The greatest difficulty in properly sizing a woman's Buoyancy System is not finding a smaller size, or allowing for the bust, but lies in the fact that women's bodies have a defined waist where a waistband must fasten in order to secure the BC. At the same time, women tend to have both a shorter torso length and a lower center of buoyancy compared to men. So conventional buoyancy systems,which would ideally be worn lower for best balance and comfort, must be worn higher, around the narrowest part of the waist, in order to be secure. The Zena's twin waist and hip band system provides a way for women to securely position the weights and buoyancy below waist level, around the body's center of buoyancy. The Zena closes in the front with a heavy-duty zipper for a snug and secure, yet non-restrictive fit. A ripcord release weight system is standard.
