It's 33% heavier than other water bags, making it super durable - plus its valves are easy to fill up with a garden hose. Keep your winter pool cover in place to keep out debris and dirt this winter with these double water tubes.
Surprised. I was expecting a lesser quality. I used 14 out 15 and not one of the ones I filled leaked. Plugs closed easily. Seams were well bonded which is where most leaks occur.
