Snugpak Sleeper Xpedition sleeping bag - Olive RH zip

I personally use the sleeper lite for backpacking but this is the bag for really cold weather.

Filled with a "siliconized hollowfiber." These synthetic fibers are structured to trap warm air between tiny cavities in the fiber. When unpacked the hollow fibers decompress and spread back to gain maximum re-loft. Ripstop nylon outer with supersoft as the inner lining, a silky smooth nylon fabric. All sleepers come with a compression stuff sack, Snugfit hood, zip baffle, hanging dry tabs, and anti-snag two way zip.
