As the name suggests, Castelli designed the Arenberg Gel Glove to handle the roughest stretch of cobbles of the Paris-Roubaix. This glove features generous gel padding in the palm to absorb vibration and prevent fatigue. Castelli covers the gel inserts with a durable AX Suede fabric that also delivers a superb grip. The back of the glove uses a breathable polyester mesh to keep you cool and comfortable, and an adjustable hook-and-loop closure secures the fit.
