I have a Rancho Safari Shaggie Suit. It's pretty awesome how much it hides you.

I do recommend getting into some cover. Just standing next to a tree will work, but it's much easier for the deer to pick you out when they get within ten yards.

My friend uses oneandhad a doe come in and browse on the other side of a bush so close he could have poked her with the arrow. He also had a mature buck come within four yards and browse around him. (doe only area)

Birds will land on you, squirrels will practically walk across your feet. It's pretty cool.

I don't put it on until I'm at my spot. The shaggie will grab every briar within two feet of you. (bring brush clippers with you)
Also, practice shooting with it and don't be afraid to trim away anything that might interfere with your string.
