I basically took a whole bunch of ripped underjams and goodnites, and stuffed a Medium molicare to the brim.
I normally wear a small, but the order I recently got also came for some reason with a 14 pack of the Mediums. I decided to use them as stuffed ones, as they normally will not fit me.
To put into perspective the thickness of this monster, a normal goodnite at it's thickest point is around 1/4 in. This monster, comes in at a full 3.5 in!
