Well I usually just tool around in a pair of Randolph Aviators

When on long runs or alot of highway driving I picked up a pair of Wiley-X from my local Harley store. These have the foam inserts so my eyes don't dry out and everything gets all fuzzy.
The nice thing about them is that they come with two shades of lenses and you can just pop them out and change from clear to dark. They also come with a headband and nice case. Cost was about 100.00

However, now I just got a catalog from
http://www.directsafety.com
and they have a goggle with foam lining and headstrap. In clear and gray only.
"Polycarbonate lens with DX anti-fog anti-scratch coating. Soft foam backing seals out dust. Complete with adjustable elastic headband. Meet ANSI Z87.1-1989"
Only 9.50 each!!!
