How to use: You can wear this jacket on its own when the weather is cool but not extremely cold, like during forest hikes or climbing. For colder and wetter conditions, layer it under a waterproof outer jacket. Notice: Avoid sharp objects that may tear the jacket. When wearing it for high - intensity activities, make sure the fitted style doesn't restrict your movement too much. Maintenance: Follow the washing instructions on the label. Generally, use a mild detergent and avoid using fabric softeners as they may affect the performance of the insulation and DWR finish. Let it air dry instead of using a dryer to keep its quality.
