Keeping your hands warm and dry in cold, wet conditions can seem harder than finding an honest man in Congress. Fortunately, for scuba divers, surfers, and those of us who refuse to get off the bike when the weather gets nasty, we have neoprene. Few materials excel at defeating cold, wet conditions with the verve of neoprene. The Castelli Diluvio Gloves are constructed from 3mm neoprene to keep out wind and water alike. A textured grip on the palm makes sure your hold on the bar remains secure at all times. And because exposed skin is unpleasant, whether it's your hand or wrist, the glove's cuff extends far enough to tuck it inside your jacket sleeve. Simply put, the freezing cold day has met its match.
