Leatt ADV 8.5 V25 Helmet Kit

The ADV 8.5 helmet kit provides premium protection and performance for adventurous riders. It is constructed from a three layer composite matrix which is a lighter and stronger construction than a polymer shell. Furthermore, it features Leatt’s patented 360º Turbine Technology, where the energy absorption of the turbines helps reduce the low-speed impact energy to the head and brain. The helmet is fastened with a secure DD ring buckle. An ADV helmet is different to an off road helmet, designed to minimize drag and lift for a smoother ride at higher speeds when on roads. It is quick and easy to transition to off-road use, with an extra wide eye port compatible with off-road goggles. Adjustable vents cater to all riding conditions, keeping you cool and comfortable. Depending on rider preference, the visor is completely removable at the twist of a clip, allowing you to set your helmet up to your liking.

What really makes this helmet stand out from any other is the kit. Included with the helmet in the kit is a photochromic and clear visor, 4.5 goggles and a Pinlock MaxVision anti-fog shield. Photochromic shield technology allows the visor to lighten or darken depending on the amount of UV light. This way, you’re always riding with crystal clear vision. 4.5 goggles provide additional eye protection, and the Pinlock 120 MaxVision XLT prevents fogging by creating a thermal barrier between the inside and outside of the lens.
