This is just my input as someone who owns several different garments that are similar to what one will find in UrW, and the following is a list of what I have IRL with the weight of each item in kilograms and pounds:

Wool Cloak-7 lbs or 3,1 kilograms

Wool Tunic-4 lbs or 1,8 kilograms

Wool Trousers-3,5 lbs or 1,5 kilograms

Wool Leggings (pair)-2,6 lbs or 1,1 kilograms

Wool Kaftan (overcoat)-6 lbs or 2,7 kilograms

Wool Hood (two layers)-1 lb or 0,5 kilogram

Wool Hood (one layer)- 0,6 lb or 0,2 kilograms

Wool Mittens (one layer wool, one layer linen)-0,3 lb or 0,1 kilogram

My only garment that is entirely made of fur is a cloak made from the hide of an adult male whitetail deer; it covers my shoulders and torso completely, the length is just above my knees, and it weighs in at just over 12 lbs or 5,4 kilograms. I'm not sure if elk or reindeer hide is heavier or lighter than our regular deer hide so I don't know if that is really relevant to this.

The wool garments in-game, however, seem to be quite accurate when compared to what I have IRL. Of course, comparing my garments to those of the Iron Age, even though I've done my best to follow traditional designs, methods, and materials, could be considered anachronistic and irrelevant.
