Atomweight
Atomweight (also referred to as light minimumweight, junior strawweight, junior mini-flyweight and pinweight) is a weight class in combat sports.
Boxing
[edit | edit source]In women's boxing and junior amateur boxing pinweight is, or has been, a weight class for boxers weighing in under 102 pounds (46 kg) (before 2003, 45 kg).
In September 2010 the women's class in amateur boxing was partly merged into an extended 45–48 kg light flyweight division, with women weighing less than 45 kg excluded from competition. Pinweight is still defined for junior contests.
