All set for some winter riding, 40 to 60 miles every other day.
Except I seem to really get knocked down after a cold ride because of lung irritation, and the resulting coughing and phlegm.
I've searched high and low, items are either expensive, or just don't work. The WSJ had an article a few years ago but all three companies are closed.
I just bought some cone style surgical masks. After a little modification I will try one on a walk tonight.
Any suggestions?
