Your hands are the first part of your body to slice the air, so aerodynamics is important here too. Castelli have made the back of the glove completely smooth and given it a smooth transition to the wrist.

This glove is made to be used on road stages as well as time trials, giving you an aero advantage with every pedal stroke. With the back in Lycra, the glove is extremely comfortable since it's very stretchy. The soft synthetic palm is thinly padded so that you have a good feel for the handlebar, with just a bit of silicone on the logos to help with grip.

In time trials, notice that the glove is designed to be worn over the long sleeve skinsuit, smoothly transitioning the airflow from the hands to the arms.
