I work as an independent contractor in Iraq. Although I live and work without any solar reflection from the surface of glaciers and mountain peaks the desert sun is no less bright and unruly upon my light-sensitive eyes. The Julbo Advance Sunglasses serve their purpose so well Ive just purchased my second pair, as with the living and working conditions here in Iraq it can be difficult to preserve such finer things. These are by far the best pair of non-polarized sunglasses I have worn to date. Moreover, the service at BackCountry.com is competitive at least as mail received by me (just out side of Baghdad) normally takes 2-5 weeks. I received my shades within 8 days from my online purchase. Thanks, R.M.D.
