ResproCinqro Mask

Works well. I use every time I run. Indoors/Outdoors_Treadmill, Track, Street. If you run street I highly advise the Cinqro as it will eliminate the intake of exhaust from vehicles 😁😁😁And just being real, Make sure your breath is fresh because the Cinqro will hold the smell, and the start of your next run won't be as pleasant.Somethings could be tweeked a bit. Wick away moisture. Maybe, a over the head strap to keep from having to readjust from time to time. Maybe a border around inside of the mask that would hold better to the skin while sweating. Other than this great mask.

Very bad quality and vendor it's no helpful...Also it's very hard to breath

Great product!
