I bought one of these for work, after using an awful acrylic one that made my neck horribly itchy, wet, and just made me an all around angry person!The Smartwool neck gaiter is not itchy (as long as you have no wool issues), keeps relatively dry (even if you have it over your mouth), and frankly just looks a whole lot better.I should mention that I was using it for temps between 5C to -25C, day in day out for a couple of months. Definitely pulling it out next winter (great for cold weather running!). Thinking of getting another one, as I did not know how many colours/patterns were available.
Exactly what it is supposed to be - soft and warm. Just the thing when the weather turns cold. Stays warm when it gets wet and doesn't irritate even when worn for days on end. If you have a wife or girlfriend, get 2 because she will appropriate the goodness.
