Decisive Fitness Training Mask, Workout Mask

It is not genuine , box was not carrying companies name , quality was not up to the mark , elastic was already loose . Even medium size is not sticking to the face , it’s slipping while practising

Band quality is bad

I love this product, it has made me have to relax more and concentrate on controlling my breathing

Awesome stuff to work on your rhr .... Resting heart rate ... ❤️
