• "7 Layers of Protection" are created by combining ultra strong woven fiber material combined with composites that harden with contact with air. Evoshield Chest Shirt uses these ultra-thin and ultra-lightweight shields that custom form to the athlete then permanently harden to disperse energy from impact. Our wicking, 4-way stretch shirt holds shields in pockets in the correct position, and provides pocket openings that allow removal of shields. Shields can be removed for hand washing or at times when not needed for protection. The A100 shirt has a chest shield and two back rib shields. The back protection was recommended and implemented as a part of the shirt due to input by experts who analyze dangerous impacts on players. The back( under the scapulas) is an area of chest impact vulnerability not addressed by other products currently sold claiming chest protection.

According to current research, NO protective device or chest protector can claim protection against commotio cordis(sudden heart failure death due to chest impact that in most instances,results in fatal injury). Over 700 deaths have been recorded attributed to sports participation, including 30 deaths to catchers who were wearing some form of chest protector at the time. In these recorded cases, the autopsies revealed no pre-existing heart defects of any kind. Of further concern is the fact that response to resuscitation efforts is poor. CPR is of little use when heart stoppage occurs. The injury produced by blunt external trauma is a functional rather than a structural injury. The trauma of impact produces a variety of cardiac electrical abnormalities, including repeatable arrhythmias and traumatic apnea. The danger to young athletic participants is particularly high since almost all the energy of impact is ransferred to the chest because ball rebound after impact is minimal.
Two areas of possible prevention have been researched extensively inthe past: 1. Using balls with softer cores. 2. Various means of padded chest protection. Softer balls seems to make little difference in the effect. However, the limited protective padding worn by hockey players seems to offer some protection. Although hockey players routinely receive chest blows, and the hockey puck travels at high speed and is harder than a baseball, relatively few players have suffered commotio cordis. The material has performed in independent university tests as well as anything commercially available in energy absorption capability, and has been worn in competition for more than several years by his own son and other players competing in youth sports around the country. The players themselves report that their performance is not hindered in any way. They contend that performance is actually improved due to the mental confidence they experience from wearing the "Body Armor." The fear of painful injury is reduced and hence the boys perform with fundamentally sound baseball mechanics and with more confidence.
