Atomic Live Shield Vest is a ultra-lightweight protector vest. It’s made with multi-density 3-layer foam that’s softer close to the body and stiffer on the outside to gradually absorb shock before it reaches your body. The vest itself is made from highly breathable Air Mesh and Stretch Lycra and has an Active Thermo Fit that adapts to the shape of your back for a neat and close fit. So you won’t feel restricted or look bulky and you won’t overheat even in spring! It also features a waist belt that’s removable and height-adjustable to fit different torso lengths for a great individual fit.
