For all new 2015 Xloop series, this piece is one special item. The frame is thin and extremely light weight due to materials being copper than regular metal. Copper offers more flexibility and it's lighter, so you won't feel the burden on your face after wearing it for a while. The hues on the lenses are carefully designed and each dozen comes in an assortment that makes it easy for you to do businesses. The tear drop shape also gives the regular sporty xloop another realm of sexy and polished city style.
