To use this jacket, simply put it on like any other jacket. The helmet-compatible hood can be adjusted to fit your helmet when you're skiing or snowboarding. The powder skirt helps keep snow out, so make sure it's properly attached around your waist. Use the ventilation system when you start to feel too warm. When it comes to maintenance, follow the care instructions on the label. Usually, you can machine wash it on a gentle cycle with mild detergent. Avoid using bleach or fabric softeners. Hang it to dry to keep its shape. And always check for any damages or loose seams after each use and repair them if needed.
