The original technical Helly Hansen base layer has never looked better. We took inspiration from the iconic sailor strip for this long-sleeve crew. Our technical base layer provides breathable warmth, moisture management and comfort during any aerobic activity. It’s ideal for sailing, hiking, training, climbing, skiing and more.  We've been excelling at HH LIFA® base layer technology for 40 years. That’s why our base layers are the go-to choice for professional athletes.
