Classic mummy-bag design isn't ideal for the 70% of people who sleep on their side. The men's NEMO Forte 35 sleeping bag adds room at the elbows and knees for 3-season, side-sleeping comfort.


  • Featuring 80% postconsumer recycled content, PrimaLoft® RISE insulation delivers maximum warmth with less weight and water retention than conventional synthetic insulation
  • PrimaLoft RISE insulation increases heat retention and compressibility that matches or beats 650-fill-power down—ideal for 3-season camping
  • Unique Spoon™ shaped bags offer more room at the elbows and knees, allowing side sleepers to shift positions comfortably throughout the night
  • Thermo Gills™ extend the temperature range on milder nights: Unzip them and let heat out without letting cold drafts in
  • Blanket Fold™ external draft collar and a full-length draft tube provide tucked-in comfort and temperature regulation
  • Waterproof/breathable footbox withstands tent condensation, keeping feet warm and dry
  • A fabric set of 30-denier ripstop polyester and 20-denier nylon taffeta offers an ultra-plush sleep experience
  • Durable water repellent (DWR) finish on both shell and lining fabric resists moisture
  • Full-length double-slider #5 YKK zipper with zipper plow makes getting in and out of the bag a breeze
  • Integrated pillow pocket allows a jacket, extra clothes, or Fillo™ (not included) to be stuffed into the sleeve opening for secure, elevated support through the night
  • Opposite-sided zippers on men's and women's sleeping bags increase versatility by allowing them to be zipped together into a double sleeping bag
  • NEMO offers a lifetime warranty on this bag


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.
