Ascent Sleeping Bag: 10F Down - Women's

What Our Gearhead® Experts Are Saying:

"I like the Ascent 10F for regular backpacking trips where nights are reliably cold. The wide mummy cut gives you room to move without losing warmth, and the sidewall baffles really help keep loft consistent if you sleep on your side. It’s warm, comfortable, and built to hold up to frequent use."

We turn to the Ascent 10F Sleeping Bag when mountain nights dip well below freezing and comfort still matters. Designed for trekking and backpacking in cold conditions, it blends dependable insulation with a roomy, livable shape that helps us wake up rested and ready for the next day.

The Ascent uses L.O.F.T™ baffle technology and sidewall construction to reduce down migration and maintain even warmth throughout the bag. A wide mummy profile, anatomically shaped footbox, and 3D neck collar improve comfort for side sleepers, while thoughtful details like an arm access vent and smooth YKK® zips make it easier to manage long nights in the tent. Filled with hydrophobic 650FP European duck down and wrapped in a Pertex® Quantum shell, it’s built for reliable performance on regular cold-weather trips.
