Our Red Oxx Travel Testers call it awesome! Imagine, a hybrid backpack and carry 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 lost luggage--it's with you all the way. 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. Think flexible-- this bag can be carried three different ways:

1. Carry like a suitcase using the Euro handle.
2. Over your shoulder like a messenger bag.
3. Or pull out the retractable backpack straps from the smugglers pocket and travel in hands-free comfort.

Grab loops on the sides help make stowing the bag in the overhead bin a snap. Fits the luggage boarding size restriction box.

The Sky Train 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") 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.

Due to high demand, we encourage you to place your order now to get your Sky Train on our production schedule. It will then be delivered in under 30 days. Like retirement, it's worth the wait.

Dimensions: 20"L x 9"W x 13"H

 Bag Full of Awesome
By Randall, Omaha, Nebraska, August 9, 2012

I haven't been on a trip involving air travel in quite some time. For all the obvious reasons, I don't care for it. I've been going out of my way for quite some time to purchase quality products made right here in the USA by folks making a living wage .

So when I finally had enough coin to buy Red Oxx, I did, and nine days later, I am extremely glad I did. My clothes and personal items have never stayed so organized, and using Doug's bundle system, everything stayed fairly wrinkle free after more than a week of being packed(I didn't have the luxury of hangers and drawers on this trip).

I overpacked: 4 shirts, 2 pants, 1 belt, 3 shorts, 1 sleep short, 1 bathing suit, 2 pairs of shoes (and I bought 2 more on the trip!), toiletries, 3 socks/underwear, 1 golf jacket, 1 magazine, and 1 book.

Getting through airport security was a snap with the outer pocket being perfectly accessible, and the different handle/strap options were all utilized at different parts of the trip. And last but not least, the bag still fit under the seat in front of me while everyone else had to "valet check" their bulky "carry ons".

This bag may be the one that will serve me to the end of my days. Well done, Red Oxx.
 To Germany and back...
By Bill, Texas, August 1, 2012

I just got back from 2 weeks in Germany and absolutely loved my SkyTrain. I've had a BeanosPR5 for 5 years but my wife nabbed that for an earlier departure so I ordered a Skytrain to try the different configuration for my carry-on needs. I was able to fit a week's worth of clothes with room to spare for other travel needs. This is no easy feat as I am bigger than the average bear. The front and back compartments were just the right configuration and felt like it fit my needs even better than my beloved PR5.

The cinch straps in the back compartment seemed help swallow large cloths into a tidy bundle. They day I received my shipment an office-mate saw my SkyTrain and promptly ordered one for her husband as he has thrashed every business travel bag he's ever gotten.

2 thumbs way up, Red Oxx!
 cross country and back
By Susan W, New York state, July 30, 2012

After reading the recommendation on I bought this bag for my recent trip to Portland, OR. It consisted of three legs each way on USAir. Not wanting to give the airline that many opportunities to lose my luggage, I needed a good carry-on. I already have a wheeled bag I love, but have found it increasingly cumbersome for navigating airplane aisles and overhead bins. Not to mention the many spots where the bag has to be lifted for escalators, boarding buses, etc. I was ready to lighten my load.

Onebag describes the Skytrain as a good compromise between a business bag and a leisure bag, which I've found to be true. I don't want one wide open space for everything, nor do I need a large number of compartments which decreases actual packing space and increases weight. The Sky Train hits the sweet spot. I made an effort to pack lightly, and indeed the bag wasn't even full on the trip out. I was able to manage carrying it backpack style on the outbound trip, with two lengthy layovers. I am 60, short, and not particularly strong, so I thought I was doing pretty well!

Coming home though, I had accumulated a number of weighty purchases. I could fit them all in the bag- just barely- but the bag was so heavy I decided to check it. Sure enough, it had several scrapes and black marks. I was able to clean it pretty well in the shower! I got the saffron color, which is easy to spot. My only complaint is the weight. I agree with anonymous in Seoul, who said it's "overbuilt" with heavy hardware and beefy zippers in places they're not really needed. Also, I think a waist belt would be helpful. I look forward to using this bag on many more trips!
 Like it? I just bought a C Ruck for my daughter
By Hal Bruner, California, July 15, 2012

