Asthma causing you difficulties in cold weather?

Do you suffer from asthma? DO you have difficulties with cold weather? I had them for years and I did not know about this producer, and nobody gave me the information. Now that I have it, and have used their thermal mask, and have bought one for my son and one for my mother and we can all move freely out in the cold in spite of our asthma - my son cycles to work in -18*C without problem - now I want to share this information with everybody because it is so essential:

Get a thermal mask. There is a producer. Here is the website:
