Overview

Box baffles with vertical torso chambers hold the goose down in place so it cannot drift away from the core. A women's cut narrows at the shoulders and widens at the hips and knees, and the zip system opens the bag flat as a quilt.

Shaped for women who sleep on their side, it trades shoulder room for hip room and treated down that resists damp. Total weight is missing, a gap for anyone counting grams.

Who it's for

Women on three-season trips who toss to their side and want a bag that converts to a quilt. Taller sleepers need a longer size.

Pros and cons

Pros
  • Women's specific shape
  • Water-resistant treated down
  • Opens flat as a quilt
  • Wearable with shoulder snaps
Cons
  • Total weight not listed
  • Fill weight not stated
  • Short height limit

Performance notes

Box baffles let the down loft fully instead of pinching at seams, and vertical torso baffles stop it migrating off the body. The treated down holds more loft in humid conditions, and the zip layout controls how quickly heat vents.
