Awesome masks! Easy to wear and rests around your neck instead of hanging from your ear. This order is a reorder! That’s how much I like them!
Verry useful Can breathe with its
I like it better than the S1 mask that you offer. It's comfortable and stays in place
It is difficult to breathe during high-intensity exercises.
I have the S1 and the S2, The S1 is a much higher quality product. I love the material of the S2 but it’s made so cheaply that three weeks after using it one of my ear loops ripped off and then a week after that the nose piece came out. I only use this for lifting weights in the gym. I don’t even use it for high physical activity. I would suggest buying the S1 over the S2 anyday. I reviewed this product before but doesnt look like they published my review.
