I made my own this past summer. I was doing my clinical rotations in a hospital, and i was required to wear a long white labcoat that hung to my knees.
After I was done with it, I died it dark green, sewed camo netting to it, then tied pieces of jute twine to it. For color, I hit it with camo spray paint. I like that I can change the color like that to correspond with the terrain an the seasons.
I've worn it several times so far, and I am pleased with it, however, I know that the labcoat material isn't very durable, so I dont wear it walking or stalking much. Rather I just put it on and sit in my blind or bury myself up in some scrub.
With the price of the labcoat, surplus netting and twine, I think I may have $30 wrapped up in it.
