The Therm-a-Rest Parsec zero-degree bag has retired my long-time winter bag thanks to its highly compressible 800-fill Nikwax Hydrophobic Down™ that apparently absorbs 90% less water and dries three times faster than untreated down. That means warmer nights out backcountry skiing, snowshoeing, or just winter or early spring camping when sweat and moisture can wreck the warming capacity of an old-school, untreated down bag.
Other cool features include an external zippered pocket, a certified 100% recycled nylon shell, an anti-snag zipper that makes getting in and out easy, a down-lined foot pocket for warmer toes, and straps to keep your sleeping pad connected to your bag. Compression/storage sack included.
MSRP: $489.95 – $569.95. Thermarest.com
