b/c oakley's are way too small
I am completely tired of the narrow fitting Oakley goggles. Thankfully they are coming out with the "canopy" goggle for 2013. Regardless, I bought the SPY's on a whim and am more than happy with the fit and function. I wear a Bern Baker helmet and these things fit so weil over or under the helmet. The frame is huge which is a bonus for those with a wider face, no necessarily "asian" either (oakley). Yea they will be pretty big on the scrawney people of the world but that is no reason to mark these goggles down.
Finally, little to no fog build up, comfort all day. just bought my second pair. Can't wait!!
