Designed for everything from daily carry to full travel, it adapts to your needs with a flexible capacity that expands for longer trips and compresses for everyday use—all while meeting international carry-on requirements. Multiple access points—including top, side, front, and rear—make packing and unpacking effortless, while weatherproof UltraZips are built to withstand decades of use. Inside, the main compartment can be organized into separate sections, with dedicated padded sleeves for laptops and tablets. Thoughtful storage is everywhere, from quick-access pockets for essentials like keys and passports to large expandable side pockets for water bottles or tripods.

I have a lot of different backpacks - hiking, mountain biking, backpacking, ski touring, work, you name it. The 45L is by far my favourite backpack.. So much so that apparently I feel compelled to write a review about it LOL
First off, if you're thinking about buying the bag, watch the video walkthrough of it on YouTube. That was extremely informative for me before purchasing. It's just so versatile. I travel alot for work - every 6 weeks - and this bag has been a gamechanger for me. Its extremely well organized, fits with various packing cube systems (I have a 3rd party brand), and fits my big honking hydraflask water bottle on the outside of the bag which I appreciate.
The ability to shrink the bag to a 30L size is useful once I'm at a destination and want a slightly smaller, more work oriented laptop.
I've started to use it as a duffle bag too now for personal vacations/road trips/weekend getaways. I tuck away the shouldwr straps, unzip the middle divider, and now I have a duffle that I can just carelessly toss clothes into.
Seriously great bag. A pricey bag, but an incredible bag.

Buy only if you can accept poor quality products.
Purchased in 2022, used the bag approximately once or twice a year when I go on long trips.
1. One zip handle tore.
2. Silicon mesh pocket flaked very badly
3. Material covering/protecting the zip broke
I do not handle my bag roughly and when I travel I use this bag to supplement my large full size luggages.
Read raving reviews about the bag and how some used it for years before I purchased it. The breakdown of materials started occurring less than 2 years during my once or twice yearly long trips.
Note: tried to attach photos to this review however unable to do so.

Best backpack overall
I bought this backpack in April of 2022, almost exactly 4 years ago and I have to say I love this backpack. BUT unfortunately, I lost the chest strap after 1 year (which is holding by simple pinching hooks, so easy to loose). Also, the main zipper only lasted 3 years. I've been dealing with this broken zipper for 1 year now. I did not yank on it nor anybody else around my backpack. This happened from simple day to day use.

Versatile Choice for Camera and Non-Camera
Purchased for a trip to Kenya with three locations. Used in conjunction with a large camera cube, Neoprene body bag, small neoprene pancake lens holder. I carried a 150-500mm, a 70-180mm, a 26mm, Nikon Z6 body, large bathroom dop kit, puffy jacket in a compression bag, paperwork, 3 batteries, large rocket blower, camera strap and various other items. Very useful on safari drives where I could carry my puffy jacket, rain jacket and camera outside the camera cube and other gear in the pocket areas. Weight with gear was about 26 pounds. The backpack itself is about 8 lbs, which means solid protection, and weight. I love the design, but even if that does not float your boat watch the YouTube videos and check out the versatility. Best backpack I have ever owned. For at home, I will get an extra-large cube for my longer lenses.

Amazing Bag!
This has quickly become one of my favorite bags. It is beautiful and functional. I have a rather large, bulky, laptop that isn’t easy to accommodate; however, this bag’s dedicated laptop storage handles it just fine.

Almost perfect travel backpack
Bought the 30L version of this travel backpack and have traveled with it now maybe 4-5 times. Love how the bag opens up for easy packing and access to everything inside (no digging around inside to find what I want). Also really convenient to have access on the top side, especially when the bag is stowed under the seat in front on the plane. It's almost perfect except for one big miss IMO. You cannot easily slide this bag on top of a roller bag handle in the upright position (like every other backpack)! You have to turn it sideways and then hold the strap on the back open while mounting it onto your roller bag handle. I don't get it. It's very awkward. Fix this and I would give it 5 stars instead of 4.
