Women’s bodies have a defined waistline where a waistband must fasten to secure the BC. However, with shorter torso lengths and a lower center of buoyancy, traditional buoyancy systems must sit higher, around the narrowest part of the waist, compromising comfort and balance. The Zena’s innovative twin waist and hip band system allows weights and buoyancy to be positioned below the waist, aligning with the body’s center of buoyancy for improved stability and comfort while diving.
