How to add warmth to armor parts?

[N.Gamma]

Can someone explain to me how to add warmth values to armor pieces?
I have an armor mod that adds some nice fur parts to the game, but unfortunately most of them don't have a warmth value, which is needed with SunHelm against the cold.

Is that somehow possible via key words or something?

Keywords, yes. SunHelm uses survival mechanics, right? I don't think it supports Frostfall coverage system. Survival mode introduces the following keywords to assign warmth to equipment:

• Survival_ArmorCold
• Survival_ArmorWarm

I'm not sure if you can assign a specific coverage value. In any case, you can check this article about adding FF/Survival keywords to armor pieces. Give it a try and if you need an example look for survival patches that already do that for other pieces of gear.
