The MSR E-Bivy bag, tiny and weatherproof, adds a quantity of ideal protection for many situations, without adding much to your bag. It will block the wind, dew, mist and even the light rainfall, adding warmth and comfort valuable when used under tarps on open bivouacs, and winter camping. It can also be cast into the top pocket of a bag for any tour, and thus provides essential protection unprepared for a night in the hills.
