The phantom training mask is a training device that helps you to train your breathing muscles. It sets your focus on your breathing by limiting your air supply during training. This makes it harder to get your lungs filled with air and strengthens your breathing muscles which increases your performance when training or competing without the mask. It allows you to easily switch resistance levels during training without taking your mask off. It provides four levels of resistance, from beginner to extreme, to constantly push your limits.

Features:

• Train your breathing muscles and increase your performance in any sport
• Change resistance levels easily during training without taking your mask off
• Ultra lightweight, anatomically designed sleeve that will not slip during training
• Use of only the best, hygienic and anti allergic materials, medical silicone and resistant nylon.
