Love Love Love these and will be ordering another set for my mom and I. I can talk on phone, bike, rapid walk, run, jog, hike, and more and still breathe. LOVE the material and the description is accurate these mask are made for such sports and more! I can wear my disposable filtered face mask for extra protection under it when shopping and walking outside doing chores around area and home. THIS IS SUCCESS! So far I've ordered other mask and had to return them because of the material is breathable friendly and you can't talk, walk, bike, hike, jog with out it falling, slipping moving off nose and mouth area and more importantly can't "breath" with/without filters. KEEP UP GOOD QUALITY WORK!!! Thanx so much!
