise, is a travel companion's confidence builder and peace of mind maker. After all, you want to enjoy your journey as best you can. Traveling with a Sky Train Convertible Backpack bag, you'll know it won't bust apart and break you down.
