Variant Giro Radix prilba, Mat Chalk

Bought as a gift for a friend for whom it was big, in the end I kept it for myself, even though I have a FOX, this one is more suitable for shorter, less demanding trips.

Super ventilated and so light, nice that I basically wear it all the time. I still have it on my head? I was not mistaken...
