Dialed in for backpacking adventures, the fully featured Therm-a-Rest Questar 20 sleeping bag delivers 3-season comfort with 650-fill-power Nikwax Hydrophobic Down™ and plenty of cozy features.

Features

  • 650-fill-power Nikwax Hydrophobic Down absorbs 90% less water and dries 3 times faster without using dangerous PFCs
  • With additional room for multiple sleeping positions (W.A.R.M. Fit), means this bag allows for various natural sleep positions while maintaining thermal efficiency
  • SynergyLink™ Connectors let you integrate the bag with a pad (not included) for optimal efficiency and comfort; removable for versatility
  • Zoned down insulation maximizes warmth and saves weight by intentionally placing fill where you need it most
  • Responsible Down Standard certification ensures the down does not come from animals that have been subject to any unnecessary harm, such as force-feeding or live-plucking
  • Shell fabric has a durable water repellent (DWR) to help moisture bead up on the surface
  • Box-baffled construction uses mesh walls to maximize loft and minimize cold spots
  • Toe-asis™ ergonomic toe box rapidly warms cold feet in a pocket of warm down
  • Draft collar, full-length zipper draft tube and cinchable hood help trap heat inside
  • Snag-free zipper; external zip pocket
  • Quilt and blanket loops let you customize your sleep system by layering quilts or tech blankets (not included) for increased warmth
  • Compression sack and storage sack included

Temperature ratings are intended as a guideline to help you compare products, rather than a guarantee of warmth, since many different factors contribute to your comfort while you sleep. Backpacking bags are typically rated for temperature according to an independent testing protocol—currently International Organization for Standardization (ISO) 23537, though some older items followed European Norm (EN) 13537. Testing is based on a person wearing one base layer and a pair of socks, sleeping on an insulated surface with a minimum R-value of 5.38.

Each bag then gets 2 ratings: the Comfort rating is the lowest temperature at which the bag will keep the average "cold sleeper" comfortable, and the Lower Limit rating is the lowest temperature at which the bag will keep the average "warm sleeper" comfortable. Some brands determine their own temperature rating by aligning to the Comfort rating for women’s bags, to the Lower Limit rating for men’s bags, or somewhere in the middle for nongendered bags.
