I have no idea. I just purchased mine from Blowsion. I love it.
If you want high dollar they also sell a carbon fiber Giro. Very trick.
I looked for a helmet prior to Tona. Found one I simply fell in love with…the brand started with an “S”. :dunno: It was a children's, male, small, and it still didn’t fit properly, so he wouldn't sell it to me thankfully. He ordered an xs…telling me it arrived after the meet. It was between $3-400.00...I don’t recall exactly.
It was beautiful, black with a faint purple design, but best of all it felt so different from all the others…it felt GREAT (and light). It had two safety certifications. The one I have now is certified, but is cheap and feels no where near as good (plus it probably doesn't fit properly either...now that I've been taught). I never did go back to look at it. I still want to, but after reading this thread with all the cheap prices…I just don’t know. I want it though.
