I purchased the 35L and when it arrived, I decided to order the 45L also. The 35L didn't 'seem big' upon arrival -- too big for daily carry but it's a minimal travel bag at least for me. I have had the Outbreaker Laptop Backpack for a little over 2 years and have been completely satisfied with it for daily carry with a rather large work-issued Lenovo laptop and my fairly large lunch bag that I tote every day. The 35L and 45L are obviously purpose built for travel and they wreak of high quality design and materials. Personally, I think I prefer the 45L after 'practicing' with both. This may mean that I'm just an amateur one-bag traveler but I like the space and the ability to pack my must-takes and a few like-to-takes and still stay within one bag. I haven't traveled with them yet but will in the near future. Once adjusted for my frame, the straps seem near ideal. The back padding is quite firm and noticeable but I personally appreciate it. With either bag, I can easily pack a daypack such as my Outbreaker Daypack. I'll give my wife the choice of the 35L or the 45L and I'll use the other one. And I do guess I'll end up ordering the new 40L Travel Backpack since I'm a bag nerd and I'm curious to see how it compares. Then I'll probably offer one of these to my daughter since she's planning to travel overseas for school later this year. I'm definitely a Tortuga fan and have appreciated their service and their quick shipping.

Have wanted this backpack for years but didn’t buy it because was cost prohibitive! Have since tried the early version (Tortuga Setout) and the highly recommended Aer 3…neither of them compare to this baby! While the Tortuga Setout has the super-comfy backpack straps, it didn’t have the organization I craved. In contrast, the Aer 3 has FANTASTIC organization but the tech pocket doesn’t zip down all the way, the straps are NOT comfortable, and 35 L just isn’t enough room. In the end, I gave the other two backpacks to my young adult children and broke down and bought the Torguga Outbreaker. I should have just saved myself the heartache and done that in the first place. This backpack is fantastic and I LOVE, LOVE, LOVE it! Am so happy that I was able to get it before it was discontinued! While I know not every bag is right for every person, this backpack is great if you are like me who needs an all-in-one bag that has organization down to a science! Don’t delay…get it now!

I spent a really long time comparing brands and other travel bags, and couldn’t be happier with my final decision to get this Tortuga 40L Travel Bag. It’s extremely durable, light and well balanced on my body. It’s a little more bag than you may need for a short work trip or long weekend trip (unless you want to throw in extra shoes or many outfit changes), but has served me well on 1-2 week travel. Packing cubes nest really well inside too. If you’re on the fence, jump and get this bag.
