These glasses are fantastic.  I bought them from a few weeks ago and when I saw them here I wanted to spread the word to those buying them.  They work great for triathletes, and are super light.  So light it takes getting used to because you can't feel them on your face.  Perfect for aero cycling and when sweat drips on them it just runs off the lens without obscuring your view.  Not to mention you may have the sexiest pair of specs at your next race.
