Therm-a-Rest - Parsec 0F/-18C Sleeping Bag

Cold nights demand a sleeping bag you can genuinely trust, and the Therm-a-Rest Parsec 0°F/-18°C brings the same ultralight down performance as the rest of the Parsec line with significantly more fill for serious winter conditions.

The fill is 900-fill PFAS-free hydrophobic duck down, RDS certified and loaded generously at 27 oz in the Regular size to handle temperatures well below freezing. The updated baffle design and Zoned Insulation concentrate fill strategically over the areas where your body loses the most heat, keeping warmth-to-weight performance as efficient as possible at this temperature rating. The Toe-asis foot pocket insulates the footbox separately, warming cold feet quickly at the end of a hard day on a winter traverse or late-season paddle route. An internal stash pocket keeps a phone or small water filter protected from freezing overnight, a practical detail that earns its place on cold-weather trips across Canada.

The 100% recycled 20D nylon ripstop shell and lining with DWR finish keep the bag light and weather-resistant, and quilt and blanket loops allow you to layer additional Therm-a-Rest pieces for extreme cold. YKK anti-snag zippers, draft tubes along the zipper and neck, and a cinchable hood seal in warmth when temperatures are serious.
