What Our Gearhead® Experts Are Saying:"This jacket is like a throwback shell with a smart twist—it's warm, weather-resistant, and way more sustainable than your average outer layer. I’ve worn it in light rain and wind without needing to layer up much underneath. It’s a solid piece for transitional seasons."Built for breezy days, spontaneous road trips, and city chill, the Isthmus Jacket blends old-school style with Patagonia’s eco-driven performance. It’s crafted with a rugged NetPlus® shell made from recycled fishing nets, designed to reduce ocean plastic pollution while standing up to wind and light precipitation thanks to its DWR coating. Lined with soft, quilted polyester and packed with lightweight Thermogreen® insulation, this jacket traps heat where you need it—without ever feeling bulky. A full-coverage hood, interior storm flap, and secure pockets make it trail-worthy and commute-ready. Whether we're chasing surf or just a slice of blue sky, the Isthmus is our trusted layer for casual adventures and cooler temps.
