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.
