Castelli Diluvio C Long Finger GlovesConstructed from 3mm thick neoprene Castelli based the Diluvio off the gloves used for scuba diving in cold conditions. Just like a wetsuit, your body heats up moisture in the glove and keeps you warm. Like many of Castelli's gloves, the Diluvio features an extended cuff and a grip print on the palm. Ideal for riding hard in milder and rainy conditions the Diluvio is an inspired design that proves how simple ideas can yield big results.
