Staying warm when glassing

[Formidilosus]

Anything you add changes that 37F for static use and depending how you layer, significantly changes that. Hopefully I’m making sense.

No, it really doesn’t. Doubling up 2x 5oz fill puff jackets is not the same as an equivalent 10oz fill jacket.

Please share your personal experience using these jackets in true cold weather, and how that relates to the CLO numbers you reference.

I never said it was the same as a 10oz fill. I said you could double up, and it would add insulation in lieu of another mid layer. Yes it still adds CLO even if the loft is more comprised.

My experience is I put on a UA ridge reaper parka, and good layers, went hunting, glassed, and was fine in single digits. On a few occasions. As far as my core. My feet and hands were another thing. We are talking jackets though.


How is my experience related to CLO? Because I know how to layer. We will go back to the example of the Kuiu super down burner parka. Tested at 2.23 CLO. The layers were like a t shirt and stuff. Without them the jacket is like 1.70

A heavy merino shirt 260, the strongfleece 290 and the parka would ALL be about 2.53 CLO at 1 MET. Failure right?

Is it?

1 MET is like a statue. I don’t know about ya’ll but I fidget some when I glass. I move my legs. I stand up when my back hurts from sitting. That’s not 1 MET. If You estimate realistic glassing at 1.2 or 1.3 MET, the math starts to change.

Additionally, for every 1 milimeter or something of air space between layers it’s like .16 CLO. For 9 degrees freedom, you need about 3.19 at about 1.3 MET, and 3.65 at 1.2.

It’s doable. Especially when you’re NOT sticking in the Kuiu line for these examples. If you actually try, then you can find things like mountain hardware’s monkey man fleece which has .62 CLO vs Kuiu’s StrongFleece at .4 CLO. Sticking with a 260 merino at .4 CLO.

The Sitka kelvin aerolite’s special tech in their primaloft gives it a solid .95 CLO even if you compress it. Unlike if you double up on down I mentioned earlier. Now we are starting to get to a usable number and there’s other things you can do.

But what do I know.

You wore one jacket on a few occasions and are in here arguing CLO and layers?

To anyone that has spent real time in cold weather- what you are writing seems to be “but one time I read”, not any actual experience.

Neat. Notice in all of your CLO’ing, you didn’t address what temperature that all of your clothing that you suggested allows you to remain motionless for hours. It seems like you can’t answer that because you don’t actually know because you haven’t used them, and haven’t spent much time outdoors in real cold- if this isn’t correct, please illuminate.


This is a prior post of yours about cold weather clothing-


So do you wear a base layer, one mid kayer, and a puffy? Or do you “CLO” up and layer multiple mid layers, multiple puffies, and move around to stay warm…?

A clue is… a jacket that has less loft than a 0° sleeping bag isn’t a 0° jacket when stationary glassing.

But what do I know.

I don’t know- I am trying to figure out if you have relevant personal experience with this subject or are you just regurgitating numbers and figures from a catalog? Nothing you have written says “my experience is”.

Fair is fair- it takes very little looking to see that I spend a lot of time in very cold conditions outside doing exactly what is being discussed, with a variety of clothing, and with dozens of others doing the same.

@Formidilosus do you have a rough pricepoint on that down parka?

I have been told $400’ish.

If I have room in the pack for it, I like a hill people serape. Super easy to put on and take off over just about anything and keeps me nice and toasty. I love that stupid thing. Only problem is that it is quite bulky in the pack.
