I've been swimming for 25 years.  The Barracuda goggles are, by far, the best I have ever used.  The round shape fits well, the foam padding is water tight, and they are easily adjustable.  These goggles leave no marks on the skin, no racoon eyes.  Best of all, they are COMFORTABLE.

Comfortable, no racoon eyes, they work.

Better not leaving goggle lines.

These are the best goggles.  No rings around my eyes, and the water is kept out too!

Bought them in an attempt to reduce the raccoon look I'd have for most of the day after my workout.  I'm still trying to get my new pair to fit properly (and not leak).  No doubt, they feel more comfortable than the more race-oriented googles I've used in the past.  I got these to simply do laps.

I have been swimming for exercise for 33 years and have found that Barracuda swim goggles are the only ones that really keep the water out and don't create pressure marks around my eyes.  I haven't been able to find them in stores for a lot of years now, but refuse to use inferior goggles so I order the Barracudas (the standard model is my favorite) online.
