Works like a charm! You really don't start to feel the effects until you start raising your heartbeat a bit.

Controlled my breathing fits comfortably definitely works for weightlifting and running haven’t tried cycling yet

I liked it a lot, it's a good product, the only bad thing is that when I get to, my house had opened it, the duana de mi pías, but the truth was a good product

Durability and strength, good product. It's also comfortable.

i love it would buy again I recommend it and arrive in time and form despite being international shipping

This mask is the truth I use for every cardio session I do and even while working out I have it on. The first couple weeks I was dying but it was worth it cause I’m going harder than I was last month

It’s so. Comfortable, and it’s great to go outside, you can wear it to protect your self from COVID-19 Virus, and it’s very comfortable to wear it long time without bothering you , it’s fit as the description
