A handmade bespoke coat crafted from the premiere waterproof fabric. Loro Piana's Storm System consists of a water-repellant treatment that creates a protective barrier around the wool fabric's fibers. The outer-layer protection causes water droplets to slide off the surface and protect the wool fabric from stains, dirt, and dust - while the underside's polyamide composition makes the fabric breathable and windproof. These combined effects keep you dry, warm, and totally comfortable.
