Hi there... I am walking in the 3 Day Walk for the Cure and I need a back pack large enough to fit 2 water bottles, an extra pair of socks, some sun tan lotion, and a first aid kit, but small enough that I can carry it for 20 miles a day for 3 days without being a terrible burden. I want something that is no bigger than 12 or 13 inches. How does this rate and do you have any other suggestions?

I just got this pack today... it'll hold 2 (1 litre) water bottles, and everything else you mentioned easily. The pack its self is very minimalist and light weight, so it shouldn't be much of a burden. It has in internal pouch for keys and such. And it's hard to tell from the pictures but it also has a pouch for a hydration system with a covered hole at the top for the straw (which is better than carrying water bottles as you can drink while you walk, won't move around on you, and spreads the weight better.)... *this pack doesn't come with a water bladder and straw, just has room for one to fit in.... you might also want to check out hydration packs (camel packs) they might also fit your needs.
