Cold face when sleeping

I just tried a Patagonia Capilene 4 balaclava for cold weather camping It was fantastic. Enough warmth to keep the chill off, but breathable enough so that I could actually breath if if I pulled it over my nose and I didn't wake up sweating. Any Power Dry balaclava should work.

Cap 4 beanies are also fantastic. That fabric has an uncanny ability to cover a wide temperature range and keep your noggin warm without getting wet from sweat.

I like to wear a Buff over my face. The Cap4 Balaclava is also great but if it's cold enough my eyebrows and eyelids start to feel cold.

Picked up a poly balaclava from the Army/Navy surplus store. Really thin (think warm weather athletic T-shirt) polyester/spandex material. Cost me $7, weight is 38g. It's my primary headware when I'm out in temps below 45*; I can wear it while moving, since it's thin enough to wear under my visor and dry just as fast as my skin. I supplement with burlier hats (usually wool) as needed.

Been meaning to try and make a fleece version for sleepwear (would help cut down on needing neck warmth when it dips below freezing), but I've been lazy over the last year, so…

You have your hood cinched up forming a tiny blowhole? +2 on the buff.

At Enlightened Equipment we make the Hoodlum- Climashield Apex insulated hood, pretty adjustable so if you like it more up on your mouth/over your eyes or more loose than that, it's pretty simple to wear it the way you like it. ~1.55oz for the 20-40°, and about 2oz for the 0-20°F. Can be a little goofy looking, but I find it really comfortable and pretty easy to use a few different ways depending on conditions.

Edit: My profile photo shows one of the ways to wear it, as an example.

Dr. Jordan, at one time, modeled sleeping in a hoody (Cocoon) that he was wearing backwards. It has enough volume to avoid intimate contact with the face, but does indeed provide full coverage.

My sensitivity to CO2 does not allow me to do that.

YMMV.

I think the other posters have directly addressed your question with some good suggestions.

Here's an indirect answer.

Sleeping in an all fabric inner tent with all the mosquito netting openings (e.g. windows) covered makes a big difference. If it's 20F outside it is usually 30-35F (or more if moving) inside. Plus there is no breeze on your face.

Smart wool neck gaiter pulled over face

It saves my life

Only a cold face and no soar throat from breathing dry air ?

i usually throw a shirt or jacket over my head and call it good. loose enough to not feel constrained but encloses so the air warms up

Smartwool balaclava inside either a fleece or 6oz/yd PL/1 balaclava (depending on expected temps) The EE hood would be a great outer balaclava

The outer balaclava closes enough to insulate forehead, chin and cheeks. The inner covers my mouth and nose … easy to breath through.

One of my favorite pieces of gear is the Seirus Quick draw hat. It is a 200 wt. fleece hat with a 100 wt balaclava/face mask that pulls down or stores in the tip of the hat when you don't need it. When my nose gets cold at night or in really cold or high winds when walking it is right there.

Do you use a quilt, or a bag?
I use a quilt, and have the Goosefeet hood sold by ZPacks for temps like that. 42g/1.5oz.

Glamour shot alert! :o

Owen you look like a dementor! Cozy however!

I just pull the "covers" over my head. Then again, I've never been in temps under 20 degrees. ;^)

Sorry. Bit of a "perspective" pic. In real life, the hood looks bigger..and I have no trouble fitting through doors and stuff.
