I got an REI branded backpack decades ago. After about 15 years, it was starting to show some wear. I happened to have the receipt still, and I took it in and since they didn’t carry the same model anymore the just refunded the full purchase price.

Idk what a backpack by REI goes for these days, but that impressed the shit out of me. (Note: they would have had fewer options if I hadn’t kept my receipt.)

Otherwise, I picked this up about 4 years ago and it’s still in like new condition, and I use it daily. I love it for the amount of space, and the laptop pocket opens from the back of the bag without having to open the main compartments. (This also means I feel safe keeping snacks in my bag bc the laptop pocket is completely separate and never gets crumbs in it, even if something spills in my bag.)
