Therm-A-Rest Hyperion UL 32 Bag

Keep the pack light and the nights comfy with the 16-ounce Hyperion 32 Mummy style bag from Therm-a-Rest. The baffling construction keeps you warm through the night, while reducing weight. The hydrophobic down provides extra loft (extra heat trapping) and stays drier. You'll forget the Hyperion is in your pack until it is time to set up camp! 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.
