"Good Interchangable Glasses" - Review of Smith Threshold Sunglasses - Interchangeable

I've liked my pair of Thresholds for biking best. The light weight frame allows me to ride longer rides and never even feel them on my face. The option of a clear lense is also huge for me and I like to ride DH with a clear lense for use in and out of the trees. The new Interlocks look sweet, but if you want light weight, go with the Thresholds. Get a polorized lense and a clear lense and you'll be set.
