Lightweight, comfortable and warm, the Light Gust Jacket is an insulated, full-zip staple for mixed weather and traveling light. The shell and lining fabric is built from stretchy 100% polyester (70% recycled) taffeta that's treated with a durable water repellent (DWR) finish made without intentionally added PFAS to shed moisture, and insulated with 60-g Thermogreen® 100% recycled polyester.
