This mod is working very well indeed, not intruding and yet immersive.
A few things I've noted whilst playing:
Would be nice with a timer before you get totally soaked when getting in the rain. As it is, one gets wet even before it starts to rain

And I dry up almost instantaneously when I get close to a fire (running dynamic with an outdoor gametime of 30).
I really liked the effect when I got into frigid water. Is there a possibility to make the edges of the screen colour faintly when changing environment? I play in 1:st person and so never see the nice shader effects on the PC.
I think it fits with Steel as one of the requirements for making firekits. It's fairly easy to get hold off, but you need to be somewhat prepared.
Running with the whole shebang: I don't see the difference between Iron and Steel, that is, I think Steel armour aught to get minimal protection too just as Iron.
Add the possibility to get a cold when getting chilled. Not that being cold gets you ill but it does tend to make infections brake out easier.
Maybe add one more step for the BEAR or the new WEAR: Minimal, normal, good, warm (or something), going to go through Baratan's Crafting 300 and would find it more interesting with one more step.
Also it would be nice if there where some way to see how effective ones outfit protects against cold.
An essential mod, and very user friendly; good job!
