Large Standard Daypack
Product Review (submitted on April 3, 2012):
I've had a Day Pack since college and it's still like new. It will be one of my best friends in grad school.
My boyfriend is an archaeologist and once I introduced him to the Day Pack, he hasn't used anything else. It's near waterproof and hardly gets and dust, sand, or soil in it. You can beat it up all you want and it keeps on kicking.
