This thing doesn't cut it when it gets really cold (< 10 F). The perforations and cuts that allow for breathing also let the frigid cold in. Plus, it's really inflexible when you need to pull it down when inside a gondola or a lodge. Definitely don't recommend.

Better half & I have been trying different combinations of headgear to ski comfortably in freezing temps for decades. Decided to try this Combo Clava as a one quiver solution to wear under our helmets. Trolled the 'net looking for how to best pick the correct size. Best advice was from a site that recommended measuring around the head from the middle back of the head to 'just under the nose' in front. In spite of rather differently shaped heads, we both came in at approximately 22". According to the Seirus size chart provided by BackCountry.com, this would put us right in the middle of the S/M size.
Upon arrival we tried them on and found they did fit, BUT after wearing them for a few minutes, with & w/o our helmets on, a definite unpleasant pressure on our noses was noticed. And then we pulled the head-covering back to wear it as a 'face mask only' and it was obviously too tight. Checked the size chart yet again to find that 22" is within the very lower range for the L/XL. So they are going back for an exchange for said L/XL. Hope they are not too big around the eye area where the goggles are supposed to fully cover all exposed areas. We shall see...soon! Love the free 2-day ship :-)

I absolutely love this thing. I was surprised to find that when you cover your face with the mouth part you don't get that typical clammy feeling, which is nice if your like me and, even when it's freezing cold, don't like to put your head in the hood part of a sleeping bag. For the price you can't beat this, the only quarrel i have is that if you wear sunglasses with this on they will fog up but this is to be expected.

Great product. Keeps you nice and warm while letting you look like the ninja you always wanted to be.

I bought this mask during a trip to Solitude when the mercury dropped to -14 this year. Amazingly, this mask kept my face toasty and dry, much to the jealousy of my friends who were wearing iced-over bandannas. It fits under my helmet and I forget I'm wearing it. Get two.

These items were ordered for the loading guys I work with. They work outside much of the day, and during the winter it's cold. Most of the guys have come up to me and said these are the best they've ever had. Previously the full mask has been a knit one, and not as warm. Excellent item for anyone who spends a lot of time outdoors during winter.
