  • 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.
