I use these for swim training as well as triathlons.  I like them because of the single head strap that splits in the rear as well as the high nose piece that does not sit on top of my nose.  They are very comfortable and seal excellently.

I've used these TYR Technoflex Vision goggles for about 2 weeks now and am pleased with its performance.  A notable improvement over the Speedo Hydrospecs that I was using before.  The TYR leak less - actually, they haven't leaked at all, yet - and are more comfortable.  Comfort is important to me, because I swim for an hour, and these goggles don't distract me with discomfort as others have.

ultimately comfort and seal are most important.  after then is vision, etc, etc.  It is reasonably comfortable and seal is marginal.  Why do companies have so much difficulty making googles that seal?

i swim 1 or 2 days a week in the pool and these goggles last a long time and fit really well for hour long swim sessions. These are my 3rd pair. The first I ever owned broke the strap when I tried to adjust it, right out of the box. TYR overnighted me a new strap free of charge to replace it. Great product, great customer service.

they actually fit my face!
