What are the Levels or Classes of vests?
When vests first came on the market, the government had to stick its nose into the business, being a major customer, that’s OK, but they had to micro-manage everything. Vests were mounted onto blocks of childrens modeling clay and shot. After a while they came up with a catch-phrase. ‘Backface Deformation Signature’ This is a $350,000 taxpayer -funded word meaning ‘Dent’. They then decided that if the ‘dent’ was deeper than 1.73 inches, that was to be counted as a ‘penetration’, or failure. Sooooo, they kept demanding that more and more layers be added to reduce the depth of the dent.
