Openweight, also known as Absolute, is an unofficial weight class in combat sports and professional wrestling. It refers to bouts where there is no weight limit and fighters with a dramatic difference in size can compete against each other. It is different from catch weight, where competitors agree to weigh in at a certain amount without an official weight class. While weight classes are usually mandatory now, openweight competition was the norm for combat sports since antiquity and continues into the modern day.[1]
