Thermarest Parsec 20F/-6C

Engineered for your fast and light adventures, the Parsec delivers lightweight and packable warmth. Just like an alpinist precisely selects his rack or a skier carefully chooses her line, we took the time to dial in the small details that create comfort and security in the mountains. After you break camp, the mummy-style bag uses a compression sack to easily fit into your pack without weighing you down. Designed with high-quality materials and Therm-a-Rest performance features like SynergyLink Connectors, the Parsec easily handles three-season bivys and long pushes into the backcountry. Bottom line, those that need their sleeping bag to go further choose the Parsec. Storage sack and compression stuff sack included.

• 800-fill Nikwax Hydrophobic Down: Dries 3 times faster than untreated down without using dangerous PFCs.


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


• ThermaCapture Lining: Top of bag is lined to trap radiant body heat and retain warmth without adding bulk or weight.


• Zoned Insulation: Maximizes warmth and saves weight by intentionally placing fill where you need it most. The Parsec places 60% of the fill on top and 40% on the bottom to give the bag an elite warmth-to-weight ratio.


• Toe-asis Foot Warmer Pocket: Ergonomic toe box that rapidly warms cold feet in a pocket of warm down.


• Quilt and Blanket Loops: Customize your sleep system by layering our quilts or tech blankets for increased warmth
