When maximum insulation is needed, reach for the Drynamo Turtleneck Base Layer. It shares the same moisture-managing textile and body-mapping ventilation design as the rest of the Drynamo Base Layer family, but with a taller neck and long sleeves to keep the cold out and the warmth in. Equally appropriate to be worn skiing or snowshoeing as on a winter ride with a diamond-shaped mesh vent across the upper back to keep the air moving. Thumb holes ensure the sleeves won’t bunch up when other sleeves enter the picture.
