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.
