Groppler Zornwrote a review of POC Ventral Spin Helmet on May 26, 2018
Familiarity: I returned this product before using it
but it didn't fit, too small. and in a weird way. The ear straps barely fit over my ears and it was more the tightness of the harness and pads along my forehead that put pressure on my head, rather than the overall shell size.
Anyway, my grape is about 58-58.5 cm for reference, and a medium in all other POC helmets fit perfectly, but this in a medium did not. I'm not willing to go large, I just can't see the point of that.
I'm a solid POC guy and love my Octal X, so I tried on an Octal X Spin as well, and it didn't feel right either, so I'm beginning to think it's the Spin padding/configuration.
I just ordered a Raceday, because 10/10 I will love that.
And a huge shoutout to my gearhead, Connor Johnson, a dude who is an invaluable asset when it comes to online shopping for gear. If you don't have a gearhead yet, or yours lags, give him a shout at firstname.lastname@example.org. My stoke level with him is RAGING.
