This is a fantastic all-in-one protective mesh shirt/jacket. I love this on its own or under a jacket/shirt/sweatshirt. Please refer to the Knox website for a full description. Removable shoulder, elbow, and back armor is included. It is clean, no rips, stains or scratches. All zippers work, both thumb loops intact. I am a size 10/medium/36D and this is extremely snug. I recommend this for size 6-8/small or smaller.
