Therm-a-Rest Parsec Sleeping Bag: 20F Down Reflecting Pond, Long

What Our Gearhead(R) Experts Are Saying:"I bring the 20-degree Parsec when I want real warmth on high-mileage trips without carrying extra bulk. The 900-fill down lofts quickly, the foot pocket works incredibly well on cold nights, and the bag compresses much smaller than most others in this temperature class."We reach for the Parsec 20F Sleeping Bag when our routes stretch into colder shoulder-season terrain and efficient warmth makes every mile feel more manageable. Therm-a-Rest fills the bag with lofty, compressible 900-fill hydrophobic down, giving us serious insulation at a weight suited for fast-moving backcountry travel. Zoned construction concentrates heat where we need it most, and the overall fit strikes a thoughtful balance between thermal efficiency and natural movement. When temperatures slide below freezing, the cinchable hood and draft collar help seal in warmth while the Toe-asis foot pocket provides a dedicated warm zone for chilled feet. A smooth anti-snag zipper keeps late-night exits simple, and an internal stash pocket protects essentials from cold-sensitive battery drain. With a soft recycled shell and compact packed size, the Parsec is built for long approaches, high camps, and any trip where reliable warmth and low weight must coexist.
