SATKULL Training Mask 3.0, Gym Workout Mask for Men, Elevation Mask for for Cardio, Running, Endurance and Breathing Performance

I purchased this with low expectations. FYI there are a few models from different sellers which are significantly higher, but are the same exact mask, my guess is they all outsource them from Alibaba or somewhere similar.My goal was to increase my lung capacity and I use these with weight training, Jiu Jitsu drills, MMA/boxing, general cardio such as treadmill/jumprope, etc. They fit well overall with the exception of the velcro closure which is very rough on the skin, I usually put a paper towel under this to help. Functionally they work well, doing the job of restricting breathing in and out. My only gripe is the levers to change the restriction seem a bit flimsy and one of them is already not snapping into place and I anticipate it may break soon.

Cuando compre la mascarilla, la compre x tema de la pandemia y porque las mascarilla se me pegan al rostro y no me dejan respirar. Al ver videos observe que estas mascarillas son para generar Hipoxia, lo cual según estudios no mejora el rendimiento y permite ingresar el aire sin protección. Logré solucionarlo colocándole un filtro. Al usarlo en crossfit donde es una clase muy exigente, por primera vez ha sido toda una experiencia. Esta mascarilla obliga a poder respirar como debe ser de lo contrario se siente una falta de oxígeno. Es la primera vez que respiro en forma correcta gracias a la mascarilla y a pesar que si genera sudor, creo que el beneficio lo vale. Lo recomiendo para aquellas personas que desean mejorar su forma de respirar y aumentar su capacidad de respiración.

Looks cool. Comfortable. Not filtered but I addedy own carbon filter easily enough for COVID. Muffles speech so it's hard to hear the wearer when they speak.

Pretty nice, the one thing I’d recommend is the strap that goes behind your head to latch with the Velcro, the Velcro to latch can be bigger for people with smaller necks. While running it bounces around because I can’t get the snug fit as desired. If that happens, it’s a phenomenal mask. But overall a wonderful mask.

This thing is horrible not as seen in pictures, sides have holes in them, so it makes your checks come out through sides & just ugly and bulky not at all what it looks like. Waist of money.

The front cover keeps falling off.

Looks great but its too small to fit on the face. Chin sticks out in the bottom. Too much condensation build up from breathing. Very uncomfortable for long periods. Hard to breathe wearing it. Youll have to take it off after a few minutes.

Good price alsoEverything is good in this productThe price is reasonable for the quality of the produ t
