From exhilarating deep snow descents to relaxing forest hikes, the revamped 260 Tech Long Sleeve Crewe is a versatile midweight baselayer and the perfect foundation for any winter layering system. Made from 100% merino jersey, the Tech LS Crewe offers the insulating, temperature-regulating, and odor-resistant properties you need for active days and long tours. Gussets under the arms, forward-placed side seams, and offset shoulder seams allow for freedom of movement and prevent chafing during high-intensity activities or while wearing a backpack.
