I have run hundreds of miles with these masks on. Works perfectly. I always have a few ready incase the weather gets cold and windy. I can breath easily with them on.
These masks are awesome. My biggest piece of advice is to have two masks because after about 25-30 min of sustained cardio, one mask will get pretty sweaty. Only one mask is needed if you are just weight lifting.
Till now the best masks I ever had .. You can breath normal with and i am protected .. Thank for this really good Item
The mask is breathable, fits well and easy to use but some issues are it still goes in and out of mouth when speaking . I would recommend this mask because compared to others this is top notch and masks stink.
