11 years and counting

I bought this bag 11 years ago when I was in college. It has more than withstood the test of time - I still use this bag on a daily basis with only some mild wear on the inside vinyl waterproof lining that has affected its waterproof-ness (though based on what I read on the company website, this is covered as part of their lifetime warranty!). Pick your colors carefully because you'll never need to buy a new bag.
