From Smith
"If you like the classic looks of our Lowdown 2 sunglasses and your face is on the large side, then this XL version is for you. The bio-based frames have soft rubber nose pads, so they don't slide down when you break a sweat. They come with your choice of crystal-clear Carbonic lenses or Smith's color-boosting ChromaPop™".
In 1965 Dr. Bob Smith (an original ski bum) developed the first sealed thermal lens and breathable vent foam. He hand built goggles in his garage and sells them out of his van on weekend ski trips in Utah and Colorado.
Smith belongs to a community of seekers, anglers, and everyone in-between. Their choice of both GLASS and POLYCARBONATE lenses makes sure they're suited to all outdoor lifestyles.
Smith officially Incorporated as Smith Sport Optics, Inc. dba Smith Opticsin 1989. Plenty of retro in this brand.
