For a light pack and a good night’s sleep, the Therm-a-Rest Hyperion 32-Degree Ultralight Down Mummy Sleeping Bag provides peak performance for backcountry pursuits. The bag uses thermally-efficient box baffled construction in key areas to ensure warmth and comfort. Designed with high-quality materials and Therm-a-Rest performance features like SynergyLink Connectors, the Hyperion keeps your pack featherweight without sacrificing performance. ThermaCapture Lining traps radiant body heat and retains warmth without adding bulk or weight while zoned insulation maximizes warmth and saves weight by intentionally placing fill where it’s needed most, 70-percent on the top and sides with 30-percent on the back. The Hyperion Mummy Sleeping Bag is also Responsible Down Standard Certified ensuring that the waterfowl in the down supply chain are treated humanely.
