Sandbox Profile MIPS Helmet The Sandbox Profile MIPS Helmet takes the familiar shape of the Classic and refines it with a lower-profile, lighter fit for skiing and snowboarding. A polycarbonate shell and EPS liner provide lightweight protection, while the MIPSA(R) Protection System helps reduce rotational forces during certain angled impacts. Sandbox&';s Fit System helps dial in the fit, and a magnetic chin buckle makes fastening easy even with gloves on. Removable ear covers, a vented comfort liner, audio pockets, and a removable goggle clip make it easy to customize for changing conditions.
