I have used these goggles for over 25 years - maybe longer - ever since I first discovered them. The shape of the lenses fit my face perfectly and I don't have leaks to stop me from doing my laps. These are "my" goggles.
I would like to be able to get a replacement strap and connector because they do wear out. I know they are available somewhere because I have bought them before. Baracuda makes super good goggles.

They're just about leak proof after fiddling with the nosepieces and strap.  It takes some getting used to since the field of vision is so much smaller than my Aqua Sphere Kaiman Googles.  I was looking for goggles that didn't leave any rings.  So, these don't leave rings. My eyes still have a goggle eye look.  The B300 make my head feel like there's a lot of stuff on it. That's what I have to get used to as well as adjusting to the "blinkers" effect (like race horses).  The antifog only lasted for 1 3 mile swim.  Now, I need to use the spit method.  Somedays my head doesn't want to deal with the B300 so I make sure I bring the Aqua Sphere Kaiman's with me too.  Today I wore them for 2 miles and switched to the Kaiman's for the 3rd.  I prefer the Kaiman's to the B300.  The Kaiman's rings aren't as prominent as other goggles that I have worn as long as I apply them to my face below the socket bones.

I've been lap swimming regularly for 30 years and these goggles are the best I've found.  Comfortable, no racoon eyes, and they don't leak.

I am a regular lap swimmer.These goggles have been very difficult to adjust, so that they do not leak. I have tried each of the 3 nosepieces and still have leakage issues. If I make them so tight they are uncomfortable, they do not leak. But the reason I bought them was for comfort and to avoid goggle lines. They only leave marks on my nose. I am still hoping to get them so that I can be comfortable and have no leaking.

The best googles ever -- no pinching and no lines etched into your face for hours after you've swam. Plus they are easy to fit to your face.

Very adjustable and comfortable

Highly recommended
