Let the Extreme Polar Long Sleeve Shirt protect you! Made by Northwave Lab in collaboration with POLARTEC®, it offers maximum warmth in extreme weather conditions. POLARTEC® POWER DRY® fabric is recycled and consists of two different surfaces, one that removes sweat from the skin and the other that dries quickly. The garment is highly breathable and is ideal as a winter or mid-season intermediate layer. Three large rear pockets with reflective insert ensure visibility even on cloudy days. Iridescent reflective logo on chest.
