I have an off-brand 2L camelback that I love to fill with ice and water for my short overnight/2-day trips. That way, I have ice-cold water for most of my trip. It also has a few small pockets/compartments so that I can use it as a daypack once I get camp set up.
I usually just hang the shoulder straps over the top of my backpack when hiking in/out. See here -http://www.facebook.com/photo.php?pi...&id=1325224055
I don't like this setup, but don't really want to give up my cool water or my day pack.
A backpack with a hydration chamber would help with the carrying issue, but won't help as far as a day pack goes.
Is it plausible to carry the water in the backpack hydration chamber AND have a separate day pack with a hydration chamber rolled up in the backpack for use once camp is set up?
Curious?!
