Snug Sleep uses superwash wool in these washable mattress pads. Wool is very absorbent and can wick moisture away with out feeling damp. This helps you get a good nights sleep and prolongs the life of your mattress.
The wool goes through the "Hercosett 125" shrink proofing prosses so it can be gently machine laundered when needed. They do not use a chemical freshener after so some uses might find they have a bit of a smell which will go away with time and washing.
