Key Specifications

Carbon Fibre Shell

The AT4.0 Carbon uses a carbon fibre shell, which provides a high strength-to-weight ratio. The SM size weighs 1,600 g (plus or minus 50 g).

RHEON Impact Technology

The AT4.0 Carbon includes RHEON as an added safety technology. RHEON is a rate-sensitive material integrated into the liner that stiffens on impact to absorb energy more effectively than standard foam alone.

Fidlock Chinstrap

The chinstrap uses a Fidlock magnetic buckle, which allows single-handed fastening and release. It locks securely under load and opens with a simple pull.

Visor and Field of View

The AT4.0 Carbon provides a 215-degree field of view. The visor is Pinlock ready for anti-fog use. Both a clear and a tinted visor are included in the box.

Shockwave Bluetooth Audio Compatibility

The helmet is pre-configured to accept Ruroc's Shockwave Bluetooth audio system. The Shockwave unit is sold separately and clips into the helmet without requiring tools or permanent modification.
