Do any of you guys that hunt in that cold weather have a cold camp? I'm wondering what you guys do to keep your water thawed and your water filter from freezing, other than having it inside your sleeping bag. I don't have a stove, and sleeping with my water filter and water bottles is the only solution that I have found.
My warm sleeping bag (-10F) was purposely purchased in the Long version (usually use a Regular), just so I could keep water, electronics, etc in the bag for cold weather.
