Our collection of comfortable, breathable men's cycling base layers regulate moisture and temperature, so you stay drier in summer, warmer in winter, and focused on your surroundings. With merino, Polartec™ fabric, sleeveless, short, or long sleeve options, our men’s base layers are made to move from super soft natural and performance fabrics for varying conditions and, when worn with any of our cycling jerseys, cycling bibs, cycling gilets or cycling t-shirts, are an essential part of every serious cyclist’s wardrobe.
