Works fine to exercise my deep breathing needed in higher elevations. The fit is great and it doesn’t slip at all once I start sweating.

I’ve never used such a mask and I’m impressed! With I had got it sooner. Phenomenal quality and it’s very comfortable to wear! Decided to run to try it out and I had no issue keeping my breathing controlled.
