Really excellent quality! It has a pleasantly strong, tough plastic and Vaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaen: 2-3 others I've bought. It can stand on the bed by itself when buckled up! The fit is very good for my fairly muscular 5'9"44R body - and it has 2-3 extra buckle holes for both pairs of straps. I think a man under 40 inches might have too many loose straps on his chest, but I do can't say for sure.
