Therm-A-Rest – celebrating their 50th anniversary this year – is one of the most trusted names when it comes to cozy sleeping arrangements in the great outdoors.

This spring, Therma-A-Rest expanded its award-winning ParsecTM collection of light sleeping bags to take on the coldest of temps in total comfort.

Added to the line up are two additional temperature ratings: both a 0 and 32-degree and the existing Parsec 20 has been updated as well. Each bag in the collection boasts an all-new design to keep you cozy in frigid weather, plus an updated 100% recycled shell and liner. Although just as durable as its predecessor, this recycled nylon is softer and light for optimum comfort.

Other notable features include sustainable 800 fill Nikwax Hydrophobic DownTM that absorbs 90% less water and dries three times faster, the Toe-asis Foot Warmer PocketTM, heat-trapping draft collars, a cinchable hood, snag-free zipper, and external zip pocket. Compression and storage sack included.

The Parsec 0 weighs in at 2 lb 6 oz; the updated Parsec 20 is 1 lb 12 oz; and the Parsec 32 comes in at 1 lb 8 oz.
