Sidemount and stage divers know the trouble a loose regulator hose can cause. These 1-inch EPDM retainer bands hold hoses snug against stage, deco, and sidemount bottles, and the material stands up to sun, salt, and chlorine season after season. A 2-inch nylon pull tab means you can stretch one over a tank valve even in thick gloves. Rig your bottles clean and keep a spare or two in your save-a-dive kit.
