The Shimano S-Phyre Sleeveless Base Layer is engineered for riders who demand maximum performance and comfort in all conditions. Designed to sit next to the skin, this technical base layer helps regulate body temperature by efficiently wicking sweat away from your torso, keeping you dry when you are working hard on climbs and preventing chills on long descents. Its sleeveless cut reduces bulk under tight-fitting jerseys and suits, making it ideal for road, gravel, and cross-country racing, as well as fast training rides.
Constructed from lightweight, stretchy fabric, the S-Phyre base layer offers a close, second-skin fit that moves with you on the bike, minimizing chafing and hot spots. The seamless or low-seam design commonly used in this type of garment enhances comfort under bib straps and around the shoulders. Breathable mesh zones are typically placed where you heat up most, helping moisture escape quickly. Whether you are riding in cool spring air with extra layers or in peak summer heat with just a jersey on top, this base layer adds a refined level of comfort and performance to your kit.
