The warmest synthetic insulation for the lightest weight. The Core Liner is designed to extend the warmth of your sleeping bag and double as a blanket when you arrive in camp. A large opening and 3D hood allows you to sit fully inside the bag but with your arms free, utilising the super stretch of the PrimaLoft® ACTIVE 75g/m2 weight fabric. The 3D hood can be drawn in around the face when maximum warmth is required. PrimaLoft® ACTIVE blurs the line between wadding insulation and fabric; PrimaLoft® ACTIVE loosely weaves PrimaLoft®’s industry-leading insulating fibres through a fine polyester mesh. The resultant structure is warmer and less than half the weight of a conventional fleece product – Down like performance when dry whilst also still performing when wet.
