They were given by my dojo for sparring. Is it suitable to use for a punching bag?|||You should use only bag gloves or boxing gloves with your hands wrapped to hit a heavy bag.





These tkd gloves are designed only for touch contact not for the strain of heavy bag hitting.|||Nope, don%26#039;t use those!! For using a heavy bag, you need at least 12-14 ounce gloves and hand-wraps to protect your knuckles and wrists. These gloves don%26#039;t look like they offer any support to the wrist area at all. Not good if you train on a heavy bag.
