Patagonia M's Lined Isthmus Vest

Weather-Resistant Vest with Warm Fleece-Lined Comfort

The Patagonia M's Lined Isthmus Vest is a versatile layer built for core warmth, wind resistance, and everyday protection in cool weather. With a durable NetPlus® recycled nylon shell and soft recycled microfleece lining, this vest delivers reliable comfort for town, trail, camp, travel, and daily layering.

NetPlus® Recycled Nylon Shell

The shell is made from 100% NetPlus® postconsumer recycled nylon faille, sourced from recycled fishing nets to help reduce ocean plastic pollution. A durable water repellent finish made without intentionally added PFAS helps shed light moisture and adds weather-resistant performance for changing conditions.

Soft Microfleece Lining and Secure Storage

Inside, 100% recycled polyester microdenier fleece provides toasty core warmth with a double-sided, anti-pilling finish for long-lasting comfort. A full-zip closure, microfleece-lined stand-up collar, and protective wind flap help block chill, while zippered handwarmer pockets and an interior chest pocket keep essentials secure.
