To use this vest, simply zip up the chunky nylon zip and fasten the snap placket closure. The hand - warmer welt pockets are great for keeping your hands warm when you're out in the cold. You can adjust the waist tabs to make the vest fit you just right. When it comes to cleaning, follow the care instructions on the label. It's best to wash it in cold water to preserve the water - repellent and abrasion - resistant properties of the Microwax canvas. Avoid using harsh chemicals as they may damage the fabric. Store the vest in a cool, dry place when not in use to keep it in good condition.
