Thermarest Hyperion 20F/-6C Sleeping Bag

The New Hyperion 20F/-6C is a super lightweight sleeping bag with a -6°C EN Rating, yet it only weighs 570 grams!

The Hyperion 20F/-6C is built to provide a featherlight pack weight and is among the lightest in its class without sacrificing high-performance warmth.

The -6°C EN Rating Hyperion uses thermally-efficient box baffled construction on the top surface, footbox and hood to ensure warmth and comfort in an ultralight package.

Designed with 900 fill power down and other high-quality materials and with Therm-a-Rest performance features like SynergyLink™ connectors, the Hyperion helps to reduce your overall pack weight giving you the freedom to move quickly in the mountains.

Storage sack, SynergyLink™ connectors and compression stuff sack included.
