I always had condensation problems with my eyewear when biking in cold weather. 50% of visibility due to the fogged up glasses can become dangerous on the road. I tried Microclair Sports products, and it really works! No more condensation problems! I keep a perfectly clear vision all the time. So I definitely recommend this product to anyone who practices outside sports, particularly in cold weather.
