Product details

Weighing a mere 1 lb. 6 oz, defy the cold and rest better while moving through the mountains with the Hyperion.

Built to provide a featherlight pack weight and high-performance warmth, the Hyperion 20F/-6C 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, the Hyperion keeps your pack light, giving you the freedom to move quickly in the backcountry. Storage sack and compression stuff sack included.


  • 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.
