Timothy B.wrote a review of SmartWool NTS Mid 250 Balaclava on February 26, 2013
Feels great. Fits well. Very transportable. I carried it in the pocket of my pants when not in use. When needed, it is versatile--it can cover:
1. Just your neck
2. Neck ,top of head, sides of face
3. All of above and chin
4. All of above and mouth
5. All of above and nose
Making a quick transition between the areas of your face that are covered is essential when trekking in very cold temperatures, as your perceived temperature changes every minute depending on whether you are walking/climbing/resting and on whether the sun is blocked out by clouds, ridges/cliffs, etc. Transitions are fast with this balaclava. And the wool feels great. This is a thing balaclava, but I never felt that the warmth provided was not enough. Served me well on Mount Kilimanjaro, and likely will on many more trips.
