Hi Folks,
I've heard a lot about using a trash compactor bag inside your pack to hold a sleeping bag, etc. This may seem like a dumb question, but... how do you close/seal it? I mean, if you want to be able to compress it, don't you have to leave it un-sealed? But does it do its job that way and keep the contents dry? I bought a box of these things at the grocery store, and they're big enough, I'm guessing people just put the contents in, roll it around itself, and stuff it into the pack, and that's enough to keep water out.
Thanks, and sorry for the dumb question but some of these practices are new to me.
