I have used this backpack for 5 years now and it is the best backpack i have ever used. I do alot of different activites and have backpacks that serve those purposes, but i find myself using this one for almost everything. I am a student and i train alot, so a packpack which you can store your gym clothes, books and pc is really handy! Sometimes i buy groceries aswell between school and training and i just use the zipper that expans the backpack and then i have room for even more stuff, super nice feature. And sometimes i get carried away and overload the backpack with alot of stuff and i am really suprised that the zippers havent broken yet, i really mean it, i have really abused the backpack and it still works fine (still after 5 years). A buddy ask me for a recommendation, and without a hasitation i recommeded this one, but it looks sold out everywhere. Would love to see this one in stores again. Really great job with this one guys. Kudos to you!
