 The ultimate travel bag!
By , Hibbing, MN, November 28, 2011

I love this bag! I can easily carry it by the handles when going through security or boarding, it stores very nicely in the overhead or under the seat, and the backpack straps are awesome! I was able to get fast food with it on my back, not having to drag around anything on wheels. Extremely rugged, just the right size, and feature-rich, this is the best bag I have ever seen!
By , Australia, November 25, 2011

This is the first time I've travelled with just carry on. The other reviews sum up its features perfectly. I can't believe all the holidays I've taken lugging an enormous, ungainly suitcase. Never again. I have spent a HUGE amount on suitcases that were badly damaged after a few trips. This bag is well worth the money. Excellent quality. It carried enough for 3 weeks around France (dress and casual clothes - I did not Rough It), and made travelling a breeze. The straps made it easy to pop on my back when walking any distance (I'm nearly 50, and easily carried the 9kgs I'd packed into this bag), and the quality and construction meant I could put my feet up on it when reading whilst waiting at the airport. Being only 5'2" it also comes in handy to put my feet on when sitting in the plane. Now that I'm back home, I tuck the straps away inside it, and use it for weekends away strapped to a motorcycle. (Be prepared for bemused airline check-in staff who cannot understand that you only have hand luggage when flying from Australia to Europe - there are double-takes looking over the counter to check that there really is No Suitcase)
 Best Carryon ever
By , Santa Cruz, Ca, November 7, 2011

I travel a lot and have been all over the Earth. I try to never check bags unless on a military hop. This is by far the best product I have ever used and I have tried many from..Patagonia, Swiss army, Eagle creek, Tumi, Filson and North face. Your Carryon is well engineered and worth the price. I have always been willing to pay for quality items that out last the cheaper stuff.
 Great bag for multi-night trips
By , York, UK, November 7, 2011

I bought this bag for frequent 1 / 2 night business trips - too long for just a laptop bag & too short for a big wheelie case. I am constantly on & off trains, tubes and taxis so a bag I can carry is vital as are separate compartments for #1 computer / business and #2 clothing / personal - I can't open up a one-section bag in client offices ...

The SkyTrain may be a little too big for my needs, I now realise how people say they can live for a week out of it! However the quality is superb, the fit & finish and materials used are superb. The danger is in over-packing it, there is a lot of capacity relative to the outside dimensions.

It is quite unstructured & soft-sided, I guess to aid with the practicality, but looks very smart too - I chose green panels to avoid joining the endless lines of boring black bags.

Only just got it, but feels like it'll last forever. Very pleased.
 Plain and Simple
By , Boulder, Colorado, November 3, 2011

I am really enjoying the bag; I like simple and rugged equipment. The hardware is the best. I had a fancier bag but could never figure out how best to use all the pockets and compartments, and would misplace things. Now I use some packing cubes and the Sky Train. My only gripe would be the handles, I would prefer some padded and sewn up types.
 One Bag to Rule them All
By , Maine, October 31, 2011

I purchased the Sky Train in time for a 3-week trip to Switzerland, Croatia, and Italy. This trip posed a challenge for one-bag packing, since we needed clothing and gear for high-elevation hiking, tropical weather and beaches, and nicer attire for evenings in Rome. With careful selection, I managed to fit a complete range of clothes, technical gear, maps, and books in the bag, about 18 pounds in all. We traveled entirely on foot or via public transportation, including trains, buses, planes, ferries, and water taxis.

The Sky Train performed well in terms of holding everything I needed and in ease of transport. I was amazed at the volume capacity, rugged design, and comfort when carrying it. Since then, I've used it for extensive business travel and found it perfect for week-long trips, accomodating business professional attire and laptop and charging gear. A few suggestions for improvement would be: 1) adding an attached leash w/a snap clip inside the zipper pouch, to securely hold a set of keys; and 2) reducing the weight of the stainless steel shoulder strap snaps.
 Extremely impressed so far
By , Boston area, October 31, 2011

I've only used this bag once so far - on a 2 week trip to visit family. The hardware construction is (as everyone else indicated previously) insanely high quality. Even the shoulder straps (which looked a little skinny in the photo) have a nice surface texturing and padding that allowed me to carry a lot of mass without pain.

The small number of compartments was not a barrier to logically arranging the contents of the bag, either.

I used the shoulder strap part of the time and the rubber pad acts like it is welded to your shoulder. It simply will not slip off.

Looking forward to using it on my next trip and (based on the construction) a very long time to come.
 2weeks in Italy
By , Indiana, October 31, 2011

I am a 61 year old female. I packed for 2 weeks and weighed in at 20#. This was fine until I made the long treks through airports in London and Madrid. The sky train holds everything so I took everything. I love my bag and plan more trips with less weight. At my age I like to buy the best so I don't have to replace it later. Thank you red oxx for manufacturing here at home and making a quality product on top of my son wants one.
 Almost perfect
By , Alaska, October 30, 2011

I rated this bag only 4 stars since my wife did not feel completely comfortable using it with the back pack straps. Like other comments, she really wished it had the hip strap to help support the load. She is 5'4" and it was loaded pretty full. I'm 6'4" and had no problem using it, although I did not carry it long.

The quality is outstanding and it did its job. I bought the Air-Boss since I travel more for business. We did a 2 week vacation all with carry on. Thanks to the onebag website for the recommendations.
 Another amazing product!
By , Toronto, October 21, 2011

I bought this bag after a couple recommendations from members of a watch forum I visit.

Everything I've read about this bag is accurate - built like a tank and holds loads of gear.

