For all extreme Athletes who want to take their Phantom Training Mask experience even further! 
The patented PRS (Phantom Regulation System) is the core of the Phantom Training Mask and offers you the most advanced resistance regulation on the market. With it, you are able to switch your resistance levels during your workout, without taking off the mask, and fully concentrating on your training.

With the PRS X-Treme we are now taking it to the next level. It is intensifying the resistance by an additional 40%, bringing you the hardest workout you've ever experienced. The PRS X-Treme is extremely easy to change. Simply click out your standard PRS, insert the new PRS X-Treme and you are ready to go.

And to show the world how extreme you are, we deliver the PRS X-treme in an exclusive red color with an awesome looking carbon style Cover.
