We may be sending it back, waiting to compare it to another item we ordered.  It's for a trip and I think it will just be too hot and heavy for the tropics.  It's really stylish though, I love the rugged retro look.  Very good quality, tons of storage and pockets, very rustic and well made.  Because it is a vintage look and made of canvas it is heavy and thick.  I think it would be really cool as a book bag or a travel bag in a cooler season or climate.  I don't know if it would be waterproof, I would not count on that it's made more for looks and storage.
