So, I recently got my first down bag. It's a Marmot Sawtooth 15. It packs down into the stuff sack that came with it but, from what I understand, it may be a good idea to get a dry sack for it since down loses its insulating quality if wet. My question is what size I should go with and what brand? Is there any real benefit to E-vent bags for a sleeping bag? Also, should I get one that doesn't pack it as small as it can get so I don't lose loft? It will be going in my Granite Gear Meridian Vapor and there's not a lot of room in there.
Also, what size sack to you guys/gals use for food? I have been using an old sleeping bag's sack for years but it's seen better days and it's time to pick up a new food bag. Thanks!
