A one size hemp doubler made with 4 layers of organic cotton/hemp fleece.  13 inches long and 3.5 inches wide, it fits perfectly in between our hemp inserts, or underneath the quick-dry soakers of our fitted diapers.  Expect some shrinkage in length.  Doublers are used to boost the absorbency of your pocket inserts, fitted diapers or prefolds.  Because these doublers are not wide and long enough, they are not meant to be used alone as inserts in pocket diapers.
