Category: New Winter Light Sleeping Bags

Think of the Eider as the Widgeon’s broad-shouldered sibling. It shares the same expedition pedigree (originally born from the 1990 K2 expedition) but offers a wider cut for those who need extra room. Now offered as an even lighter-weight option with Pertex® Quantum Pro® fabric, it remains a favorite for winter mountaineering and snow camping, giving you the space to wear a parka inside and push the warmth rating even lower.

Light: Winter & Expedition with Pertex® Quantum Pro® 7 denier x 30 denier ripstop shell fabric with 900+ Fill Power Down

Customer Reviews (4.8 / 5 · 5 reviews)

Alexander ★★★★★

The extra width in this bag is perfect for me—I can actually roll over without feeling trapped. It packs down surprisingly small for a winter bag, and the fabric feels tough enough for real backcountry use.

Olivia X. ★★★★★

I toss and turn a lot at night, so the wider cut of this bag is a total game-changer — finally, room to move without feeling trapped. The insulation kept me perfectly warm during a 15-degree test nap in my porch, too.

John ★★★★★

Feeling claustrophobic in mummy bags is the worst, but this one gives me enough space to actually toss and turn without fighting the fabric. The cut is noticeably roomier through the shoulders while still packing down small, and it kept me warm down to about -5°C on a frosty camping trip.
