Parsec Sleeping Bag: 32F Down

What Our Gearhead® Experts Are Saying:

"I brought the Parsec 32 on a shoulder-season alpine trip where overnight temps pushed into the mid-twenties, and it held its own without any extra layers inside. The Toe-asis foot pocket is one of those features that sounds gimmicky until you are lying there at midnight trying to warm up your feet after a cold summit push, and then it becomes the best thing in the bag."

The kind of trips that demand a bag like the Therm-a-Rest Parsec 32 Sleeping Bag are usually the ones where every ounce in the pack gets scrutinized twice. Fast and light alpine objectives, high-elevation shoulder-season routes, and long-mileage overnights where packability is as important as warmth all point toward the same answer: a bag that disappears into your kit until you actually need it.

The 900-fill hydrophobic duck down at the core of the Parsec 32 is PFAS-free and RDS certified, meaning it compresses down into a 7 x 10.5-inch stuff sack without giving up the loft that makes a 20°F rating credible on a cold night. The updated zoned baffle structure concentrates insulation in the areas that lose heat fastest, trimming weight without trimming warmth. A recycled 20D nylon ripstop shell with DWR treatment handles condensation and light moisture, while the anti-snag YKK zipper makes middle-of-the-night venting adjustments painless. The Toe-asis insulated foot pocket warms cold feet quickly after a long day, and an internal stash pocket keeps a phone or small filter from freezing overnight. Quilt and blanket loops let you extend the system on the coldest nights without committing to a heavier bag.
