Grey Polarized Sunglasses | Piuma by 20 Grammi

Some things don’t need to shout to be noticed. The Piuma Grey Lightweight Polarized Sunglasses by 20 Grammi offer a quiet blend of clarity, performance, and modern utility. Handcrafted in Italy from TR90—a high-performance material known for being ultra-light and nearly unbreakable—these frames weigh under 20 grams, making them feel nearly invisible on the face. The polarized poly-HD lenses cut glare and improve contrast, offering 100% UV protection (Category 3) even in strong sun.

Whether you’re weaving through city streets, heading out of town, or walking Geneva’s lakefront, this is eyewear that adapts to your rhythm—sharp, subtle, and made to last.
