What is "hogu"

A hogu is the armor worn by practitioners of Taekwondo during sparring. Translated into English, hogu means chest or chest protector. The hogu has been used in World Taekwondo Federation sparring since the 1950s and is considered the most important piece of sparring equipment in the Taekwondo practitioner's arsenal. The hogu is the most common scoring area in Taekwondo sparring. The hogu is hit by the heel, the sole and the top of the foot by many kicking techniques like the roundhouse kick or the back kick, and can also be hit with the fist. Hogus are made by various companies such as Adidas and Dae Do; only certain brands of chest protector are approved by the WTF. The chest protector is mandatory in WTF- or Olympic-style competition; however, it is not used in International Taekwon-Do Federation-style sparring.
