Built bigger. Built to be worked in. Don't settle for sunglasses made of cheap plastics that could leach into your skin. Know what your sunglasses are made of. Nero is Rockwell's larger performance frame: TR90 Swiss nylon in our Torque-Fit™ build, handcrafted in Northern Italy — a named, disclosed material, not mystery plastic with a logo on it. TR90 flexes under force and springs back to its intended shape without cracking, creasing, or warping, at roughly twice the impact resistance of basic sunglasses and about half the weight of an acetate frame. Nero takes that toughness and gives it more coverage: a bigger lens, a broader fit, a frame that stays where you put it. Nero is a line of builds, not a single build, and we say which is which. Four colourways here — Gray, Blue, Green, and Silver — are floatable builds, made for work and play that ends at the water. Red, Clear, and Yellow are the standard builds, joined by two safety builds — Black and Black/Blue Polarized — carrying Z87+ rated Carl Zeiss Impacto lenses with a Pürcoat™ Ultra Clear finish. Nothing about Nero is vague once you read the lens line below. The Lens Every Nero lens is UV400 — 100% UVA and UVB protection, up to 400 nanometres. Six colourways are polarized — Red, Gray, Blue, Green, Silver, and Black/Blue Polarized — the filter that strips horizontal glare off water, asphalt, and glass and leaves contrast in its place. Blue, Green, and Silver add a mirrored finish. The four floatable colourways carry an oleophobic coating. Clear is the honest low-light option: a true clear lens, unpolarized, for dawn, dusk, and indoor work.
