Because the alpine is unpredictable.
Rab's Summit 400 Sleeping Bag is ultralight for summer trekking through the alpine, and it's protective just in case the clouds roll in. Its 650-fill down insulation has a hydrophobic treatment to stay warm in moist conditions. Rab wrapped this innovative insulation with an ultra-thin Pertex Endurance fabric for air permeability, breathability, windproofing, and high levels of water resistance.
The Summit 400 also features a snug, weight-saving mummy shape, and the angled footbox prevents your feet from feeling too snug. There's also an anatomically-designed 3D draft collar so you don't feel any cold breeze through the full-length zipper. Rab added an internal stash pocket for your headlamp, and it included both storage and compression sacks for added convenience.

Hand Filled in Derbyshire
Sleeping bags are firmly where we started and they remain a core part of our range to this day. Back in the 1970's when Rab Carrington was making sleeping bags in Patagonia, he probably didn't imagine that 40 years later sleeping bags with his name on them would be used all over the world in some of the most beautiful yet hostile environments.
To this day, we hand-fill our down insulated sleeping bags at our factory in Derbyshire, UK. This allows us to know for definite that, by the time our bags reach our customers, they have never been compressed or stored in a way which could be harmful for the down inside. By filling the bags in house, we can be completely sure that every down sleeping bag that leaves our factory will arrive to our customers in the best possible condition.
