The term CATCHING AID is composed of two words, 'MITT' and 'NET'. A MITT is a type of glove used in sports such as baseball, softball, and cricket to help the player catch the ball. It is usually made of leather or other materials and has webbing between the thumb and forefinger. A NET is a piece of equipment used in many sports, including volleyball, tennis, and badminton, to catch the ball or shuttlecock. It is usually made of nylon or other lightweight material and is held up by a frame. Together, these two items form a catching aid, which is used to help players catch the ball or shuttlecock more easily.
