YAKKAY "SMART ONE" is a new smart design that differs by its rounded ear straps and adjustment buckles in polished stainless steel. But the real difference shows when one of the many different covers is attached to the helmet - It changes its characteristics from those of a helmet to those of a hat and becomes an accessory to your outfit. You can adjust the helmet to your head with a number of adhesive foam circles which have the added advantage that air can circulate between them. When you are riding your bicycle, air will be pushed into the helmet, and pleasantly cool down your head. In addition, your head will stay dry in rainy weather, as the covers are designed without open holes. The helmet fully meets the European CE standard (EN1078).
