Friends Of Pinnacles generally does NOT promote products or services unless they are non-profit and climbing related, but in this case I think we can make an exception:

With the many long hikes at Pinnacles and the lack of bathroom facilities, waste displosal is a serious concern. We all know that we are supposed to pack out our waste, but how many of us really do that?

Restop's new Waste Containment Pouch actually makes packing out waste doable. Not only can you contain the waste, but the smell as well. Inside the bag is a powder, a polymer/enzyme blend, which biodegrades and gels the waste, giving it EPA approval to be simply thrown in the trash after use.
