The opinion of Aventure Nordique

For objectives that demand a light pack and a good night’s sleep, the Hyperion provides peak performance for uncompromising adventurers.

The Hyperion 32F/0C sleeping bag is among the lightest in its class while still providing high-performance during backcountry pursuits. 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 featherweight without sacrificing an ounce of performance.


    • 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 maximize loft and minimize cold spots in key areas.

    • Comfort Fit: Ergonomic shape and longer zipper provide a more human-friendly fit than other ultralight bags.

    • SynergyLink Connectors: Integrate the bag with a mattress for optimal efficiency and comfort; removable for versatility.

    • Zoned Insulation: Maximizes warmth and saves weight by intentionally placing fill where you need it most, 70% on the top and sides with 30% on the back.

    • Responsible Down Standard Certified: Certification that ensures that the waterfowl in the down supply chain are treated humanely.

    • Storage sack and compression stuff sack included
