Swim Goggles

I wear TYR Nest Pros and LOVE them. I was a Kaiman wearer as well but found that they were leaking a lot and not as comfortable after awhile and find the Nest Pros to be a better fit. They still have a great field of vision but don't cover as much of the eye area, which IMO leads to a better seal and less leaking. I have the smoke gray for outdoor and racing and pale blue for indoor.

You should try on the Aquasphere Kaiman before you dive in. They're a solid pair of goggles, but I've noticed that Aquasphere's "low-profile" means that the lenses are much closer to your eyes - in fact, they virtually hit your eyelashes (they will if you have long eyelashes). This also means they fog up much faster than other goggles. For me, this aspect outweighs the larger lens size.

The Speedo Vanquisher has a more bulbous frog-eyed appearance, with the lenses pushed away from your eyeballs. I prefer this, as it fogs a lot less for me. The Aquaspheres are easier to adjust, and felt like they fit better in the store, but for me, the Vanquishers performed better in terms of nonleakage and nonfogging (by a lot) in the water. (I own both, and now only use the Speedos.)

Despite the antifog treatment, they will all fog if you use 'em straight up.

The spray-on stuff does prevent fogging, although it can slightly distort the view since it's like a detergent. (You'd get really annoyed with the view if you used these on your cycling glasses.)

At least for me, the Speedo Vanquisher fogs much less than the Aquasphere Kaiman, likely because of the proximity to the eye.

I've had good luck with my TYR's.  They just seem to fit my face better than others.

I have a couple of blue pairs for the pool and a clear pair for racing (6:30AM starts and tinted goggles don't work well together).
