Sea to Summit Spark Women's Ultralight Down Sleeping Bag

About this item

The Sea to Summit Spark Women's Down Sleeping Bag is a technical down bag for backpacking, bike packing, and touring. The contoured mummy style features a shaped hood and zipper draft tubes to keep the cold out and the warmth in. High-loft, 850+ fill power down insulation (Responsible Down Standard certified) is treated with proprietary non-PFC Ultra-Dry Down treatment to improve reaction to moisture, retaining loft and performance in rugged conditions. Women's-specific design features include a shorter length, narrower shoulder, and wider hip to eliminate dead space and increase thermal efficiency; down chambers are mapped to a woman's physiology to maximize warmth. A super-breathable 10D nylon liner fabric offers cutting-edge comfort. The 10D nylon shell is treated with non-PFC durable water repellent finish to keep moisture out. The Sea to Summit Spark Women's Down Sleeping Bag is available in two sizes: Regular (max user height of five feet seven inches) and Long (max user height of six feet) and in three temperature ratings: 45-degree, 30-Degree, and 15-degree.
