Wool is the spun fleece of sheep, and fiber diameter decides how it feels — finer wools like merino are soft enough for next-to-skin wear. The crimped fiber traps air and can absorb up to 30% of its weight in moisture before feeling damp, which is why wool keeps insulating even in light rain.

Why does wool keep you warm when wet?
The crimped fiber traps air, and wool can absorb up to 30% of its weight in moisture before it feels damp — so a wool jumper keeps insulating in light rain where cotton would feel cold and clammy.
