Weighted clothes are clothes fitted with built-in weights to make them heavier than ordinary clothes. Weighted clothes are used by several warriors, most notably Piccolo. Goku uses weights at the end of Dragon Ball in the 23rd Tenkaichi Budokai and during the battle with Raditz. The weaker Z-Warriors use weights to train for the arrival of the Saiyans at Kami's place. Finally, Pikkon demonstrated his use of weights during the otherworld tournament against Goku.

Weighted clothes typically suppress 20-25% of a warriors full power. The mass of the weights can be increased to gain more power. Weighted clothes generate the same results as immense gravity training. Weighted clothes are more versatile though, because you can use weighted clothes to gain immense power on even low-gravity planets. More importantly, weighted clothes can be used alongside gravity training, like when Piccolo trained on King Kai's planet, and when Piccolo trained in the Hyperbolic Time Chamber. The latter was especially effective, as Piccolo nearly tripled his fighting power, surpassing Semi-perfect cell

As time went on, weighted clothes became less significant in battles. Goku never even bothered to take his weights off during his stalemate battle with Perfect Cell.

The battle in which weighted clothes made the most difference was when Piccolo fought Freeza's second form. After the assimilation of Nail, he was already fighting evenly with Freeza. Finally, he took off his weights, became almost 25% stronger, and dominated Freeza's second form, a feat that no other warrior had ever done before, Saiyan, Namekian, or otherwise. This is what pushed Freeza to display his previously unseen 3rd form.
