TRAININGMASK Training Mask 2.0 | Gym Workout Mask – for Cardio Stamina, Running, Endurance and Breathing Performance [Official Training Mask Used by The Pros}

I first did not like it but I purchased N95 filter now it is my favorite mask

This this does exactly what it says it does! My lungs have never felt stronger and have only been using it for 2 weeks! Only downside is that as you sweat the mask has a tendency to slide down your face, which does get annoying sometimes. But overall I would definitely recommend getting this product!

Really helps you to control your breathing.. im in the academy and i highly recommend this to help with the scba mask

My endurance for the race prep I’ve been doing is marvelous! Just switching from mask to no mask and feeling and seeing the difference in my times are great! This is an incredible product I even bought one for my wife to train in!

We ordered the small size for my 12 years old kid (kick boxing classes). The quality is really good and fits perfectly. He really liked it.
