Abstract

A layered protective garment endowed with bulletproof and knife-proof properties comprising a long shorts style garment that covers from waist to mid-calf level comprising at least three layers. One layer being of high tensile strength such as Twaron; the second being an air gap layer; the third being a layer of hexagonal Kevlar pieces.

Background to the Invention Gunshots and bullets are menace in present period, both in war and in peace times. The injuries can be from both blunt penetration and. kinetic energy impacted. on tissue. Kevlar is a well—known material with high tensile strength to stop bullets and reduce impact energy. '9 .9 W9 9,90 \ Curfent bulletproof garments only providewfiie complete layenfifif Kevlar meaning the garment is bulky and uncomfortable. The current invention is a garment produced using Kevlar but with hexagonal shapes of differing sizes closely applied together allow bending and twisting without loss of cohesion and thus can be used to allow a dungaree type fitted long shorts that is easy to wear and still retainability to protect from penetrating bullets.
