XXL Colonel eyeglasses speak to the modern man looking for strong, refined lines and a classic silhouette. The rectangular rims are crafted from Monel, a corrosion-resistant copper and nickel alloy that retains its stability and shape. The slim wire-core temples are comfortable, made from lightweight, lustrous acetate–a hypoallergenic plant-based plastic. Flexible spring hinges offer a secure fit. XXL has built a reputation for exceptional comfort and fit, and these Colonel glasses are a fine example of their continued craftsmanship.
