Helly Hansen LIFA base layerHelly Hanson's LIFA® fabric has been keeping active people warm, dry and comfortable since 1970. The proprietary yarn technology was one of the first to effectively move moisture away from the skin, keeping you feeling fresh whatever the conditions. 

Instantly recognizable by the striped sleeves, LIFA® base layers are surprisingly lightweight but they do a great job of keeping you toasty, even on the coldest days. Flatlock stitching means you'll avoid the dreaded chafe, even if you're wearing a backpack.
