Ascent -12C Sleeping Bag

Rab Ascent Down Sleeping Bag -12°C

The Rab Ascent Down Sleeping Bag -12°C is a warm and robust down sleeping bag for trekking, backpacking, and camping where comfort and reliable warmth are especially important. The spacious wide mummy shape offers more room than a narrower mummy sleeping bag, making it comfortable during longer nights and providing space for extra layers when temperatures drop. The sleeping bag is filled with 650FP European duck down with a fluorocarbon-free water-repellent treatment and features a windproof outer fabric made from Pertex® Quantum. The L.O.F.T™ construction helps keep the down evenly distributed, providing efficient warmth relative to its weight.

Please note that some features are demonstrated with the Ascent -24 and not the -12.
