The Restop RS2 uses a patented gas-impervious “bag within a bag” design to safely contain and neutralize human waste. The same polymers and enzymes used in the Restop RS1 are inside, with a slightly different set of enzymes for solid waste. All RESTOP bags and assorted other products are unisex. They can be used by anyone, any age. The bags are landfill-friendly and have been approved by your state’s water resources board for landfill disposal – they are similar to baby diaper disposal. Ample toilet paper and a moist antimicrobial wipe are included.
