GAST is an independent brand based in Milan, born to blend diverse cultural influences through high-quality artisanal eyewear. Each frame is handmade in Italian Mazzucchelli acetate and takes shape through over 50 production stages, ensuring precision, durability, and attention to detail. Some models use M49 bio-plastic, an eco-friendly, biodegradable, and recyclable material, consistent with a more sustainable vision of production. The result is a contemporary design that makes luxury more accessible, without compromising on quality, ethics, and environmental awareness.
