I've seen that stuff before in action, it really is pretty cool, and definitely one of those helpful things to keep in your trail bag incase you need it.
I believe the guys who made this were on Shark Tank.
We used some of that to make a ski tower on a boat. Small one on the back. .didn't hold up too long lol. Snapped when pulling 3 adults at once lol. Probably would have held up if the poles were better positioned. Leave it to a guy who wouldn't listen to me and found out the hard way lol
