By limiting air intake, the mask replicates high-altitude conditions and supports increases in lung capacity and endurance.
With the included inserts and silicone membranes, you can easily choose the load level for workouts of varying intensity.
The soft inner silicone feels pleasant and doesn’t press uncomfortably, while the strap keeps the mask stable even during dynamic movement.
The HMS training mask is designed for athletes who want to efficiently increase lung capacity, improve endurance, and strengthen the respiratory muscles. By restricting air intake, the mask mimics breathing at elevations of approximately 900–5400 m a.s.l., making the body work harder and more efficiently.
Thanks to various combinations of inserts and membranes, you can easily set the resistance level to match your current performance. The silicone interior is pleasant to the touch and doesn’t cause pressure points, while the durable strap keeps the mask stable in place even during dynamic training.
