Review on Polyform A-Series Marine Buoy by Jack Duncan

This is a great alternative to a teardrop water filled bag! Saved a lot and it works great for what I use it for (boxing and striking). For the people who are looking at this as a striking bag, keep in mind that the temperature has a lot to do with the hardness of the Buoy/Bag. The colder it is, the harder the bag will be (to the dangerous level). It could be hitting cement!. I filled this about 70% and as the temperature gets warmer, it's softer and more realistic to the fell (of hitting an opponent)
