I received a black one. Wrong kind / color
I have been using this mask for everything covid-19.I just added the filters. Working out! After I got used to this mask. I am utterly amazed by the productivity of this mask. I smoked 🚬 for 30 years plus. I quit smoking some time ago and started working 💪 with Training mask. I am 48 years old. I have to say the tensel strength of my lungs 🫁 have increased and are in excellent condition. I can now hold my breath for 2 minutes and 15 seconds and from what I hear this is almost NAVY SEAL type skills. I have several 3.0 Training masks. I am waiting for the thin purple line skin in support of security officers to show up! I will certainly continue on with Marshon Lynches favorite work out mask!!
Getting comfortable with the breathing technique. Very happy with the idea for endurance treadmill training.
