Using this vest is easy. Just put it on over your regular workout clothes. You can use the two zippered side pockets to store small items like keys or your phone. When you're done with your workout, it's best to machine - wash it on a gentle cycle with cold water. Avoid using bleach as it may damage the reflective print and the fabric. Hang it to dry instead of putting it in the dryer, as high heat can shrink the vest or affect its insulation properties. Keep it in a cool, dry place when not in use. And remember, this vest is designed for cold weather workouts, so don't wear it in hot conditions as it's made to keep you warm.
