It's perfect for autumn, spring, and early winter when you need warmth without bulk. The windproof, waterproof front panel on the back of the hand offers protection from the elements, while the Thermoflex cuff provides warmth and light compression. The cuff itself is moderately long and has rolled hems that make it compatible with any knit cuff or jacket. Castelli's thin Ultra Fleece lines the inside of the glove for added comfort and insulation. Castelli chose a synthetic suede palm for its durability and waterproof qualities. The palm surface, index, and middle fingers feature a textured silicone print for excellent grip and control in all weather conditions. The thumb, index, and middle finger tips allow you to handle most touchscreen swipes needed to interact with your phone, bike computer, or any other device while riding. Suede microfiber is applied on the thumb for a softer, easy-to-clean surface.
