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 Gill™ vents that help regulate temperature during the night, a Blanket Fold™ draft collar that provides tucked-in comfort, an integrated pillow pocket, and a waterproof/breathable footbox to withstand tent condensation. Left-sided zippers on the men’s and right-sided zippers on the women’s styles allow two Fortes to zip together for a double version of these favorite synthetic sleeping bags.
