Seventy percent of people sleep on their side, yet mummy bags are not designed to accommodate this. Forte™ has been updated with Primaloft’s, lightweight, ultra-lofty and supremely resilient RISE insulation featuring 80% post-consumer recycled content. Forte’s classic Spoon™ shape provides a generous cut at the elbows and knees so side sleepers can shift positions comfortably throughout the night.

These 3-season backpacking bags are loaded with features, including Thermo Gills™ that help regulate temperature during the night, Blanket Fold™ that provides tucked-in comfort, an integrated pillow pocket, and a waterproof/breathable footbox to withstand tent condensation.


  • 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
