Therm-a-Rest Hyperion 0° Regular Sleeping Bag

The Therm-a-Rest Hyperion 0°C sleeping bag is designed for hikers and mountaineers who want to travel light without sacrificing their sleep. Particularly compact and lightweight, this three-season model offers a comfort temperature of 5°C and a limit temperature of 0°C: ideal for treks, bivouacs, and itinerant adventures in warm weather.

Its Nikwax Hydrophobic Down™ 900 CUIN goose down fill offers an excellent warmth-to-weight ratio. It absorbs 90% less moisture and dries three times faster than conventional down, while retaining its loft for a long time. The down is also RDS certified, guaranteeing traceability and better practices in terms of animal welfare.

Its mummy cut, adjustable hood, draft collar, and insulating draft tube effectively limit heat loss. SynergyLink™ connectors also allow the bag to be attached to the sleeping pad to keep you comfortably settled all night long. Delivered with its compression sack, the Hyperion 0°C takes up minimal space in your backpack. In short, a featherweight for a warm night's sleep.
