Castellis Prima gloves are manufactured with a lightweight Coolmax yarn. Essentially this material keeps your hands warm while also wicking away moisture caused by sweaty palms. in addition the gloves feature silicone grip across the entire palm & fingers increasing dexterity as you work your grip in the cold. These are surprisingly grippy gloves even when rain or dew has made your bar tape wet. The grip pattern is the reason that the gloves have become a favourite for cyclocross riders & mechanics alike. Being able to pick up & manoeuvre your bike by the bars or the top tube & not have it slip in your hands is paramount to cyclocross success. These gloves accomplish just that. Finished with a long knit cuff the gloves slip easily under your jacket without adding bulk. The conductive thumb & forefinger pads make smart phone/satnav/touchscreen operation a piece of cake
