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.
