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 made 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)

Sophia D. ★★★★★

The temperature range is spot on for my shoulder-season trips, and the mummy cut actually fits me without extra fabric bunching up. It's noticeably lighter than my old bag, which makes a real difference when I'm hiking in a few miles to camp.

Stella J. ★★★★★

Took this out for a three-night backpacking trip and the 15°F rating held true even when temps dipped to freezing. The draft tube along the zipper kept me warm on my side, and the hood cinched down snug without feeling restrictive. Only wish the stuff sack had a bit more room, but the weight savings

Joseph X. ★★★★★

The way it compresses down is honestly the selling point for me—I got it into a stuff sack smaller than a loaf of bread. For a bag rated down to 15°F, that kind of packability feels like a cheat code for backpacking. Even the “like new” condition had zero signs of wear.
