Zach Galifianakis is one of the friends in the popular 2009 movie The Hangover. Zach's character, and the baby he takes care of, are wearing a pair of demi tortoise nylon Blublocker sunglasses. These glasses are known from TV infomercials and are very inexpensive, available from 16,99 at Amazon! It's the most popular model of Blublocker, and only recently became available in this tortoise color, see the BluBlocker website.
These Blublockers have temples made of memory retention nylon. The temples stretch and contract to fit any size face and the pin hinges are thick and durable. The large lens provides ample protection and the nosepads are molded into the frame itself.
