Can tell the quality. careful not to undersize 'em. - Revision Eyewear Sawfly Eyeshield Basic kit

Let's get sizing out of the way. I thought I had an average-to-smaller head size so I bought Regular. Just measured my hat size...borderline 7 3/8. I can feel that slight, annoying pressure on my temples. Maybe I should have bought the Large. Please google how to check your own hat size accurately...don't guess like me.

As for the product...they are great. While I walk around in Maui Jim sunglasses, I plan to buy more Sawfly lens for working in the yard, bicycling, and more...so I can toss my 12-yr-old Oakley M-Frame Pros. I'll only miss the vented M-Frame lenses but, I can see why Revision may not have vents for protection reasons.
Pros: This is the lense I thought someone would surely be making.
Cons: Sizes like a men's undershirt...smaller than we'd hope. Also, no vented lenses for airflow while I'm outside in the humid south.
