Multi-impact helmet. Hedkayse: Who has never dropped their bike helmet on the ground and put it back on without anyone noticing as if it were unimportant? What a denial of reality, Freud, a great cyclist of his century often spoke about it... Fortunately, your Hedkayse is designed to last! Its Enkayse™ interior protection technology dissipates shocks of all intensities without deteriorating and its outer surface in bulletproof military nylon reduces friction against the asphalt to avoid any additional muscle injury in the event of an accident. One size to rule them all: A little extra and not the least, it adjusts to all head sizes from 49 to 58.5 cm thanks to its "multi-fit" scratch. Your Hedkayse will follow you everywhere, even if you get a big head. And in the dark, fold it With its clever patented folding, reduce the space occupied by your helmet by 50%, making it very easy to slip into your backpack, messenger bag, front basket, suitcase, glove compartment! Safety AND comfort: Very light, the Enkayse™ material ensures optimal comfort thanks to an astonishing property: at your body temperature and in a few minutes, it fits the contours of your skull! Have you finished your ride? Your helmet will return to its original shape until the next mop. Leather finishes: You'll take a little English class back, right? Are you sure? However... Your Hedkayse is adorned with magnificent high-end leather. You thus swap ballistic nylon for beautiful skin.
