The Women’s Forte 35 Regular sleeping bag is ideal for the UK’s summer conditions. Filled with PrimaLoft RISE synthetic insulation: the resilient material will continue to perform if it gets wet. Use the Blanket Fold collar to trap extra warmth; if it gets too hot, the Thermo Gill vents let you release body heat. Designed around Nemo’s Classic Spoon shape, the Forte is ideal for side-sleepers. Generously cut at the elbows and knees, you can lie on your side without being constricted.
