Thermarest Hyperion -6C Sleeping Bag

The Thermarest Hyperion -6C Sleeping Bag weighs just 539g. It defies the cold and provides better rest while moving through the mountains.

Built to provide a featherlight pack weight and high-performance warmth, the Hyperion 20F/-6C sleeping 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 like SynergyLink Connectors, the Hyperion keeps your pack light, giving you the freedom to move quickly in the backcountry. 

Features

• Ultralight: One of the lightest pieces in its class, the Hyperion sets a new standard for high-performance outdoor equipment.
• 900-fill Nikwax Hydrophobic Down: Stays drier and maintains loft 60 times longer than untreated down.
• Unrivaled Packability: Lightweight materials and precise design allow for a smaller packed size than ever before.
• Box Baffled Construction: Uses mesh walls to maximise loft and minimise cold spots in key areas.

• SynergyLink Connectors: Integrate the bag with a mattress for optimal efficiency and comfort; removable for versatility.
• Zoned Insulation: Maximises warmth and saves weight by intentionally placing fill where you need it most, 70% on the top and sides with 30% on the back.
