The Hedkayse ONE is a bicycle helmet made with several innovative design elements that, together, create a multi-impact, foldable, adjustable piece of head protection. For many years I've been stuck between cost and comfort in head protection whilst cycling. Most often this meant that I didn't wear a helmet when I should have, despite more-than-ample reason to take the time to attain the helmet that was right for me. I was extremely fickle. This summer I got to test out the helmet called Hedkayse ONE, and it changed the way I thought about helmets entirely.
