Now you can practice a correct uppercut and well-placed hook on any standard heavy bag with the TITLE Boxing Heavy Bag Striking Mask. The realistic, anatomically correct face is made from durable, molded sponge rubber foam that helps increase focus and provides a perfect angle for the uppercut and hook. The bag has a simple, wrap-around design with a D-ring closure that prevents slipping and secures the mask tightly to the bag and allows it to be taken on and off easily.
