I've never felt the need to wear one. In fact i usually never use tree spikes for climbing either I always find a natural set up.But frankly set your stand up properly. Dont get lazy and fall asleep and if your falling out of a tree because you have bad balance you probably shouldnt be in one. Further more siding contractors like myself across the globe rely on a plank and ladder jacks to be suficiant enough to hold them 30 ft in the air without harnesses. Since when did Hunting become a pansies sport....
