This is an assist belt that can be used for snowboarding and skiing. I used it for snowboarding with my siblings for about 4 seasons. This harness can limit speed, and you can somewhat control the edges by pulling the assist ropes on the stomach and back. It's good for going straight. The way I used it, my parents were constantly using the "falling leaf" braking technique, so my legs were killing me. (lol) If you have any questions, I can write about how I used it, what it was like, etc., so please ask. The photos on the 3rd and 4th pages are from the internet, so there is no box. Please understand.
