AML PRO RIDERwrote a review of Giro SPF Ultralight Skullcap on June 8, 2019
Familiarity: I've used it several times
After my dermatology doctor suggest I wear a helmet liner...
this was it . I have a Giro helmet and now the Giro Ultralight Cap.
Feels good, and after a while you don't even realize it's under your helmet. Very nice.
