Acetate

A high-quality plastic made from natural fibres. It allows for rich colours and patterns (e.g. tortoiseshell) and has a premium feel. It's the favourite material of fashion houses.

Metal

Slim, understated and timeless. Ideal for classic shapes such as the Aviator. Modern alloys offer both lightness and durability.

TR90

A “memory” thermoplastic — extremely light, flexible and almost unbreakable. That's why it dominates in sports and children's eyewear.

Titanium

The premium material: featherlight, exceptionally durable and hypoallergenic — ideal for sensitive skin and for anyone who wants to forget they're wearing glasses at all.
