Item # KSK000A

We give it a 10.

The trifecta of the perfect helmet is comfort, fit, and above all, safety. But as we're sure you'll agree, rarely are all three achieved. The Kask Dieci Road Helmet not only goes above and beyond this criteria, it adds a bit of fashion sense with clean, classic lines.

The most important of the three features is, of course, safety. To this end, the Dieci is built with an internal strengthening frame. Because the expanded polystyrene shell has been molded around the frame, if an impact occurs, the helmet will not break into pieces. Effectively, the inner and outer shells of the helmet have been joined to ensure better shock absorption. Kask's Technology MIT has added a layer of polycarbonate to the entire shell, including the base ring and back, which further increases strength.

Linked directly with safety is fit, because if your helmet doesn't fit well, it won't properly protect your head. The Kask Dieci was designed with its proprietary up-down system. This adjustment utilizes a double pivot design that cradles the back of the head with vertically adjustable straps. They are then tensioned with a central ratchet wheel. The helmet is able to micro-adjust to such a wide variety of head sizes, in fact, that it only comes in one size. Soft, non-slip, Coolmax pads were added to ensure a secure fit. They were constructed from Kask's 3D Dry system, which draws perspiration away from the head. Aiding in keeping your head cool and comfortable are 19 large air vents. These have been arranged to optimize airflow as well as aerodynamics. Finishing off the Dieci is a padded, non-allergenic, synthetic leather chinstrap and reflective stickers for low-light visibility.

The Kask Dieci Helmet comes in one size and in the colors Anthracite, Rosso, Nero, and Bianco.
