One trip to the ER to have gravel scrubbed out of your palms will convince you to never go gloveless. The Castelli S. Uno Glove fits like a second skin so you'll have protection without the bulk. Beginning with the palms, the S. Uno use ultra-suede, a durable fabric that is also pliable and soft. The palms are lightly padded, which provides some vibration protection for your hands while also allowing a secure grip around the bars. The backs of the hands are constructed from micro-mesh, which helps keep your hands cool so you're able to wear them even in the heat of summer. The thumbs feature a debossed micro-suede panel, and they are secured with hook-and-loop tabs at the wrists. Reflective logos have been added for a little extra visibility.
