Spiravox B4 Anatomical Mouthpiece

Ergonomic replacement for airflow pattern regulation

Fatigue during long workouts often leads to jaw clenching and involuntary biting on breathing accessories. The Spiravox B4 anatomical mouthpiece is shaped to provide balanced support across the molars without straining facial muscles. Its medical-grade silicone design ensures stable retention with minimal effort. It attaches securely to standard tubes and regulators through a reinforced engineering ABS polymer neck, keeping every inhalation natural and comfortable during running form drills.

We often see small gum lesions caused by hard, poorly fitting sports mouthpieces. The Spiravox B4 design distributes force across the molars and keeps the lips relaxed.
