A closer look
36 resistance level combinations: Adjustable flux valve system on the Black Out variant lets you fine-tune training intensity through multi-level airflow restriction.
Two colorways -- Black Out and Turn Flow: Black Out runs the classic flux-valve cap system. Turn Flow swaps in dial-style Turn Flow resistance valves for a streamlined adjustment workflow.
Inspiratory and expiratory resistance: Loads both directions of the breathing cycle to condition the diaphragm and respiratory muscles for stronger lung capacity over time.
Clinically studied: Validated by a study published in the International Journal of Environmental Research and Public Health on HIIT training with elevation masks.
Ergonomic design + adjustable strap: Secure, snug fit for running, weightlifting, cycling, and HIIT workouts -- no slipping during intense sessions.
Three sizes by body weight: S 100-149 lb, M 150-249 lb, L 250+ lb.
