Sparthos Workout Mask - High Altitude Elevation Simulation - for Gym, Cardio, Fitness, Running, Endurance and HIIT Training [16 Breathing Levels]

Has nothing to do with the picture Too small The levels make absolutely 0 difference. Absolute waste of money.

Not heavy, and have multiple levels

Exacte a la description du produit et arrive comme prévu dans les temps

Just got back from 5 miles of roadwork. This product is legit. As soon as I took it off, I noticed my lung capacity increased. I feel amazing and after the first use of this product, I can already tell you this is absolutely worth it especially for the price. The size is fine I have a big nose though so it kinda is annoying pressure absolutely amazing mask it’s kind of hard to believe how they can sell something so good for so cheap. I appreciate companies like this. Not to mention how beautiful the Boxing and the case is. Very impressive design! If there is any product out there, that’s beneficial for the people at a good price. This is at the top of the charts.

Excellent masque, fit parfait

Excelente producto 100 por ciento recomendable
