I tried wearing a possum fur beanie this weekend on a windy, 36* ridgewalk, and while camping in a bivy around 40*. The beanie is by far the most comfortable I have ever worn, but as others have noted, it's worthless when a wind is involved. The wind cuts right through, and chills my ears even though there is a doubled layer of fabric over them.
This leaves me in an awkward position.
Having a large head typically means that I can't comfortably fit into the Windstopper watch caps that everyone else wears. These seem to be the lightweight method of keeping a head warm. The possum fur appealed to me since it is double layered, stretchy, and thus would comfortably fit over my head. What now? I've heard people recommend the Integral Designs Primalid, but I'm worried that this won't fit either, even though they do offer a 'large' size. Do any companies make these watch caps in larger sizes? Surely someone else on here has a large head with a lightweight, warm, beanie.
Second: Can anyone compare the warmth of using a thin watch cap with windsopper fabric with another thin balaclava to wearing a thicker beanie only, like the Primalid?
