Stay in Rab's Summit 800 Sleeping Bag until the sunrise warms up the alpine campsite you backpacked into. Rab's Hydrophobic Down makes sure the light and lofty 650 fill down stays warm in moist environments. The bag's Pertex Endurance shell offers reliable windproofing, comfortable breathability, and high levels of water resistance for extra protection. Rab designed the Summit Sleeping Bag with a snug, weight saving mummy shape, and the angled footbox prevents your feet from feeling too snug. A 3D draft collar works with the adjustable hood to keep cold drafts out. There's a full length zipper on either the right or left side, and an internal stash pocket keeps electronics running in cool temperatures.
