Bests & Worsts Reviews from Amazon

I teach fitness classes at the gym and I've tried at least 30 different masks. This is the best one. Is it perfect, no. But, it's the only mask I can keep on during a whole one hour class without suffocating. The other masks get completely soaked inside/outside, which takes away from the effectiveness and I have to do mask changes at least 3-5x's during a cardio type class. Yes, this one still gets hot and sweaty inside but the outside remains dry and the mask keeps its shape away from my face so I can breath. It is the most soft mask and feels like a pillow. The top nose piece actually is loose and will slip when I start doing jumps and higher intensity workouts, however, I accidentally put it on upside down once and it's actually better. The chin piece is really secure and fits my nose perfectly. It's expensive but worth it to me, I ended up buying several more so I didn't have to handwash the one after each class to have it ready for the next day's class.
