ULTRA LIGHT HELMET - You no longer have to choose between lightness and comfort! This new Kong helmet, thanks to its wide internal padding, provides maximum comfort in just 210g. The molding technology of the external polycarbonate layer, with internal high density polystyrene, provides exceptional shock resistance and an incredibly reduced weight. Certified to CE EN 12492 for climbing, mountaineering and ski-mountaineering. The Leef is a great example of structural minimalism. The material that gives it strength is minimized, and present only where necessary. That is what we had in mind during the development of this helmet. Wear it, you will forget you have it on
