Heavy, black, stable and looks really nice with the label of evil! Sturdy fabric. The material is a little rough, with bare fists can easily happen that you, the chafing what if you do not meet the bag centered. As a leather or plastic bag is gentle, but certainly much more sensitive. Gloves or better training gloves are recommended. The stuffing is quite heavy and solid. For boxing's very good at kicks acts sometimes quite massive. For sensitive shins and instep cushion I would recommend fastening straps. The hook on which the four chains are suspended, is pivoted so that the bag can swing in and turn freely with strong momentum. Perfect!
