The Coleman Silverton 15 Mummy Sleeping Bag - Tall will keep you comfy and toasty down to 15F. The snug mummy shape with Coletherm filling and offset quilt construction will keep body heat close without any cold spots. A Thermolock full length draft tube along the zipper keeps heat in and cold air out. The sleeping bag features a pillow pocket to either fit a pillow or stuff with soft clothes for extra sleeping comfort. The ripstop polyester outer is durable and the polyester liner makes this an easy-maintenance sleeping bag. It's great for backpackers and adventurers planning to spend quite a few nights in freezing cold places.
