A three-season mummy bag that keeps your precious body heat close all night.

You may find peace and solace trekking alone into a big green forest, but once night falls, the 15-degree Sierra Designs Utopia Sleeping Bag becomes your main source of comfort. The Utopia's Flex design uses elastic stitching to keep the quick-drying synthetic HeatSync insulation snug against your skin to eliminate cold spots, while still allowing you to move around in your sleep without constriction.
