The Restop® 2 uses a patented "bag within a bag" design to safely contain and neutralize human waste. Restop contains the odor as well as the waste. The outer bag is a Mylar gas-impervious bag. The same polymers and deodorizers used in the RS1 are inside, with a slightly different set of enzymes for solid waste. The Restop 2 system contains the odor as well as the waste, providing a user-friendly and pleasant means to pack out solid waste. Ample toilet paper and a moist antiseptic towlette are included.

How is it used? The Restop 2 is designed to be used with any commode system or can be used directly on the ground in wilderness situations. To use with a commode system, simply insert the Restop 2 into the commode bucket and fold the upper bag over the foam toilet seat (bucket and seat sold separately). When done, the upper bag folds into the lower triple layer barrier bag which then zip locks closed for complete containment. Now the waste is safe for disposal in any trash container.
