When your training plan pitches you against freezing cold, your hands will be the first to feel the effects. Fortunately, for scuba divers, surfers, and those of us who refuse to get off of the bike when the weather gets nasty, there's neoprene. The Castelli Diluvio Deluxe Gloves were designed with the sole purpose of keeping your hands warm. Few materials excel at defeating the cold as proficiently as neoprene. Accordingly, the Castelli Diluvio Deluxe gloves were constructed from 3mm neoprene. This way, the gloves insulate in order to keep out both wind and chills. Textured grip on the palm makes sure your hold on the bars remains secure at all times. And because exposed skin is unpleasant, whether it's your hand or wrist, the gloves' cuffs extend far enough to tuck it inside your jacket's sleeves. Castelli included its classic Scorpion graphic on the back of the hand, and a terry nose wipe strip on the forefinger to finish the gloves. It's important to note that, although neoprene will keep light drizzle off your skin, it's not waterproof.

The Castelli Diluvio Deluxe Gloves are available in the color Black and in the sizes SmallMedium, LargeX Large, and XX Large.
