Persol is known for its Italian-made acetate frames. For the PO5003ST aviators, the brand breaks its tradition and borrows from another heritage. The classic silhouette is forged in Japan by local masters using titanium to deliver light yet durable sunglasses. Available in two variations, the matte black option features grey gradient crystal lenses while the brushed navy comes with polarized light blue lenses. Both are finished with the brand's signature arrows at the temple.
