I highly recommend Jansport. They're durable, comfortable and have a lifetime warranty that the company actually supports. I found my first Jansport lying empty in some bushes in London in 2002. It was in good condition so I took it home and washed it and used it daily till the zip failed around 2009. By then I was home in Australia so I contacted Jansport, sent them photos and a couple of weeks later a replacement one turned up. That replacement has been my daily from then until now and it's still going strong! 13 years is pretty impressive in my eyes and if it does eventually fail....I'll definitely get another one from Jansport. Hopefully under warranty again. 😁
