One-size-fits-all design, that's super-easy to get on and off! It's crafted of rugged 1 3/4" nylon flat web, with a quick-secure adjusting buckle system that complements the easy-access tie-in point. CMI recommends the use of a full body harness for all industrial and rescue situations because it evenly distributes your weight in the event of a fall and allows you to safely hang in an upright position. The unique padding behind the thighs/buttocks makes the conquest one of the most comfortable harnesses around.
