Thanks for the reply. All the Everlast canvas did lasted 2 years. It is made of very heavy canvas. But the Tuffwear lasted one week each!!! I don't think it's defective because I exchange to another from Big 5 and it ripped in one week. I practice at home bare hand punching and bare feet kicking. I thought this is normal that people break their bag every year or two. I have not been to school of a long time already but I have been consistently doing rounds every week for the last 30 years as aerobic exercise. I don't know how heavy I punch, I am too old to worry about it, but I did break quite a few heavy bags. Now I stuffed my bags hard to make it last longer now. Yes, the leather bags last much longer, Big 5 was so embarrassed about two broken bags they gave me big discount to buy a leather bag, I stuffed it harder and it did lasted 4 years before I worn through it. I have a 100lbs leather bag on one side. My 70lbs Everlast canvas on the other side is getting old and I need to replace with a canvas to toughen my hands with the canvas. I am just surprised Everlast stop selling the white canvas bags anymore. currently, I am looking at Tittle black canvas bag, I just don't know how well it stand up. Thanks
