>>1918097>putting everything in dry bagstotally unnecessary,just throw them in a regular stuff sack if you want a way to organize your loose items, or in a black trash bag if you're scared of getting it wet.
Rolling up and deflating those dry bags each time you want to get something will become a pain in the ass very quickly
but if you insist, walmart sells dry bags for dirt cheap
