My favorites are the Smith & Wesson Magnum. They are inexpensive (less than $7 a pair) and they are good quality. They have full coverage - I don't feel any wind coming in even when I turn my head from side to side doing headchecks at intersections or whatever. Their service is great - I ordered from safetyglassesusa and my order was there in 3 days. (No, I don't own the company!)

I have both the clear and the smoke leses, and I use the clear ones most of the time. They are the fog resistant ones, and when they say 'fog resistant' that sure doesn't mean 'fog proof'. But the price difference is just 40 cents.

I live in Seattle myself, and I use them all the time for flying down hills without tearing up.

Cheap, adjustable, good quality...
