They wear camo clothing to hunt.
In this case Roman took an old gray terry cloth bath robe and made an excellent ghillie out of it. When I was there, he put on his ghillie around the corner of the shop, then told my kids to find him. There was a corn field next to the shop and they had cut the corn and stacked them in shocks, he was hiding next to a corn shock, if he hadn't moved we wouldn't have found him. He did an excellent job on the ghillie. He wasn't wearing it when he killed the buck though. He was about 20 foot up in his tree stand.
