I have a Thule backpack, think it is 32l storage. Had it for 15 years and taken it all over the world. The only thing that’s broken is some of the plastic “handles” to make the zippers easier to pull. Very happy with it.

Someone on Reddit created this website(I think) and it goes over a lot of different things https://theperfectpack.com/

Peak design travel backpack. Can hold 45 liters, but you can snap it down for a smaller profile. I did a ton of research and this one came out on top and I can’t be happier

I have more backpacks than my wife has purses… I also have more boots than her… lol

I don’t about 5.11 bags, but they’re clothing is pretty much destruction proof.

I have a swiss gear backpack that I bought in 2003 or 2004 and it still looks brand new (minus a little dirt). I used it everyday in college all the waythough my grad program and then daily with my first job for 5 years. Still use it to travel, but it’s a bit bigger than I need all the time so I only use it when I need more storage
