my long-time favorite
Now on my second pair of Spy Orbits - love these goggles. I took my old pair and put in a low-light lens, to use for storm days.
1. fit great with a helmet
2. have excellent optical quality
3. are highly resistant to fogging
4. look sick
I have about 150 days of history wearing Orbits, so feel very confident in recommending them. There's no way you should be disappointed with these. Worth every penny.
Only other goggle I liked almost as well was the Oakley Wisdom, but it didn't fit as nicely with helmets.
