It cuts the wind completely, and the DWR coating handles light rain without soaking through. The elastic hem and cuffs give it a snug fit without feeling tight, and I like that the zippers and branding give it a sleek, modern look.”From seaside strolls to chilly hikes on exposed ridgelines, the Koster Windbreaker Jacket is our go-to for lightweight weather protection.
