That's a tumbling mat used for gymnastics and stuff. I use it for pee wee football when teaching the beginners proper form tackling and allowing them to fall without smacking the ground hard. It has a rough, tacky side that sticks to the ground or floor and wont move easily and a tough, thick, plastic side for the tumbling/falling. Well I use it upside down and the kids clothes just kinda stick to it without really needing to hold on but they will still wipe out though. The plastic side glides across the snow so smooth it's awesome. I'm going to take it down a hill and see how good it goes. Oh, when my sister in law brings her boyfriend up from Florida in the winter time I scare the beejeezees out of him when we go out somewhere and I drive. Once he said that when he was in Atlanta, Ga. they got like a dusting or an inch of snow and shut the whole city down. Don't know the truth to it all but that is what he said.
