3-pack of Buttons' daytime inserts Super slim yet super absorbent  Buttons’ hemp/cotton daytime inserts are made of 4 layers of absorbent 55% hemp & 45% organic cotton, with a layer of moisture-wicking fleece on top.  Buttons cloth inserts snap right into their covers to keep inserts from shifting around.
