The Viking C-2019 mask is designed to strengthen the muscles of the lungs and diaphragm, increasing their elasticity. It features special valves that create "resistance" during breathing, resulting in the lungs working harder, thereby enhancing your endurance.

You can wear it during any workout, including exercises such as crossfit, martial arts, cycling, and running. It is suitable for all fitness levels, as the valves offer different levels of airflow intake.

This mask is an essential accessory for your training sessions!
