Med-Eng Systems

Please note my lack of knowledge in the tactical arena. This was picked up at a thrift store and is quite unique and rare. The front protector piece is the only marking I can find anywhere indicating Chem-Eng Systems as the manufacturer. Nothing inside the vest or anywhere else indicates otherwise. After trying it on, I’m comfortable giving it an XL sizing. Please ask any questions and I can get better pictures if need be. Please see photos for detail. Thanks! Bin E8
