These broke in half at the nose after falling from my head to the GRASS after less than one month of owning them.  I love the fit and had owned and used a similar style from Adidas - they were great and lasted over 2 years and must have been higher quality.  I used them almost every day for biking and/or golf.  Customer service was very short when I explained what happened to then new pair.  I would not purchase again from them and will look at other alternatives.
