The 100% untreated virgin sheep's wool inside this overlay regulates moisture and temperature during sleep. Thanks to its optimal air permeability, it never feels damp. With virgin sheep's wool, odours and dirt are unheard of, as its scent becomes neutral again
after a short while in the fresh air. The overlay is attached to the mattress cover by a zip.
