very nice swim goggles - do not fog up!

Haven't had any major problem reported by others.  Some slight leaking that I can usually fix by readjusting and pressing more firmly onto my face.  The ocular pieces are a bit small, and thus not that comfortable.  But they look really cool on!  Also they smudge easily, and that can be difficult.

Great clarity but fogs up after a few uses.

These goggles are comfortable and distortion-free.  You cannot blame a missed turn on these goggles

a little hard to adjust but other than that they work great

I'm a triathlete and use them for training swims and races. I love the fit and they do not leak. The thing I don't like is that they limit your vision to what's directly in front of you. It gives them a strange feel when swimming in a clear pool.
