To use this men's high altitude snow jacket, simply put it on like you would any other jacket. The powder skirt can be adjusted to fit around your waist to keep snow out. When wearing a helmet, the helmet-compatible hood can be adjusted for a proper fit. Use the underarm vents when you start to feel too hot to let out excess heat and moisture. As for maintenance, follow the care instructions on the label. Generally, it's best to machine wash it on a gentle cycle with mild detergent. Hang it to dry instead of using a dryer to protect the materials. Also, avoid sharp objects that could damage the jacket's surface.
