Elevation Training Mask 2.0

“Elevation” Training Mask. Size small. It’s technically has nothing to do with elevation training. It provides resistance against breathing while training. Can it be beneficial? Sure. Does it up your training? Not entirely, but you look pretty bad ass. Has it helped me? A bit yes. Should I have bought two? My wife says no. So I’m selling this second one new, sealed and in the box for cheaper than what I paid.
