For all extreme athletes who want to take their training to the next level with the Phantom training mask. 
The patented PRS ( Phantom Regulation System) is the core of the Phantom training mask and offers you the most advanced breathing resistance control on the market. This allows you to adjust the resistance at any time during your workout without removing the mask or interrupting your workout.
The PRS X-Treme is now the evolution stage for all those who the standard PRS is not strong enough. It intensifies all 4 resistance levels by an average of 40%, giving you the hardest workout you've ever had. The PRS X-Treme is very easy to change. Click your standard PRS out of your Phantom training mask and put in the new PRS X-Treme and you're ready for your workout. And so you can show the world how hard you train, the PRS X-Treme comes in an exclusive red colorway with a unique carbon cover.
