Techonaut 45 Key Features
However You Haul, it Keeps Up
Backpack, duffel, or side carry — the Techonaut adapts to how you move, not the other way around. It’s built to handle the load of travel.
No Digging, No Drama
Three quick-access pockets keep your passport, phone, headphones, or mid-flight snacks close at hand.
Room for the Unexpected
Dirty laundry? Muddy pair of shoes? The dual end pockets expand when you need it, seemingly disappear when you don’t — because no trip ever goes exactly as planned, and that’s the point.
Your Laptop’s in Good Hands
Built-in protection without the bulk — the suspended laptop compartment keeps your laptop safely off the bottom, buffered from the bumps and thumps that come with travel.
Let It Breathe
Breathable skeleton back panel with soft mesh adds comfort without trying too hard. Airflow where you want it, structure where you need it.
Grab It Like You Mean It
Cushioned grab handle and padded shoulder straps that tuck away when you don’t need them. They make hauling gear feel like a walk in the park.
Clip It And Forget It
Eight internal O-rings to tether your essentials. Keep the little stuff where you need it. No spelunking required.
Let Your Bag Catch a Ride for Once
No more juggling act. Slide the Techonaut onto your rolling luggage and let it ride shotgun — your shoulders will thank you.
Pack More, Unpack Less
Wide opening U-shaped main compartment that lays everything bare — no rummaging for your last clean pair of socks.

We came across the Tom Bihn brand on YT bag review videos. I can't emphasize enough how right the reviewers were in their adoration for this brand. I have never owned a bag of such quality in my life. This bag will last me for many, many years and feels indestructible.
The straps are extremely comfortable and do not dig into my arms or shoulders. The opening of the bag is where it excels - you can pack it like a suitcase, with the sides that sit up and don't collapse, and fit enough for a long or short trip. The laptop compartment is great - no need for a sleeve. There is a pocket inside the bag I use for my flip flops, and I like the bottom compartment for my shoes. I also use packing cubes that I tie down with the internal straps, leaving plenty of room on top. I customize what I carry with a variety of Tom Bihn accessories. I've also added a photo of the bag sitting comfortably at my feet under the seat on an AA flight.
I can't speak highly enough of this bag, only to add that now my husband and daughter own one as well!

The Techonaut 45 is an amazing bag. I had no problem fitting four days' worth of clothes in the main compartment and two pairs of shoes in the bottom compartment. The laptop pocket comfortably fit my 13.3 inch Macbook Air, and the side pocket comfortably fit my 40-ounce Hydroflask. Fully packed, the bag was easy to carry as a backpack (and I'm an objectively small person).

I am a new customer and am loving this bag so far, one week into a 5-week UK adventure. The fabric is impressive: strong, lightweight, and beautiful. The zippers move smoothly and easily, clearly a superior product. I love the layout of the bag. My collapsible hiking sticks fit inside and I have packed my daypack in as well. The packing cubes fit perfectly into the two compartments of the bag, keeping clothes organized and easily accessible. Fully packed my bag was 21.5 pounds. I decided to check it rather than carry it on the international flight, but I believe it would have met carry on standards with a bit of repacking.

I love bags, but it's rare that just thinking about one makes me light up. When I was searching for a good travel bag for multi-day solo trips, something that could double as a duffel when needed, I did a bunch of research. After making the rounds, I kept coming back to the Techonaut 45. Granted, I couldn't see it in person, but from what I could see from the images, videos and posts on the Tom Bihn forum, it seemed like the right balance of laptop storage (for a 16" laptop — which most bags I found can't accommodate), durability and storage.
When I unboxed it, I had a good feeling but I knew it wasn't until I could put it through the paces that I'd really know whether the leap I had taken was a good one. I packed it to the gills and flew to Portland for the weekend to meet up with a friend. From the moment I put it on my back, I knew I had made the right choice.
What astonished me whilst walking through the airport terminal was that for as heavy as the bag felt when lifting by one of the solid handles on the top or the side, when it was on my back it felt like half the weight was just...gone. The weight distribution and the padding on the straps is just right. It fit effortlessly into the overhead compartment on the plane, and once at the Airbnb, it was delightful to live out of — each item in its own pocket, clothes neatly packed in Tom Bihn travel cubes in the main compartment, even my bulky hiking boots neatly fit into the side compartment.
This bag is everything I…

This bag truly holds it all. I was very close to bringing it on my ten day trip to Costa Rica but I just couldn’t quite fit all I needed comfortably but it would be perfect for 7 days. I cannot wait to take it with me on my next trip. It has loads of space and so many perfect side pockets and hideaways. And it’ll fit up on the plane so I won’t have to check a bag. Also, this is a forever bag. The craftsmanship is superb and I can’t wait to invest in more. Further, it’s incredibly comfortable to carry on my back and chest.
