How to use: You can wear this vest as a mid - layer under a heavier jacket in cold, dry weather to keep your core warm. Or, wear it on its own during rest breaks or at camp. When you're not using it, just stash it in the included stuff sack and put it in your pack. Attention: Avoid exposing the vest to sharp objects to prevent tears. Also, try to keep it dry as much as possible, especially in areas with the Coreloft synthetic. Maintenance: It's best to clean the vest according to the care instructions on the label. Usually, a gentle machine wash in cold water and air - drying will work well. This will help keep the down fluffy and the outer fabric in good condition.
