It takes minimal time to get used to, and proves a little more comfortable on the chin than the usual clip.Integrated MIPS technologyIn-Mold polycarbonate shell with EPS linerFull Hardbody shellRoc Loc Sport MIPS fit system18 ventsQuick-dry paddingRemovable visorReflectivityUniversal Size - 54 - 61cm
