When the weather gets cold, it's easy to opt out of riding in favor of a warm couch and a good book. With the Craft Women's Long Sleeve Active Extreme Crewneck Base Layer in your cycling wardrobe, you don't have to worry about getting cold out on the road. Built to serve as the first layer under a jacket or jersey in temperatures ranging from about 25 to 55 degrees Fahrenheit, this base layer provides cozy warmth against the snowy cold. As one of the most versatile layers in Craft's base layer collection, the Active Extreme was constructed using a thin, lightweight, and elastic micro polyester. This breathable fabric was channel stitched using a combination of two technical fibers. The first is an exceptionally soft 'hexa channeled' fiber blend that rests against your skin, which begins the process of pulling moisture away from your body. This blend of fibers works in conjunction with the hollow fibers on the outer layer, providing insulation to your core and aiding in moving that moisture to the next layer. The materials work together to keep your body dry, comfortable, and smelling fresh throughout your most intense training sessions. The highly elastic fabrics used to construct the Active Extreme provide a smooth, anatomical fit that moves with you underneath your additional clothing layers. The panels were joined using curved flatlock seams to eliminate abrasion and friction. Contrasting stitching lines the top's right shoulder, and subtle logos adorn the neck and sleeve.
