HOW DOES IT WORK? Our Summit Mask technology uses two adjustable levers that easily adjust while training without having to remove the mask. Unlike other masks, you not only get restricted inhaling but restricted exhaling as well with our dual flux valve design allowing for 3 breathing variations. A simple quick flip of the airflow valves, and you can force your lungs to breath in AND out. Level one simulates lower altitudes while level four simulates the highest altitude. This mask will push your breathing limits, strengthening your lung capacity and stamina. It will greatly benefit athletes, and people in physically demanding careers such as: firefighters, military, lifeguards, and law enforcement.

WHAT ARE THE BENEFITS? Prime Athletics Summit Mask simulates the effects of training at high elevation by regulating airflow during inhalation and exhalation taking you to elevations of 5,000 to 21,000 feet above sea level. Maximize your training by getting results in a shorter amount of time. This training device pushes the limits of serious athletes by increasing lung capacity, strengthening the diaphragm and boosting stamina. Take your training to the next level!
