Thermarest Hyperion Sleeping Bag 20F/-6C

• 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: Removeable ultralight straps create a secure bag-to-sleeping pad connection that optimizes the comfort and thermal efficiency of your entire sleep system. SynergyLink Connectors function best with regular sized sleeping pads that are 3 inches thick or less when inflated.
• 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.