I employed the one-bag approach during my 20 day stay in China, and this bag (along with a Gator) performed perfectly. Highly recommended!
 Convenience like no other
By , Brisbane Australia, October 12, 2011

This bag is very surprising, it swallowed my gear for a 10 day resort trip without blinking and with room for more.

Sitting on the floor of my office it drew lots of comments many scoffing that it fitted the carry on guidelines but all impressed with the design. At the airport it effortlessly fitted the size gauge without being sat on. Impressed.

The pack straps are excellent and so convenient I used them at every opportunity, unlike a large travel pack I own where the harness is such a pain to stow I struggled with rather than use it. They adjust easily and feel very solid.

Great design. Buy one
 Good Enough
By , UTAH, October 6, 2011

Straps are a little less than an OCD guy like me might hope for, but, good enough. Holds a lot of stuff. RED OXX could do better by adding a few velcro patches and some small exterior/interior pouches to accommodate some of the gear I travel with. Overall, Im glad I bought. RED OXX, like our country, has its problems, but it's the best gig in town. Thanks RED OXX. I'll keep buyin' for sure.
 Everything and More
By , California, October 2, 2011

The Sky Train was a perfect choice for me for my recent trip to New York. Eight days with some practical packing and what a breeze. I chose to use the carry handles and not backpack it and it was quite comfortable in my hand and easy to carry long distances. I noticed a lot of glances at my pack as I walked around. It has a nice rugged, well-built look to it which is true. No need to "baby" this pack. My relatives could not believe I fit it all in that "little pack" as they called it but I sure did and I look forward to my next trip. Great product. Thanks.
By , Apex, NC, September 19, 2011

WOW! That is how I sum up the SKY TRAIN (black).

Searched and looked for a carry-on bag on or around Aug 22, 2011. Found RED OXX online and drew my attention based on the reviews, Lifetime warranty and made in America. I was down to a week before I left and wanted a bag I could carry-on, last 5 + days and, last me for a very long time.

I was worried that the bag wouldn't be sent in time so, I sent them an email asking some basic questions. Will this is where they pulled me in!!!!

The Customer Service was the best I have seen in years!!! The bag I wanted was on backorder. This meant after receiving an email from them that this bag would be finished Aug 23rd or Aug 24th (the day I email or the next!!) in there next batch from the production floor.

REDD OXX re-assured me that they would get the bag to me before, I left. Will they made that happen in plenty of time. Received it on Friday Aug 23rd. in Apex, NC. Thank You REDD OXX!!

What's funny is a previous post on the cat hair sticking on the bag!! I had the same issue. I believe, this is my problem not REDD OXX's. The bag worked out great on my trip!!
 Great all-around travel bag
By , based in Texas, travel the world, September 15, 2011

I purchased this bag after much research, and am pleased with my choice. After a week-long photo shoot in Seattle, I still managed to put all my Theo's chocolate purchases, four books, my laptop, 4 furniture wheels (don't ask!), my camera equipment, and my clothing in the bag. I have found the front compartment perfect for my laptop (easy in and out for security), and I keep a small backpack in the front compartment for carrying my photo equipment during shoots. Even with this load, I was able to fit the bag into the overhead compartment with ease, and then quickly deploy the shoulder straps to exit the boarding area before most people had their luggage handles extended and personal items secured to the tops of their bags. Getting through the airports was a breeze, and my transportation could not believe it was the only bag I required! This bag reminds me of Dr. Who's spaceship: larger on the inside than on the outside. I am packed to leave for Bonaire tomorrow!
 well built
By , Post Falls, ID, September 8, 2011

Used this bag for a seven week trip to Europe. Stores lots of items however becomes heavy. Zipper difficult at corners. Purchased because it did not have wheels however wished I had a wheeled bag for this trip
 Deceptively Roomy!
By , Seattle, Washington, September 1, 2011

It is fabulous and can fit way more than I imagined possible. Built so well and easy to carry. I am a happy girl.
 Surprised & Happy
By , Vegas, August 27, 2011

I was surprised at how much I can fit in the bag! I'm a notorious over packer so when I got the bag in the mail, I nearly hyperventilated. I tried it out and was surprised how much fits! I had no problem packing a dress, dressy shoes, 2 pants, and 4 tops in plus toiletries and my netbook with plugs. It's easy to get in overhead on the plane (I'm only 5'1). Really easy to carry on your back!
 Great choice!
By , Arkansas, USA, August 26, 2011

I ordered by Sky Train about a month and a half ago. I've done one week in NYC and two weeks in Hong Kong/China. Both trips were just the Sky Train and a handbag and it worked wonderfully. I did not have to gate check the bag on commuter planes and passing by baggage claim/recheck when re-entering the US was pretty amazing!

My only comment, and I won't even call it a complaint, is that the outside fabric is very pet hair. I ordered a black bag and even if the cats didn't want to sleep on it (and they do), I have to be careful or it will pull whatever hair is on the surface it is being packed on. Again, not a complaint, I just clean off the hair the night before I leave and put my packed bag out of the cats' reach and all is fine.

Overall this is a great bag, the back-pack straps are great for trekking through the airport. I don't care to carry using the shoulder strap because I am rather petite, but it is definitely comfortable for shorter distances.

I'll be back in Asia for 2+ weeks in a month and can't wait to take my Sky Train with me!

By , El Paso, Tx, August 21, 2011

Excellent product. I was able to easily access all compartments to go through all the airport security and also to get anything out I needed. I packed everything I needed for a week trip in this bag plus one extra for my laptop. Highly Recommended.

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.
