“Take back your breath! ``Levuna'' is a mask-type training gear for nasal breathing. Breathing valves installed in the nasal and mouth chambers of the inner mask force breathing through the nose. Nasal inspiration and valves increase breathing resistance. Depending on the direction of valve insertion, you can select the breathing pattern that suits your exercise, such as yoga or Pilates. Breathing resistance can be adjusted in 3 stages by replacing the valve (optional). The outer mask material is made of wetsuit fabric, which is highly wearable and moisture absorbent. Olefin-based elastomer is used for the inner mask material, giving consideration to fit and hygiene. The two-piece construction, inner and outer, makes it easy to clean and maintain.
