>>351775I have an East German pack that I use as kind of a big daypack.
I like it, it's got a waterproof liner and the top folds over to keep water from getting into your stuff.
The regular material is waterproof as well.
Fits most of the crap I'd need while still being kind of roomy for a day hike.
They're dirt fucking cheap too.
Got mine at a local surplus store for like fifteen bucks with all the attachments in brand new condition, but you can get them cheap online too.
