Review on 🏋️ Vikingstrength Adjustable Resistance Workout Mask with High Altitude Elevation for Running, Biking, MMA Endurance and Air Resistance Training by Dave Neal

I have a few training masks from other companies and honestly this is the best mask I have ever tried! Very comfortable to wear, didn't slip or move when doing my HIIT workouts. There are two switches on the front of the mask that set different levels. This was a game changer for me as I was able to adjust mid-workout without removing the mask or inserting or removing the valves. The mask is very light compared to my other two masks which makes it more comfortable when exercising. I highly recommend this mask! And the price is worth it!
