Our HumBird ultimate inserrts are crafted from a top layer of 100% organic cotton sherpa and two layers of super heavy hemp-bamboo fleece. The ultimate insert booster is meant to be a stand alone insert it is so powerful. Of course, you can always combine it with your current insert system but it is so extraordinary you probably won't.
The top layer of sherpa absorbs quickly to ensure leak free absorption no matter how fast your little lets go and the two layers of 500gsm 55% hemp 45% bamboo give an absorption power like no other.
***Inserts will shrink in hot water. All fabrics have been prewashed and dried so shrinking should be minimal.*****
