Ascent Sleeping Bag: 10F Down

What Our Gearhead® Experts Are Saying:

"I like the Ascent 10F for regular mountain trips where nights are cold but not extreme. The wide mummy cut gives you room to move, and the sidewall baffles keep warmth consistent even if you’re a side sleeper. It packs down well for the warmth you get and feels durable enough for repeated use."

We turn to the Ascent 10F Sleeping Bag when our trips demand dependable warmth without stepping into full winter-bag territory. It’s built for trekking and backpacking where cold nights are common, delivering a comfortable, confidence-inspiring sleep after long days on the move.

Designed with comfort at the forefront, the Ascent uses L.O.F.T™ baffle technology and sidewall construction to maintain even down distribution and minimize cold spots. The wide mummy shape, roomy footbox, and 3D neck collar improve sleep quality—especially for those who shift positions overnight. A Pertex® Quantum shell, hydrophobic 650FP European duck down, and thoughtful details like an arm access vent and smooth YKK® zippers make it a reliable companion for regular mountain use.
