But using a sports mask can double the effectiveness of your training by restricting your breathing and simulating the rarefied air of a high altitude environment to enhance the efficiency of your workout. BENEFIT FOR TRAININGThe best feature of wearing a sports mask for exercise is that it will reduce the amount of air inhalation. Reducing air inhalation (which also means reducing oxygen inhalation) enables the lungs to increase activity in order to adapt to the hypoxic environment, improves blood circulation, and enhances the utilization of oxygen by the body's muscles, which in turn promotes the effectiveness of the workout. MULTI-LEVELS CAN BE ADJUSTEDThis mask has three adjustable valves. The two small valves on the left and right side of the front cover have 4 levels each, and the one large valve at the bottom of the front cover has 6 levels, a total of 48 different combinations can be made! With up to dozens of combinations for you to adjust, you can change the level you need at any time while exercising. DURABLE AND COMFORTABLEThe main body is made of silicone and the front cover is made of high quality plastic for durability. The mask straps are breathable and elastic, allowing for a comfortable fit on the face. By the way, the front cover can be mounted and dismounted repeatedly, making it easy for the user to remove the mask strap for cleaning at any time. WIDE COMPATIBILITYCan be used in a variety of sports: jogging, hiking, weight lifting, cycling and other cardio exercises. Choosing the workout that best suits your needs, combined with the use of an exercise mask, can help you achieve your fitness goals sooner rather than later.
