The Windstopper Base Layer Shirt provides insulation and wind protection for windy conditions. It features a WindStopper membrane on the front, shoulders, and kidneys, with a polypropylene/elastane blend fabric for moisture management and stretch. The short-sleeve design allows for versatile layering. Flatlock seams reduce friction, and the extra-long back offers good coverage and comfort. The form-fitting, soft fabric delivers a comfortable next-to-skin feel.