Lifetime guarantee, made in USA and available in a bunch of colors besides black. For my trip to Georgia, I packed 3 pairs of Levi 501's, 6 silk Hawaiian shirts, 6 sets of socks and underwear, camera, laptop, 4 DVD's, assorted cables and power supplies, and a pair of flipflops. When I got to Georgia, it was to hot and humid for anything but the Hawaiian shirts and flipflops, so I bought 6 pairs of shorts and some souvenirs. The Sky Train carried all of it easier than I did. And it easily fit in the overhead. My daughter liked it some much, it's her birthday present.
 Two words: worth it
By BT, Boston, July 12, 2012

I was inititally hesitant to spend >$250 on a travel bag, but my fears were unjustified. The bag is extremely well made, it is light, and I had no trouble fitting it into small overhead bin spaces. The warranty sealed the deal for me. But I agree with the other comments about how having such a bag forces you to bring less. But I am happier with a lighter load, and am 100% satisfied with this purchase.
 Incredible Quality
By Mike, Texas, June 30, 2012

Wow, as a gear bag junkie, I have owned and used virtually every type of backpack, travel bag, brief case out there. The quality of the Sky Train is second to none. Buying from an American manufacturer matters and this bag does not disappoint.

As for utilization, I have used it for a 10 day trip to Europe (my only bag) and it fit everything I needed. I also used for a short haul trip in an Embraer (small American Eagle aircraft - with VERY small overhead bins). I used the Sky Train for my only bag for this one (1) week trip and, WITH my computer backpack stowed inside the Sky Train, I was able to carry all of my belongings AND stow it in the overhead bin of that little plane. Wow.

The back pack straps make carrying easy and they stow away easily too. Having 2 main compartments allow for easy locking since you can gather all the zippers in one place. Note: I use the Eagle Creek double cube full size cube for my clothes and 2 of them fit - barely - side by side in the bottom compartment while fully stuffed.

My Travelpro rollaboard is officially retired now that I have this Red Oxx. Can't recommend this bag enough. Bravo to Red Oxx for representing American manufacturing so well!
 Extremely Well Built!
By Matt, Tennessee, June 21, 2012

I purchased this bag on a recommendation for a trip to Europe. Just feeling the bag - I know it will last me for my lifetime as it is so well built!
 Super Quality!
By Nicklas Bjorklund, Malmo,Sweden, June 8, 2012

I´m extremely impressed with the materials and the workmanship in the Sky Train. Only had time to try it out on one trip so far but there will be many more to come, trust me.

Only negative thing is that there is no european retailer, so the shipping and import cost added quite a bit to its price.
 Oh, what a bag!
By Wendy, Carlsbad, CA, March 31, 2012

I'm on my second trip in one week with my navy Red Oxx Sky Train, and it has delightfully lived up to my every expectation. It's lightweight, holds all my junk, and is easy to carry. On my first trip a few days ago, I left the backpack straps inside and just slung it over my shoulder in order to get accustomed to the size and weight of the bag. On my second trip, I pulled out the backpack straps and love the bag even more than I did after trip #1. I'm a firm believer in quality over quantity, and with the Red Oxx bags you get an amazing product that is still proudly made in the USA. Thank you, Red Oxx, and God bless America!
 Favorite Carry-on Bag
By JB, Colorado, March 29, 2012

I heard about this bag years ago but couldn't justify the cost. I went through several other cheaper bags that I wasn't happy with and would have saved myself money if I'd bought this in the first place.

I couldn't decide between this and the Air Boss and I'm glad I went with this. The backpack straps distribute the weight comfortably instead of contorting your back carrying it all on one shoulder. The padded straps are surprisingly comfortable even if you pack a lot.

Very well made. It'a actually more aesthetically pleasing than it looks online.
 Really Good
By Andrew, Las Vegas, March 22, 2012

I really wanted to love this bag. It has the typical awesome Red Oxx construction, and I expect it to last many years. Unfortunately I'm not sure how many of those years it will actually get used. My main issue is with the 20x9x13 size, if it were 21x8x13 like the Air Boss it would be perfect, but that extra inch in width makes all the difference. I know that sounds silly, but I've never overstuffed my Air Boss to the point where I could barely get it into the overhead bin, I have with my Sky Train. And I mean BARELY. For some this will mean something, I was in zone 2 boarding on a Delta flight and the zone 4 peeps were boarding by the time I was able to jam it in the overhead. At one point I had to defend against the dreaded gate check. I waited to be the last person off so I didn't risk injuring someone trying to get it out of the overhead.

