I looked at so many running masks and all the reviews and finally settled on buying this one. Mostly due to the price and the other reviews. I have used the mask for running outside during winter to help protect my face from the cold and breathing in the cold air. I have used it a few times now and I have to say I really like it and satisfied with the purchase. Its light weight and it does not get too hot or too cold. It covers perfectly around my head, nose and mouth. I do put a hat on over it and it works great. My only problem with it would be that sometimes the fabric bunches up under my eyes and if I'm running for long periods, the mouth area does get moist from breathing but not to the point where its bothersome. If you are looking for an affordable and effective mask for outdoor winter activities this Mask works  great and I would buy it again.
