The idea for the Castelli Boa Winter Glove came in the ridiculously cold and rain-soaked 2014 Milan-San Remo. Castelli’s pro riders had numb hands and couldn’t get their gloves on or off to eat, or to change jackets or gloves. Se they worked with boa to make a glove that’s easier to open up and thus easier to get on and off. Castelli built it with OutDry technology for waterproofness and made it come high up the wrist so your sleeve can completely cover it. the easy on/off is also handy when you have to interrupt your ride for an urgent phone call or text message.
