For me it a pair of Costa Del Mar Brines. Had these puppies for 5 years now and still love them. Just curious if there are other brands out there that you've been impressed with.
LE/Military issue Oakley Flak Jackets with polarized blue lenses. Basically they have a subdued "O' on the side and no wording on the front. Love these things. I haven't found a single thing yet that will cause them to fall off. Super light and once they're on they stay on regardless of sweat, temp or activity.
