Ice Lite
An integrated composite exoskeleton unifies a super light three element construction for extra strength and unparalleled ventilation. The Exoskeleton is integrated into the in-moulding process allowing structural performance way beyond established standards. Deflectors are included to accelerate ventilating airflow.

Gel 02 Padding
The world's first use of hypo allergenic and thermo-stabilising gel padding in a cycle helmet, providing totally incomparable fit and comfort. Replacing traditional fabric pads with gel keeps the head cool thanks to the natural capacity of gel to stay cool and dispel sweat when in contact. Security and fit is also improved as gel adjusts to the form of your head.

Head Contact Surface: 20
Less than 20% of the area covered by the Helmet is actually in contact with it for a feather light, unobtrusive feel.

Integral In Moulding Shell Construction
Fusion is carried out on the external surface of the helmet for reinforcement and longevity.

Adjustable Kevlar Straps
An ultra light, strong and durable material that guarantees safety, comfort and breathability.

Safe-T Smart Closure
A micrometric occiptial retention system featuring both horizontal and vertical adjustment to distribute pressure on a broader surface to increase performance and comfort.
