Patagonia built the Isthmus Quilted Shirt Jacket with tough, weather-resistant materials for conditions that flutter throughout the day like leaves in the wind. Designed to go from jacket to shirt and back again, the Isthmus has a limber 100% recycled nylon shell with a DWR (durable water repellent) finish to shed moisture and increase durability. The lightweight 60-g (Sleeves: 100-g) THERMOLITE® polyester (92% recycled) insulation wraps you in warmth, feels soft and continues to insulate even if wet. Inside, high-pile fleece rests lightly against the skin and adds even more warmth; smooth polyester taffeta lines the arms to wick moisture and glide over layers. The snap-front design includes a soft, corduroy camp-style collar that protects your neck from wind or sun. Pockets include a left-chest pocket, two front pockets (both secure with snaps) and an internal zipper pocket with headphone compatibility. Elasticized cuffs seal out cold air and gloomy weather. It’s also Fair Trade Certified™ sewn, which means the people who made it earned a premium for their labor. Hip length.
