The Monza men's round acetate sunglasses combine a thin, rounded deep black frame with orange lenses for a look with a touch of mystery. Made from bio-based acetate and fitted with CR39 lenses with UV400 protection, they bring quiet character to even the most ordinary day, from the commute to a weekend away.

Key Features

• Thin rounded frame with a light, refined outline
• Frame made from bio-based acetate, produced with plant-based materials for a smooth, substantial finish
• CR39 optical lenses, valued for their clarity and light weight
• UV400 protection to filter UVA and UVB rays on bright days
• Supplied with a soft felt cover made from recycled plastic bottles, in recycled packaging
• Frame measurements: 54 mm lens width, 17 mm bridge, 145 mm temple length

Fabric & Care

The frame is bio-based acetate made with plant-based materials, paired with CR39 lenses offering UV400 protection. We recommend cleaning the lenses with lukewarm water and a microfibre cloth, and avoiding household cleaners or paper towels, which can mark the surface. Store the glasses in their felt cover when not in use, and keep them away from strong heat such as a car dashboard, as acetate can lose its shape at high temperatures.

Fit & Sizing

One size. With a 54 mm lens width, 17 mm bridge and 145 mm temples, this is a balanced frame that sits comfortably on most adult faces. If you usually wear wider frames, compare these measurements with a pair you already own before ordering.

How to Wear It

The orange lenses add warmth to darker outfits. Wear them with a black T-shirt, an olive overshirt and black jeans, or with a white shirt and stone trousers (pants) in summer. They also pair well with a navy knit polo and tan suede shoes.

Compare your measurements with the size guide beside the size options.
