I bought the 2 piece Ghillie-Suit.com version. I pack the pants in and put them on when I get to my hunt location. I tried wearing them once, not only do they "snag" a lot, but I heard of becoming one with the woods, but by the time I got out, even hiked up high, the woods had become one with ME!
I'm still trying to comb out needles, twigs, leaves and other debris!
But sitting flat on the ground, up against a tree, with hat, gloves and top/bottom on, turkeys walked right by me in the fall (3 days before opener) and have had several come in for spring.
Small birds are a slight problem though wishing to nestle in my gear!
