Great balaclava. I purchased to keep my ears and face warm while biking through the Boston winter and this product does the trick. It fits snugly, but not so tight as to be uncomfortable. So far I've biked with it in temperatures as low as 22 degrees F, and have had no issues keeping warm.The only reason I didn't give it 5 stars is because I wear glasses and did have some trouble with them fogging up from my breathing. The material is fairly breathable, but I found that covering both my nose and mouth resulted in significant fogging. On the other hand, if I only cover my mouth, I don't have any fogging issues. I plan to manage nose coldness by tactically raising and lowering the balaclava to manage the fogging.Long story short, if you don't wear glasses, you should seriously consider this balaclava; if you do wear glasses, I'd still recommend, as the fogging can be circumvented in many cases.