On the plus side I love the handles. I have the Rail King Rucksack and I wish Red Oxx would wrap the grap loop on the top of the bag with the vinyl tubing. That would make my decade.

For now my search continues for the perfect convertable bag.

 best travel bag
By Bryan, NYC, March 8, 2012

What an incredible product. Very well made. Solid construction. I traveled to Chicago for 6 days, then spent a weekend in New Orleans. I needed no other luggage. It carried everything I needed and I still had room for just-in-case situations. No regrets.
 At Last
By Peter G, Melbourne, Australia, March 1, 2012

Well designed and finely crafted, this bag holds a deceptive amount of gear which is easily accessed in the divided compartments.
 Perfect for my intended use!
By kaliforniagal, Southern California, February 29, 2012

I have gotten myself down to just one carryon and my purse, but when I had an unexpectedly long layover (due to weather, overbooking of a flight, or whatever), I found carrying around my zippered tote bag or duffle bag to be hard on my shoulder, even if I switched the bag between shoulders. I wanted a bag I could fit what I needed into that I could put on my back so the weight was not all on one shoulder.

I have only just purchased the bag, but tested it by putting stuff into it and trying out the straps. It feels comfortable, and I like that the straps are padded. If I do want to carry the bag on one shoulder, I find the grip on the shoulder strap to be VERY helpful for keeping the bag on my shoulder (a real struggle with my other options I have tried). I think this bag will work out really well for me, and I purposely bought it to last a LONG time. It is definitely very sturdy, and the flaps over the zippers will help protect it if I find myself traveling in rainy weather.

The size of the bag is perfect for the biggest "cube" organizer that I use to pack my things in. Using the "cube" system works very well with this bag. Having open compartments is a big plus for me. The inside compression straps are very handy.

I like having the flat zipper compartment on the outside. It will be very handy for keeping my plane ticket, bag of liquids, etc. handy for when I go through security and while I wait to board the plane.

My one small negative is that I have to be a bit careful pulling the zippers around the corners, because sometimes they get a bit stuck. But that is very minor, and as I use the bag, I'm sure I'll get the hang of how to zip it up.

One very positive thing for me is that there are enough color choices that you are fairly sure to get it in a color you really like. I chose the purple one.

I just love it when a company works as hard as Red Oxx does to make a quality product. I look forward to using my new bag on my next vacation. If all works out, I hope to make it to Europe using this bag -- and it is my goal to not have any checked bags to deal with. I want to enjoy my vacation, and not spend it trying to keep up with my stuff, especially since such trips tend to find one sleeping in a new place just about every night. I think this bag will help me with that.
 Love the backpack, high quality
By Phil, Duarte CA, February 18, 2012

We bought the Sky Train for my wife based on how much I love my Air Boss. We were going to get another Air Boss, but my wife thought the backpack option of the Sky Train would be a better match for her, and it is. After a couple trips this has become her favorite bag. She loves the 2 large-ish (rather than the 3 medium-large-ish Air Boss) compartments, and that it has plenty of room for her clothes, shoes, makeup, etc. It suits her packing style and can easily be carried by her. Bonus is that storing our soft-side bags is easier than storing our suitcases when not in use. Like the Air Boss, the sturdy construction of this bag is pretty much bomb-proof. Also like the Air Boss, this is a deceptively large bag... you can put a lot more into it than what you would think just by looking at it.
 The perfect bag for me
By Scott B., SLC, UT, February 16, 2012

I had the Sky Boss for two years and really liked it, but had some difficulty with a fully loaded bag and the one shoulder strap. I broke down and got the Sky Train and am glad I did.

The backpack straps are comfortable and well made. They even the load on my back and keep my hands free while moving around. I love being able to zipper them into their own compartment when not needed, and the carry handles on two sides are a great plus.

I use my own compression strap to help with a bulky middle that is a problem with soft side luggage. It also helps with load shift. I would have love one built-in, but I can see that would be a design problem.

