Oakley JP Auclair Signature Crowbar Goggles - 2008 BCS

The only way to know is to try them on. if you can't find them in a store, you can buy them and if they don't fit you can return them. I have a small head and the crowbars fit me great. I dont know what my face size is, though - there is no standard for measuring face size, as far as I know -One of my helmets is a RED Trace 0.5 (youth) large and another is a Carerra adult small. They fit me well with my Trace, but I haven't tried them with the Carerra yet.

my helmet size is a medium, and this goggle fits perfect, i would recommend the splice though

hat size, im a 7 and im dancing on the edge of medium and large...if ur smaller than a 7 then go for non large fitting goggles

pink iridium i think is better than hi persimmon. and it looks sicker

whats up neighboor!!!!! :-)...i am a huge huge fan of fire lenses because of thier looks, but for performance; i hate to say it but its not the best for our crappy overcast and changing conditions...if your looking at this goggle then the persimmon will be the best, for any other oakley gogs i reccomend h.i. persimmon for washington weather specifically, i have that and it works brilliantly in everything but bright sun

the fire is awesome i have and love

I would go with the HI Persimmon or the HI Yellow. They are pretty similar lenses. The Persimmon will do a little better on bright days while the Yellow will hander overcast/flat light days better. I feel like its easier to deal with brightness than flat light, so I would probably go with the HI yellow, but its up to you.

go to oakley's website and go to their lenses and they'll tell what lens is good for what ever condition you are in

They are not a good all around lens, since they block more light than almost any other lens tint option. If you want a specialized lens for bluebird days and that killer fire lens look, then it might be worth it, but realized that it is almost limited to very sunny days.

The fire lenses block a little more light, making the bright sunny days a little easier on your eyes. The persimmon lens is more of an all around lens. It's made for more overcast days, but still isn't to straining on your eyes on the bright sunny days. The fire lenses are also reflective looking from the outside if this is something you like or want. So if your eyes are more sensitive to light, then they're worth the money, but in my case, I prefer the persimmon lens in more conditions than the fire lens.
