Should have bought sooner - 221B Tactical Maxx-Dri Vest 4.0 Body Armor Ventilation

Wearing an outer vest I love wearing this under. I stay cooler and my vest stays dry. If you work in an area where its hot and humid its worth giving this thing a try. The 4.0 works great under the outer carrier as well with the length. The 3.0 would probably be fine under an inner vest though.
