Helps me concentrate not only on my workouts but also my tests practices
One month in, recover after training seems improved, will continue with the product for sure
I own about 10 dive masks, from various very well known brands. Some of them very expensive. Phantom is the only one with no leaks. Also comfortable. Sorry I didn't buy it earlier.
Great gear at a good price
Awesome product, flexible and light that does the job. Jack, Scuba Diving Instructor.
