im not exactly sure what is in mine. its a cloth everlast bag. white. with black writing,it has like chopped up looking cotton stuff on top as far as i can see but its hard at the bottom cause whatever is in it packed all down and the top is now flimsy.it feels like sand.
ive looked around. maybe ill have to deal with a 120LB one. are water filled bags any good? its leather i guess with a water bladder . or are they junk?
You can fill your bag with rags or cotton filler( I sent to a serta factory near my house). I filled my old bag a 1/3 of the way up then added foam then more cotton, foarm, cotton. Until it was full. The foam keeps the rags/cotton from settling at the bottom.
i think the water bags have just a water bladder core and are surround by foam i heard they are good on your hands and feel more like an actual person but i dont know about longevity anyone here use one?
