I don't wear them. I would wear them if they made it easier to wear them when you are actually climbing up or down which is when most people fall. I don't see any point in wearing it when I'm just sitting in my climber. However, I do scare myself sometimes when I don't realize how high I have climbed before dark and then I look down and realize I'm 50 ft up a thin pine with no safety harness. I guess I'm young and foolish...
