The nylon combines with a special backing to give the robe modesty. The culotte design will not float up. Some churches use their robes for baptisms in the open where converts walk in view of everyone to and from the pool. The one-piece design allows converts to remove his or her clothing, step into the robe, zip it up and enter the baptistery in seconds. Afterwards, they come back to the dressing booth, slip off the robe, hang it on a hanger, dry off and get back into their clothes in a couple of minutes.
Water simply beads up and rolls off into the pool.
Very little water is carried out of the pool. Do not dry clean. Do not dry in a home or commercial dryer. Heat can age the nylon and separate it from the special backing. Avoid any bleach.
