I'm one of the people that prefer the mask (in my case the Airtrim [0]). I had problems with it getting to humid inside the mask too before I learned that if I just blow (hard) out once every 10 minutes or so most exess humidity will be blown out of the filter and there will never be a buildup inside of the mask. I can really recommend getting one of these heat/humidity exchangers, I think both types of products will do the job. I had to give up many winter sports due to problems with the cold and dry air before I got my Airtrim. Now its like breathing in +20C all the time. Best 50$ I ever spent.
