Made of soothingly soft, KbT-Certified organic merino wool, meeting Europe’s highest standards. Often becomes baby’s favorite. Natural wool fibers breathe & maintain a comfortable temperature next to baby’s skin in warmth or cold. Wool is naturally flame-retardant, without any chemical additives. Free of pesticides. Wool’s natural lanolin content removes bacteria & odors, minimizing need for washing. Wash occasionally in LANACare Lanolin-Replenishing Soap to maintain self-cleansing effects and to keep wool feeling soft and supple.
