Using this DC men's puffer vest is easy. Just zip it up at the front and you're good to go. It's perfect for spring and summer days when you need a bit of extra warmth. When it comes to pockets, you can use the welt pockets with zip closures to keep your small items safe, like keys or a phone. For maintenance, you can machine wash it on a gentle cycle with cold water. Use a mild detergent and avoid using bleach. Hang it to dry instead of putting it in the dryer to keep its shape. Also, make sure to close all the zippers before washing to prevent damage. This way, your vest will stay in great condition for a long time.
