I am about to buy a helmet, either a Byerly or a Pro-Tec. I checked the sizing charts and measured the circumference of my head, but I am border line between two sizes. Can anyone who has either one of those helmets tell me what size they got and how it fits, the circumference of their head or their hat size in baseball caps. <BR>Thanks for the help.

7 3/8 Large Pro Tec Ace fits perfect. Get One. It saved my eardrum last weekend.

I would go with the Pro-Tec Wake helmet because it has an adjustable head gasket inside. Get the biggersize and you can adjust it smaller.

I ordered 2 sizes from REI when i got it and chose the instore pickup. I opened the box right there and returned the one that didn't fit. That's what the REI guy on the phone recommmended even.
