To use this jacket, simply put it on like any other outerwear. The zippered mesh chest and hand pockets are great for storing small items like keys, phone, or a snack. When you're carrying a backpack, the hand pockets are designed to sit above the waist belt without bunching. In terms of maintenance, you can machine - wash it on a gentle cycle with mild detergent. Avoid using bleach or fabric softeners as they can damage the fabric's water - repellent and windproof properties. Hang it to dry to keep its shape. Be careful not to expose it to sharp objects that could tear the fabric. With proper care, this jacket will serve you well in the mountains for a long time.
