I know they don't look like much -- little bags of Cordura, with some straps -- but...
This IS the Pot Shot 2, after all, the revised edition: while simple, the design is also sophisticated. Just the right size for throwing across forty-foot potholes, the slightly-tapered shape helps them empty out cleaner when used stacked for anchors. The outside straps are bartacked for strength, and a strap across the bottom is used as the "cleaning clip-in point" when stacked for anchors. Two belts go around the body, HELPING prevent blowout. (When landing with too great a force, for instance from a great height, the expansive force will blow out the side seams. Be careful how high you throw them from.)
Drawstring top. Uh... well, that's about it.

My first experience in a pothole canyon, Quandary Direct, taught me a valuable lesson. It seems obvious in retrospect, but it is essentially impossible to get an effective toss when treading water in a pothole. It is very important to do the toss BEFORE getting down into the water. For those who have not pot-holed, Quandary Direct in the San Rafael Swell is a good learning canyon.
Pot Shots have been used stacked as anchors, but the SandTrap is much easier to use, and has a much, MUCH larger margin for error. Many will enjoy the discussion on both over at the Bogley Internet Forum.
We carry Pot Shots when using the SandTrap, to carry sand to the Trap when the Trap location is devoid of good sand. Pot Shots are carried as a matter-of-course when there might be difficult-to-escape potholes - basically on Colorado Plateau explorations outside Zion.
Pot Shots CAN blow out at the seams, so we consider two to be the minimum Pot Shot "kit". Long throws necessarily require a lighter Shot. For the longest shots we have used four Pot Shots, each on a separate rope. Climbing multiple ropes out of a pothole can be a substantial athletic challenge, so be sure to bring a climbing 'gun' to do that!
