M Frame. Flak Jackets are good. Radarlocks. Half Jackets are popFram, so you'd probably seen a bunch of them.
I agree With Chrometip, polarized are not worth it in my opinion.
No white frames!
I use Racing Jackets for Softball. Bought them for riding MTB, but they work good and the interchangebale lenses rock. So I can choose what I need for the time of day. Use them for the range too, since I have the High Intensity Yellow lenses. Just picked up a pair of Fast Jacket XL's, that I may switch to the Softball pair. Those interchangeable lenses man, they're the goods. Wear Fuel Cell for my daily, larger version of the Gas Can. So make sure if you carry a pair with interchangeable lenses, you carry some of them as well. The lenses JBO said are the ones to carry for sure.
