You don’t need much to start. Borrow what you can for the first few classes, then buy the basics in this order.
Hand wraps
Buy these first. They protect the small bones in your hands and wrists. Semi-elastic wraps around 4.5 metres long suit most adults.
Gloves
For bag work and pads, 12 or 14 ounce gloves suit most people. If you will spar, your coach will ask for 16 ounce gloves for safety.
