Samsonite, I'm on my 3rd backpack of theirs. I've been using them since I was about 11 or so, I'm 26 now.
They're not officially water or wear proof, but they've always been that way in my experience regardless. Even after years of daily use,and I was a weird school going kid that liked his bag heavy.
Their zippers failed on my on both my previous bags, when they got really cold in the winter. I don't know if it's the less cold temperatures of today, or whether they've improved their zippers, but they've not failed on my latest bag. Which is currently about 13 years old I think? It looks as good as new still
Agreed. The zipper on My Samsonite roller case has been abused beyond belief and generally tested to breaking point over and over, and yet it resists and basically feels as good as new. Of course, I paid top dollar for that thing. You do get what you pay for.
