Weighted Clothes

Weighted clothes are clothes fitted with built-in weights to make them heavier than ordinary clothes. 
Weighted clothes are used by several warriors throughout the series. 
Weighted clothes typically suppress 20-25% of a warrior's full power while training. The mass of the weights can be increased to gain more power. Weighted clothes generate similar results as gravity training, but are limited by how little they can increase the user's weight in comparison. Weighted clothes are more versatile though, because they can be used to gain immense power on even low-gravity planets. More importantly, weighted clothes can be used alongside gravity training, for example when Goku trained on King Kai's planet, and when Piccolo trained in the Hyperbolic Time Chamber.
