Sea to Summit · Sleeping Bags
The Spark Sleeping Bag is designed for cold-weather lightweight adventures with a 15°F rating. It features durable nylon fabric and hydrophobic down that resists moisture to maintain warmth and loft. The mummy shape reduces weight and retains heat, with a 3/4-length zipper for easy entry and exit. The hood and footbox resist tent wall condensation, and the women's specific fit offers extra room around the hips.
