The Spark Women's sleeping bag is the perfect option for lightweight adventures. Specifically designed for women, the added warmth and heat retention offers versatility and functionality. Featuring an optimal warmth to weight ratio, the Spark Women's bag is equally compact and comfortable.

The women's specific mummy fit is narrower at the shoulder and wider at the hip, and features extra down compared to the unisex Spark models.

Tech specs:

• RDS-certified, 850+ fillpower goose down with a non-PFC Ultra-Dry Down treatment for maximum thermal performance
• Ultralight, breathable 10D nylon liner and a 10D shell with PFC-free DWR keeps the hood and footbox highly water resistant
• YKK #5 zippers with zipper plow provide reliable, snag-free operation
• Women's specific fit means more narrow at the shoulders (for reduced weight) and wider between the hips and knees to allow for a natural, side-sleeping position
• Technical hood and anatomically-shaped footbox provide excellent warmth retention without the claustrophobic feel of some ultralight bags
