I wear this over my mouth when cycling in the cold - and it keeps me from coughing. I found that when cycling in the cold I need an inhaler to stop my perpetual coughing: this keeps the air warm enough for my lungs so I do not need an inhaler. If it is really cold, I put it over my nose also. And it obviously keeps my ears warm too! And thin enough to wear comfortably under my helmet. So glad I bought it. Washes well; dries quickly. I have bought one for my mother too - she loves the versatility of it.
