Therm-A-Rest Parsec 0F/-18C Down Sleeping Bag
When the forecast calls for cooler temps, you can rely on the Parsec. It’s the perfect choice for year-round comfort at minimal weight on chilly alpine nights thanks to new, premium 900-fill hydrophobic down. The soft, durable recycled nylon shell is easier on the planet, while the anti-snag YKK® zipper prevents wear and tear with easy entries and exits. The updated baffle structure and zoned insulation strategically locate more down in priority areas, while our down-lined Toe-asis™ foot pocket gives you a place to rapidly warm cold feet. Finally, an internal stash pocket holds your phone to preserve battery against the cold or keeps a small water filter from freezing.
