What Our Gearhead(R) Experts Are Saying: "I've been wearing the Light Gust Vest on chilly morning hikes and shoulder-season travel days. It's super lightweight, surprisingly warm, and layers really well without adding bulk-an ideal piece to keep in rotation all year." We keep the Patagonia Light Gust Vest close when the forecast can't decide between brisk and balmy. With its full-zip design, low-bulk insulation, and lightweight recycled materials, it's a versatile layer for trailheads, airport gates, and everywhere in between. The shell and lining are made from stretchy, 70% recycled polyester taffeta with a water-shedding DWR finish that's free from intentionally added PFAS. Inside, 60g Thermogreen(R) insulation traps warmth while maintaining a trim, layer-friendly fit. With thoughtful features like a vertical-zip chest pocket, dual handwarmer pockets, and Fair Trade Certified(TM) construction, this vest balances performance, packability, and responsible design.
