>Is the OR gorilla balaclava a light weight model or are their lighter weight options I should consider?
OR Gorilla, size M: 3.8 oz. Not the lightest, but I like it. (I think the OR Windstopper version is a bit lighter, if thinner.) It is somewhat breathable, and with 40+ mph wind and +10F temp I considered adding a windstopper headband over my ears. I like that you can configure face coverage in steps--I especially like the optional nose cover. I wear it with ski goggles and a Buff to cover my mouth. I wear it day and night in cold weather and it hasn't been itchy.
