Castelli Core Seamless Short Sleeve Base Layer
Stay completely focused when riding in mild to warm conditions. The Core Seamless Short Sleeve Base Layer has a totally seamless design, so there will be no niggling discomforts, even under race-fit, aero jerseys.
The base layer is made from a mix of polyester and polypropylene to create an exceptionally stretchy fit, so that your freedom of movement will be unencumbered. The blend of yarns is also soft to the touch, warm, and high wicking for when the tempo increases and your body is working harder.
Light weight sections on the side and back reduce the bulk where you don’t need quite so much insulation and help to give the base layer its almost unnoticeable feel when you’ve got it on. A wide neck sits easily under short-collared jerseys.
