I like how easy it is to adjust air circulation on the run. It doesn't move while running.

the mask is comfortable and it feels very secured on the latch and it wont come off

I didn't think it would be so comfortable in my face. Definitely build for the task.

It's either way to weak or just way to strong. More settings an ideal product.

Excellent i been using a lot worth it
