All of the above, plus. of course, foldable, but that didn't start with the letter c. So wonderful fro getting around Washington DC and being seen and so safe day and night.

Hello,
This is an incredible folding bike helmet.
Well-designed and provides good head protection.
I'm very satisfied with this bike helmet.
Thank you for this ingenious innovation.
Sincerely.

It's sleek, it's ideal, and it's comfortable to wear!

Good quality build, for perhaps too much money, only thing I would add is more color choices, like the original one

where to begin? I travel often and to cities where rentable city bikes are abundant, however, also have helmet wearing requirements. to collapse this helmet down to approx. a third of its original size is pinnacle to my able to bring a helmet and solve that riddle.

having additional lights on my person gives me added security about traveling on roads I am not as familiar with. I am so grateful for the added be-seen lights this helmet affords me

I own a folding bike, and so having a folding/collapsing helmet leaves me feeling like I'm a secret agent (I'm a dork, I know)

I love this helmet so much, and trust it as a better helmet so much, I purchased one for my partner and put their safety in the hands of FEND.
