As wool absorbs water molecules it pulls moisture away from the skin to the surface of the fabric where it evaporates.

Does wool shrink in water?

Water alone will not shrink wool. Wool expands slightly when you submerge it in water as the fiber absorbs the water. It will return to its original size as it dries as long as you don't add heat or motion. Hot water can shrink wool, but only if you also agitate the wool.

Is wool the best insulator?

In dry conditions, wool is only slightly better at preserving warmth, but when both materials are wet, wool offers much better insulation because those scaly fibers allow for more air pockets to remain within the fabric. These air pockets are instrumental in keeping warmth from escaping through the material.

Is wool environmentally sustainable or friendly?
