A friend gave me a leafy suit, probably 10+ years ago. It has some unknown pattern on it, a mixture of several shades of brown, green and gray. It was very noisy, so I washed it in plain water and dried it several times until it was very quiet. It has a mesh base, it's very light and air flows through it very easily.
I have no idea who made it and have never seen another one just like it.
I've worn the jacket and/or pants for part of the spring and turkey seasons for all these years, in various parts of the country with different terrain and brush, trees, etc. When I've done my part, I've not been "busted" by a turkey or any other animal.
I can't tell you that it's any better than any other type of camo but I can tell you that I feel very confident in it and that makes some difference to me and how I hunt. I think that's one of the most important parts of any camo, how we feel about it.
I have a friend who hunts in an old set of coveralls that I spray painted with some stencils because he wanted camo but didn't want to spend the money to buy some. He's hunted in those things for years, and shot 2 or 3 turkeys a year. He swears by those coveralls, feels confident in them and they help him get his birds every year.
