I've got on quite a few layers here: tshirt, hoodie sweatshirt, and then massive camoflauge jacket.
Strapped around my waist are paintball refills, and you can see the tip of my gun there too.
We played nearly 10 separate games with a variety of rules on a variety of different fields. I ran around a bit, but mostly squatted and shot over the edges of bunkers. I had some good kills, though they were outnumbered by the number of times I was shot myself.
It was a pretty fun day out. I've got some welts–mostly waist down, the only pants I had on were the jeans, and they didn't offer much protection. But still fun.
