A new approach to freeski and all-mountain helmets. The Four AMID offers a completely new approach to the design of all-mountain helmets. The unique combination of AMID technology and Holo Core offers up to 40 % more impact protection than the current safety standards. In addition to its sleek design, the Four AMID helmet also features a removable liner and goggle clip, so you can ride with a beanie and goggles under the helmet if you want.ConstructionWith in-mold ski helmets, the polystyrene foam inside the helmet is glued directly onto the protective thin outer shell. This makes it light and comfortable to wear. Holo Core is a unique "egg shell" construction. It creates a larger crumple zone for maximum shock absorption.VentilationThe helmet is equipped with a passive ventilation system. This automatically provides ideal ventilation and keeps the goggle free of fogging.Fit systemWith the progressive 360° Fit System you can fine-tune the helmet. Not only to the head size but also to the head shape. Safety standardASTM F 2040, CE EN 1077:2007 CLASS B
