Fdbro Workout, Running, Resistance Sports Mask Fitness Elevation Cardio, Endurance Mask For Fitness Training Sports Mask 3.0

I bought it in small size because I weigh 61 kilos. Perfect wine in my head and it doesn't fall off. In addition, it is not enough to read in the description but hypoxia levels (more or less breathing force) can be levelled. I'm from Chile and it took like fifteen days, almost no time. It doesn't come with the box the model I bought but great product. For those seeking scientific support in this, the benefits have not yet been supported by science. I don't recommend them for weights. Nor has it been testified that it serves cardio, but I still bought it because of the issue of increasing the strength of the lungs and emulating tiredness very well (for those who compete) Greetings!

The quality of the norms, the cover came with a carabiner, but I doubt that it needs to be clung to the rugzak outside, especially in winter. The book is in English and Chinese. The mask can be disassembled and replaced by an elastic band, but how to do it HS, since I do not know Ang. It is a pity that the mount on Velcro, through time can not glue. The cover is steep, dense, it will live longer than the mask).

The product is exactly the same as in the photos and videos and has been quick to arrive, as I thought it was going to arrive on August 30 and the 18th, that is, he's come in a lot of time. It is super comfortable and fulfills its task perfectly. I give you 5 stars because it's the most you can, but from 0 to 10 is a 10.

Excellent, good quality! I like it! I may order more! But the elastic looks like it's not durable. I'll keep commenting when I give you good use.

If you put the filter at the valve can be used as a stylish protective mask. The minus is poor audibility, as the voice sounds like a barrel

Filter, creates strong resistance and 1st level as the 5th. Kill m filter and everything works as needed!

Smells a little bit, but overall this is very good equipment for extreme performance
