Tusa BB React BC Back Float Riley Green 2024 Concert Tour Setlist Holler. The BB React Back Float uses a redesigned harness system to improve comfort, stability, and performance in the water. Built for scuba diving, it provides reliable buoyancy control and smooth handling during dives. A new bladder shape design tapers at the shoulders to help maintain posture and balance above and below water. The bladder is made with quick drying TPU double laminated 420D Nyon for durability and comfort. The system integrates several enhancements for easier tank handling and weight management, including the RiteTite tank buckle and strap, the REACT System, and RiteTite Buckle II for quick setup and adjustments. It also features the Advanced Weight Loading System III (A. W. L. S III) and the Ultimate Stabilizing Harness (U. S. H) to support stable buoyancy control in varied conditions.
