GMax HH65 Source Naked Helmet


Half helmet with a drop down sun shield and a visor? Yes, please!


GMax HH65 Source Naked Helmet

The HH65 Helmet packs a long roster of features into a slick half-helmet shell that is ready for the open road. This low profile lid delivers V-twin style while concealing a dual-density EPS liner and earning a DOT certification. A tinted drop down sun visor slides into action when the sun hits eye level. This tinted shield can be swapped without tools for a clear visor (included) for UV protection and to shield the eyes from the wind. A low-profile sun peak provides some additional shade from overhead sun while adding to the classic appearance.

Internally, channels in the injection-molded EPS help pass air over the rider’s head, and a removable / washable liner using Coolmax Core Technology helps regulate heat as it pulls perspiration away from the rider and facilitates evaporation. The polycarbonate shell is a continuous, uninterrupted form with either black or polished rivet hardware for a look that pairs well with any ride. An included neck curtain can be easily added or removed to regulate temperatures further and help shield the rider from wind bast. This snap-in neck curtain also features speaker pockets to make Bluetooth installation easier (Bluetooth sold separately).

The HH65 Helmet shares many of the same features found in the GM65 Helmet. The HH65 Helmet, however, uses a quick-release ratchet strap closure with micro adjustment instead of a double D-ring buckle.
