Review on 🏋️ NS NESIAN SPORTS Hex (Hypoxic Exercise) Mask - Elevate Performance with Altitude Breathing Simulation - Dark Gray by Paul Lee

Works the same as the $60-$70 training mask. I brought three workout masks recommended for 2020 and after trying my low to high resistance breathing techniques I'm impressed, now it's time to get back to the gym to tackle light weights. Just got it today during co-vid 19. It can sting your lips when you turn the resistance knob and if you want a breathing resistance at a lower price, get this. I don't know how durable it will be as I know my test training mask will last me 6-8 months can keep running for a long time. My head is medium sized and with this mask it is roomy. You know, when you start to feel your mouth moving, you know you have a REAL WORKOUT MASK AND NEED TO REDUCE THE RESISTANCE ADJUSTER.
