Therm-a-Rest - Parsec 20

Engineered for your fast and light adventures, the Parsec 20 delivers lightweight and packable warmth. Just like an alpinist precisely selects his rack or a skier carefully chooses her line, Therm-a-Rest took the time to dial in the small details that create comfort and security in the mountains. Designed with high-quality materials and 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. Pad sold separately.

California WARNING: Can expose you to toluene, which is known to the State of California to cause cancer. P65Warnings.ca.gov
