The Core Seamless Base Layer jersey from Castelli is ideal for slightly colder rides due to its ability to provide warmth while remaining lightweight.

Many base layer jerseys are made of nylon or lycra, which can end up feeling wet after a long ride. This issue is addressed with the blend of 84% polyester and 16% polypropylene, providing a soft, warm, and extremely comfortable fit.

Additionally, the jersey features as few seams as possible, enhancing overall comfort.
