I've played and I wear jeans, sweatshirt and camo. I also wear knee and elbow pads under the camo. It'll save your joints when crouching and crawling. Since this is a first, you are def going to be spraying at everything, just take it ez and move a lot. Dont stay in one place too long. Have lots of fun. You'll go home tired and in the AM you may be sore!
