The Castelli Boa Glove has been designed for the Cannondale pro riders who have to race in ridiculously cold and rain-soaked bike races. When racing in cold wet weather, past professional rider’s hands would go numb making it hard to get their gloves on or off to eat, adjust radio, and change gloves and jackets. The Boa was made to ensure racers don’t ever have to face these bad weather conditions. The Boa is easier to open and therefore easier to get on and off so you don’t face any of the above problems including making an emergency call or taking a pit stop. Castelli developed the OutDry technology to make the Boa totally waterproof. The gloves come up the wrists so your sleeve completely covers them. No area of your skin is exposed to cold, wet weather. The fleece lining traps body heat so your hands stay warm in freezing weather. Silicone pattern on palm gives good handlebar grip.
