This kit is for night temperatures that go to slightly below freezing (but not much)

What do you think?

I've lived in a tent/outdoors for the past year and a half including in temperate winter (-5 degrees celsius) or something so I'm not just larping, I'm considering switching to a heavy-fur loadout because the few fur items I have are very comfy and cozy. I have a homemade fur jacket and fur pants and I can lay down outside around freezing temps on the cold ground without even feeling slightly cold. Similarily my homemade fur hat changed my winter nights from freezing cold to kind of okay, so it makes a big difference.

A sleeping mat is handy because I don't want the furs to get needlessly wet, and if the ground is cold and wet I think even furs won't help you enough, so it's just as a barrier layer for the moisture and not really about the warmth it provides.

The big reason why I like this setup is because I think you can get through temperate winters without much of an issue temperature-wise in such clothing, so you don't have to bring a sleeping bag and you can wear these clothes as your regular outdoor clothes in colder temps making for a light backpack.

The raingear is quite neccesary for furs in temperate climates, because a real torrenetial rain will make fur clothes uncomfortably heavy and might make it lose it's warm quality.

Questions:

Do you know if fur retains warmth when wet like wool does?
