Have you ever had goggles that didn't fog up while hiking? If so, let me know which. I never hike with goggles (even sunglasses fog up hiking)
Im in the same boat as you, I sweat profusely when I ride hard. My goggle experience has been a work in progress, but I arrived at Smith IOX after owning many different brands. Oakley, Dragon, Von Zipper, Hoven and feel the quality of lenses and venting are best for me with the Smith goggles. I used to have to carry extra oakley lenses just to be able to see. Broke too many to justify owning oakley. Don't have that problem anymore.
