Delivering 3-season comfort, the Klymit 20F full-synthetic sleeping bag employs pillowy synthetic fiber insulation that keeps you warm and comfortable all night long.


  • Outer fabric has a durable water repellent (DWR) treatment to protect the insulation from moisture that can impede thermal performance and add weight
  • Stretch baffles keep warmth next to you, and allow you to sit up, stretch and freely cross your legs without unzipping your bag
  • Built-out footbox offers plenty of comfort where its needed most
  • Mummy hood with draft collar and drawcord reduces draft
  • Closeout


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.
