I've been using TYR googles for the last few years, but they keep breaking about every 9 months and finally TYR told me to basically F off, they were tired of providing me warranty replacements.  I might have a skinny nose so a lot of fixed width googles will leak on me, but these puppies didn't leak and were so clear.  I seriously saw so many new things in my pool I had never seen before.  I'm sure like all things in chlorine they will eventually break, the question is how long is that and how will Speedo handle a warranty.
