The keyhole classic, built the Rockwell way. Monaco is the frame that proves a classic silhouette and a modern material are not enemies. The shape is timeless — a keyhole bridge, a shallow-bumped top bar, lines that have suited faces for generations. The build is not: a TR90 Swiss nylon frame with a rubberized exterior, handcrafted in Northern Italy, featherweight on the face and finished with a grip-friendly texture that stays put. Know what your sunglasses are made of. Monaco's material is named and disclosed — TR90 Swiss nylon, the memory frame that flexes under force and springs back to its shape instead of cracking, creasing, or warping, at about half the weight of an acetate frame. Fifteen colourways run from black-on-black restraint to kelly green and a red/white/blue patriot edition; every one carries the same black lens and the same Italian handcrafting. The Lens Every Monaco lens is a black lens with UV400 protection — 100% UVA and UVB, up to 400 nanometres. These fifteen colourways are the classic line, stated plainly: where a Monaco build is polarized, Rockwell sells it under its own listing and names it there. Here, what you see is exactly what you get — Italian-made TR90, a black lens, and complete UV protection.
