Spark Women's Down Sleeping Bag

Built for women who want minimal weight but maximum comfort in their adventures, the Women's Spark lineup demonstrates Sea to Summit's 100% commitment to building a sleeping bag that's perfect for you.

Women's specific shape and body mapping result in warmth and comfort without the weight. RDS-certified 850+ fillpower goose down treated with a non-PFAS Ultra-Dry Down treatment provides superior insulation, while a technical hood and zipper draft tube prevent precious warmth from escaping. A super-breathable 10D liner fabric rounds off the comfort profile, and a 10D shell with a non-PFAS DWR combined with a highly water repellent hood and footbox fabric keep moisture out

Couples can zip the full-length zipper Women's Spark to an equivalent Unisex Spark for extra comfort and thermal efficiency.

Customer Reviews (4.8 / 5 · 5 reviews)

Steven ★★★★★

Took this on a three-night trip in the Cascades and stayed toasty down to about 30 degrees. The down lofts up fast after being stuffed all day, and I love that it packs down smaller than my old bag.

Aurora ★★★★★

I'm 5'4" and the women's-specific cut actually fits my shoulders without dead air at my feet, which I've never had in a unisex bag. The down lofts up fast after being crammed in a stuff sack all day, and I stayed warm through a frosty night in the low 30s.

Mia M. ★★★★★

Took this on a three-night trip and the down lofted back up fast every morning. The women's fit keeps the extra insulation where I actually need it, so I stayed warm without feeling bulky.
