// Around The World With One Bag (Part Two)


Because the Sky Train was more compact than the Tom Bihn Aeronaut, we decided that it would be Lauren’s bag on this trip.  But before we left the country, I took the Sky Train on a short, domestic trip with a few connections to test it out myself. Since it was just a quick turn-around, I ended up packing it lighter than Lauren would for our trip around the world. On both large and small planes, the Sky Train was able to fit into the overhead compartment. However on a smaller plane (a Bombardier Dash 8 for all you über-flyers), I had to kind of rock it back and forth until it fit into the bin and, in fact, I scuffed the bag while trying to extract it.

Lauren + Fully Loaded Sky Train = Ninja Turtle

From this experience (and from some “test packs” as we prepared for our circumnavigation), it became clearer that the Sky Train carries its substantial volume by expanding its depth. How much it could expand became clear as we boarded our first flight — a United 757 that is part of their roomier, Premium transcontinental service between New York and Los Angeles. Lauren’s bag, now fully packed, would not fit into the overhead bin no matter how I maneuvered it. Thankfully we had boarded the aircraft early enough to where I could run it up to the front and, with the help of a sympathetic flight attendant, stow it in a closet.

When we got to Tahiti and Lauren put the fully loaded Sky Train on as a backpack for the first time, I could see the issue even more clearly: The bag had expanded so much that she looked like she had grown a shell. No wonder it wouldn’t fit in the overhead compartment!

The moral of this particular lesson: This bag has got some serious Z-Axis for its size — so pack accordingly!


Lauren was able to fill the Sky Train with almost two week’s worth of clothes, two pairs of shoes, some flip-flops, her toiletries, assorted chargers and gadgets, a small umbrella, a laundry bag, and a few magazines. One key to getting so much stuff to fit inside were the compression straps in the main compartment.

Sky Train's Compression Straps At Work

After a minute or two of what I call Travel Tetris, Lauren could maneuver her items into optimum position and then “lock” them into place with the straps. At this point, the heavy-duty zippers with the monkey knots really came into their own! Sometimes it took her a while to get the Sky Train zipped up, but the zippers held up without jamming or sticking and, once closed, stayed closed without slippage.

“So — were there any drawbacks to this bag?”, you might ask. There were only a couple:

  • The metal fittings felt heavy compared to the Tom Bihn Aeronaut — which wasn’t always a bad thing. There was one flight where in our haste to check in our baggage, we forgot to stow the backpack straps. The spring-release mechanism that lets you attach and detach the backpack straps became bent from the loving care Lauren’s bag received from the ground crew. We could sort of bend it back into position and it wasn’t an issue for the rest of our trip. A smaller-profile part might not have been caught in whatever mangled it in the first place but, then again, a smaller plastic piece might have broken completely.1
  • We preferred the Tom Bihn Absolute Shoulder Strap to the stock Red Oxx strap and replaced it for this trip.


Lauren really enjoyed using the Sky Train and it held up beautifully over 3 months and 40,000+ miles (64,000+ km.) of travel — and we wouldn’t hesitate to recommend it to anyone looking for a “one bag solution”. It delivered what it promised: It’s a well-made, compact piece of gear that you can load up and take anywhere!

But the Red Oxx isn’t the only good option… In Part Three of “Around The World With One Bag”, I’ll review the Tom Bihn Aeronaut: A bag that, for some people, may be an even better performer than the Sky Train!

    This is one of the most useful reviews of the Skytrain that I’ve read. The “turtle” picture of Lauren illustrates how much it can hold, but also the need to be careful to insure it is relatively flat in order to get it on the plane as carry-on. This point is often missed in other reviews which merely praise how much one can pack into it.
    I did buy one, and I’m really happy with it; but sometimes I miss the structure of my Maxpedition, which avoids the turtle problem.

      Thanks Jack! I didn’t see much mention of it, either — which is part of why I wanted to write about the Sky Train.

      FWIW, I found the Tom Bihn Aeronaut to be more structured and having a less pronounced profile. Also, thanks for mentioning Maxpedition (hadn’t heard of them before!).

        Thanks so much for posting your experience with this bag. No offense to the guys out there who have reviewed this bag on other sites, but I was hoping to see what a fellow woman thought of this bag, and more particularly, assess opinions based on packing a similar amount of clothes / shoes as I would do. I hadn’t seen much detail until now about how many of a certain type of item one could fit in this bag.Anyway, I’m planning to go on a 10-day trip to Europe in November (half in Barcelona, half in Prague) and was wanting to take the opportunity to optimize my luggage situation. My current setup is a high quality carry-on by Atlantic. I am generally happy with it. The problem is that it doesn’t always pass the size limit for carry-ons, and is a LOT heavier than the Aeronaut. I would like to avoid paying surcharges for checked luggage, and overweight bags. I have a history of overpacking I also am concerned about maneuverability on trains, buses, etc. I’m very excited about the potential for this Aeronaut bag and like that it’s U.S. made. Thanks again for sharing your experience in such a detailed, helpful manner.

          I thought it was important to share Lauren’s perspective and experiences with these bags as well, and your comment makes me very happy that I have!

          An update: Tom Bihn just sent us an all-Dyneema version of the Aeronaut to test out which is a hair lighter than the original. (They say it’s about a 20% reduction in weight and, though I haven’t measured both bags, this seems right to me). It’s not as rugged as the original but, if you feel like you need the lightest version available, I wanted to point out that it exists!

          We’ll be beginning a trip tomorrow from the U.S. back to Asia (Bali, Bangkok, Laos) and I will update the review on my soon-to-be-opened travel site in the very near future!

    So thanks for the great review! I am planning on going to Paris and was trying to decide between these two bags. For some reason I want the Red Oxx, but feel that the Aeronaut is the wiser choice. One question, would the Sky Train have worked better if Lauren had used packing cubes for everything in the bag, as opposed to just some things? Thanks so much for your sharing your experiences. Melinda

    • Justin says:

      Hi Melinda,

      First off, I think that packing cubes are almost always a fantastic addition to people’s traveling gear. Lauren used a clear organizer pouch from Tom Bihn for her toiletries and make-up and one small cube for some items like socks and bathing suits.

      Her overall packing style, though, isn’t as reliant upon packing cubes as mine is. She likes to lay her garments flat inside her pack. Because of that, the more open, dual compartment design of the Red Oxx was the one she went with. She liked both packs, but I believe she preferred the sleeker material the Aeronaut was made from.

      The length of trip may also be a factor for you: if you are going to completely stuff the Sky Train, be prepared for it to not fit into overhead compartments or under seats. This isn’t a huge drawback if you like to check your luggage (or if you will be traveling by rail or bus once you arrive in Paris) but, if you are the type of traveler who never wants to check a bag, this could be a factor.

      Let us know which one you end up with and how it worked out for you!
