On a damp spring day, when the clouds refuse to budge and a brisk breeze suggests your hands might get cold on their own, reach for the Castelli Diluvio Light Glove. As Castelli's thinnest neoprene glove, the Diluvio is light enough to not leave you sweating and overheated after an easy warm-up climb. The windproof fabric blocks cool gusts on long descents and cold summits, but with such a low-profile design, the gloves can easily be stuffed into a pocket or pack if conditions change.
