I had a hard time getting comfortable with the balaclava on. Is yours fleece(balaclava that is)
I think it's also important to point out that Shug -being in Northern Wisconsin - has a different definition of "cold" than most.
I have a polypro balaclava for the hammock that doubles as a motorcycle helmet liner.
I've also used a silk Wild Rag (modern cowboy 36" bandana) which works very well in the hammock. I put it over my face like a bank robber.
There is a secondary benefit to covering your mouth... your mouth doesn't dry out as bad in winter. I tell my body to breathe through my nose, but often I will wake up and find that it breathed through my mouth, and I need water bad!
I like the idea of a balaclava but when I wear one I end up using it like a beanie anyway - start to feel trapped in it.
I think my momma should have named me Claustrophobia.
