made my own when i done the sniper course...
few different ways...boiler suit, combats etc....
we just used a 'fishnet' chest rig....and camo trousers.
a variety of materials....hessien (sandbag)...scrim netting...camouflage netting and a bit of spray.
tied it, sewn it, glued it all on...randomly......
rip it up....let it weather...spray it a little....
all i have left from the course is my helmet which i havent touched since....
the more you use it...the more it weathers...the better it looks...
