Whatever you get, make sure that it has a DETACHED hood, because an attached hood doesn't turn with your head, and many times when you do turn your head you are looking into hood, instead of what you are trying to see.
You also want to get someone to help you trim it so it won't interfere with your bow. I like to use an old knee sock with the foot part cut out of it on my bow arm to keep everything out of the way. The suit I have....the Rancho Safari Shaggie Longcoat....has built in adjustable straps on both arms for this purpose.

Color is unimportant unless you are using it to hunt turkeys, waterfowl or human beings.....[:D]
The main drawback to wearing one is when the squirrels try to run over you, and the birds start to land on you!
