The standard answer will be the space between the wool fibers traps air and insulates, thus keeping you warm. Also, the wool fibers are non-absorbent, so it won't absorb your sweat and become clammy and cold. However, there is a strange property of wool that makes it just warmer than high quality synthetic base-layer (underwear), even though the synthetics have all of the above properties. I personally think it is the scratchiness of the wool that makes the difference. I don't care how soft or how high the quality of your wool underwear is, it just feel different to the skin. I would say it is not smooth and not as comfortable, but the unique sensory input makes me feel warmer compare to a synthetic shirt with identical thickness. I can't explain it, but it is true. I heard old school climbers would wear those scratchy clothing just for that warmth benefit.
Wool fibers are hollow, which draws moisture away from your body like a polar bears fur.
Wool is a bad conductor of heat so when we wear a woolen cloth it does not allow the heat of our body to go out and it keep us warm.
Its just because woolen clothes have fibres and between those fibres air is trapped which reduces heat loss. Air reduces heat loss because it is an insulator or poor conductor of heat.
