When we're spending long hours in the saddle, it can be nice to enjoy a little extra comfort and sun protection. This barely-there cap is designed to fit easily beneath our helmet without compromising the fit, where it then acts as a breathable layer that wicks sweat away from our head. As an added bonus, Deflect UV 50+ protection defends our face (thanks, brim!) and head-because sometimes those ventilation point on our helmet act as a window for the sun.
