How to use: Simply put on the jacket when you need wind protection. It's easy to slip on and take off. When not in use, pack it into the included stuff sack and keep it in your pocket. Note: Avoid sharp objects that could tear the fabric. Don't use harsh chemicals when cleaning. Maintenance: Machine wash the jacket on a gentle cycle with mild detergent. Hang it to dry. Avoid high heat as it may damage the fabric and the DWR treatment.
