I Have An Everlast 100 pound Bag And Its Pretty Good to Me And it Only Cost Me 80 Dollers

But Im Not Sure Cuz The Punching Bag And A Few Pairs Of Gloves Is All I Have But I Think Everlast Has A Guarantee Dont Know If All the Other Brands Have Guarantees Or Not But My Bag Had Like A Waranty Or Something On It ...
But Im sure Other Brands Are Just Fine
