Built to provide a featherlight pack weight and high-performance warmth, the Therm-a-Rest Hyperion Sleeing Bag is among the lightest in its class without sacrificing an ounce of performance. The bag uses thermally efficient box baffled construction in key areas to ensure warmth and comfort in an ultralight package. Designed with high-quality materials and Therm-a-Rest performance features, the Hyperion keeps your pack light, giving you the freedom to move quickly in the backcountry.
