The regular white nursing pad is constructed with 4 layers of 100% cotton birdseye diaper cloth and 100% cotton diaper flannel; Chosen because the natural fiber fabric has minimal processing and no added chemical finishes. Average 4 7/8” diameter. Works just fine for most women with average or light leakage.
The natural pad uses unbleached birdseye and unbleached flannel: Less, if any, processing and no finishes. Nice coloring subdues under white shirts.
The black front is the 4th layer using cotton interlock or jersey. We cover a white pad because dyes used in the black flannel interfere with absorbing. It can be worn either way out – black or white.
