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

Whether on an overnight snowshoe, ski tour or just a quiet, off-season backpack, the Parsec 0F/-18C sleeping bag provides plenty of warmth for winter pursuits. Filled with highly compressible 800-fill Nikwax Hydrophobic Down that absorbs 90% less water and dries 3x faster than untreated down, the Parsec keeps you warm and dry in wet conditions. The ultralight 20-denier GRS-certified 100% recycled nylon shell is a smart choice for saving weight and the planet, while the new anti-snag YKK zipper prevents wear and tear with easy entries and exits. Improved—and optional—SynergyLink Connectors strap to your sleeping pad to keep your sleeping bag in place to boost comfort and overall warmth efficiency. A refined shape shaves up to 2 oz off the previous version while adding a bit of girth in the shoulder to accommodate more clothing layers. Cold feet in the dead of winter? Not a chance, our down-lined Toe-asis foot pocket keeps your feet cozy all night long.
