This is a new improved version of the Topliner Contour pad already offered by Tranquility. It is an hourglass shaper booster pad that you use as a 'diaper doubler'. They advertise that is is twice as thick as the original hourglass shaped pad and has twice the absorbancy (27.5oz).
I've never tried the original, but I've ordered the new Super. I like to double diaper, but its a pain in the butt having to diaper, tear plastic, and diaper again. These look like a great (and economical) alternative.
Has anyone tried these?
