The Article One x Ciele Athletics GTGlass Italian eyewear feature CR-39 polarized lenses that block out 100% of UVA/UVB rays. In fact, the lenses also prevent road glare, while the backside has a coating that reduces reflections. Made from TR90 polymer plastic, this Italian eyewear is lightweight and durable, helping it remain comfortable during everyday wear. In fact, the hypoallergenic material holds its shape—even in high temperatures. Also, the silicone nose pads grip and hold in place. The spring hinges provide some give and bounce in case of rough wear, but they won’t become misshapen with regular use. Your purchase also includes an impact-resistant molded carry case to protect your eyewear when you’re not wearing them. This case is wrapped in recycled PET fabric with a useful clip for storage.
