When designers at Castelli set out to add a glove to the brand's Perfetto lineup, they knew they had to get things just right. After all -- the Perfetto name draws quite a lot of attention, and comes with a high reputation. Fortunately they pulled out all of the stops with the Castelli Perfetto RoS Glove, packing in all new materials, minimal seaming, and just the right amount of cushion to keep you on the road, come rain or shine. The gloves begin construction with new GORE-TEX Infinium fabric that offers water and wind protection on the outside, while a fleece layer inside traps heat and ushers away sweat. The gloves provide ample warmth, despite being deceptively thin, so you can maintain mobility and dexterous control of your shifters and braking. The palm packs in Castelli Damping System, or CDS for short, strategically placing padding where your hand receives the most vibration from the road, aiming to reduce fatigue and elevate comfort while you ride.
