Risk never clocks out. Neither do Gargoyles Rampart sunglasses, offering serious protection for the kind of performance you would expect from a bulkier, heavier frame. Since Gargoyles is always about protection without sacrificing optical clarity, Rampart exceeds ANSI Z87-2 standards, which include high velocity impact and high mass impact protection. And you also have the option of adding prescription lenses. Additionally, rubber is co-injected into the frame to fuse them together. So the inside browbar is actually part of the frame. And while the vented, ribbed nosepad stays put, the air flowing around them will not. The temples are secured with G-Loc hinges. So they are open or closed, no middle ground. In short, Rampart has a look that appears casual while solidly exceeding our extraordinary standards for serious protection.
