Disana wool covers an excellent alternative to synthetic covers, wool soakers are naturally antibacterial and provide excellent moisture regulation. Wool wicks moisture away from the skin and can absorb up to one third of its weight in moisture and return it to the environment. These covers can be used over any pre-fold or fitted cloth diaper, and the high knitted waistband provides a nice fit over any type of diaper, no matter how bulky or high-fitting the diaper is. This soft ribbed waist band also keeps your baby’s tummy and back warm and cozy throughout the night. Made in Germany.