This bag is not for people who love wheeled luggage. You'll never enjoy this, or any full carry bag if you need to keep your weight on the ground. Even though you have to deal with leaving your wheeled bag behind on regional jets, stick with it. This bag's not for you. (Although, for the life of me, I can't see how you can, in good concious, wheel that thing through airport bathrooms, walkways, parking lots, etc. and then put it on your car seat, airplane seat, or even your bed)

If, like me, you're an aficionado of, want the most room in a single bag, and never want to loose contact with your bag, even on regionals. Then Redoxx makes the best options in Sky Boss and Train.

I'm going for a 15-day trip this year and this will be my only bag. I will not run the risk of lost, stolen, or damaged personal items, so I insist on keeping my bag with me at all time.

Every time I get off a plane with my Redoxx in hand, and walk by everyone waiting and hoping they get their pink-tagged bag back, I am grateful I've shed the wheeled carry-on forever.

***Red Oxx replies*** The bag Scott calls a "Sky Boss" is actually called the Air Boss.
 Not quite for us
By MrsSquid, Virginia, February 11, 2012

The bag is very well constructed - nothing dainty or lightweight about it. It holds a lot of stuff. Even so, you need to watch the weight. My husband packed it so full, I almost fell over trying it on as a backpack. I'm sticking to wheels. He uses it some but not as much as he thought he would. He prefers his laptop and work-related stuff in a backpack and clothes in a wheeled carry-on.
 Good but not great
By Anonymous, Seoul, South Korea, February 9, 2012

Sky Train allows you to pack a ton of things inside. It is built to withstand hard use and abuse. But there is a price...weight. A similar loadout I have had in other bags did not strain me as much as it did when using the Sky Train. I loaded for a 7 day business trip across the Midwest and East Coast. But only on the Sky Train, did I leave with a pinched nerve in my back after wearing the backpack for a week.

Some things can be done to improve the Sky Train.

1) The two zippers the hold the backpack strap? You don't need two zippers. You can get by with one. The purpose of those zippers is to hold the backpack straps inside. Well when the straps are deployed, the zipper is open. Don't need the extra zipper because it becomes redundant. Plus the tooth gauge is way too beefy for the purpose. Zipper just holds the backpack straps inside. No need for monster size zipper teeth. One zipper pull and smaller teeth. Maybe save a few ounces there.

2) The small pouch inside the front compartment where you can hold a pen or coins? Don't need two zippers there also. Plus the zippers used are the beefy YKK ones. Maybe use one zipper and a smaller zipper design.

3) Metal buckles? Bomb-proof but heavy. Consider a similar strength buckle but made of plastic?

4) The strap adjusters are also bomb-proof metal. Save a few ounces by changing to a lighter weight, possibly plastic?

5) The large front pouch or pocket. Great place to put your personal items when going through airport security but once you put your cell phone, wallet, watch etc. in there, the items swim around and disappear to the bottom. Maybe some sort of divided pocket would be easier to retrieve items instead of having to open the bag all the way after going past security.

Aside from that, the bag works good for travel. Fits nicely into the overhead bins on airplanes. The Sky Train is over built for the purpose. But take that as a positive. It most likely will never let you down, but you pay the price in terms of weight.

If Red Oxx could take a pound out of the bag then I think it would be much more enjoyable to carry/wear.
By Steven, NY,USA, February 9, 2012

Skytrain is a great combination for travel. You get the maximum possible volume to use as carry-on and the shoulder carrying capability. Bag is made from very sturdy heavy duty materials. Zippers feel very confident and those hard plastic side handles are a great idea. Don't feel afraid to give it an extra push to make it fit into that overhead compartment. It can take it. I have seen many people with hard-case carry-on wheels struggle to make them fit into those overhead compartments. No such problems with this type of bag. Sometimes plane runs out of overhead space before everyone boards. Those with wheeled carry-on are forced to check them in, but with Skytrain, I was able to fit it into the space under the seat in front of me.

If the bag is loaded to the max with heavy things, it can be difficult to carry for a long time. Difficult in a sense that your back will let you know about it. There's no ergonomic problems with the bag itself. I did that once and almost wished I had taken an extra wheeled bag to check in instead. Depends on one's level of fitness I suppose.

Only one compartment has tightening belts to compress contents. It would've been nice to have those for the second compartment as well.

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.
