Giro Merino Wool Under Helmet Cycling Cap
The Giro Merino Wool under helmet is lightweight, comfortable and stylish on and off the bike. This cycling cap is thin enough to fit under your helmet and is built with sophisticated panelling to prevent any bunching of fabric.
Compared to many cycling caps the Giro Merino Wool under helmet has a shortened brim giving you better upper peripheral vision without compromising on its ability to block the sun and rain.
