Overview

These weights come from Mei Hatsume, whose design took first place in a competition held to source them. Extreme compaction is the trick that makes them practical, since it shrinks them to something a person can strap around an arm or a leg without difficulty.

Function

Roughly half of the wearer's own body weight is what a single unit adds. The effect is deliberately punishing: whoever wears them moves slower and tires faster.

U.A.'s teachers put them on for the First Term Final Exam, handicapping themselves so their students had a fighting chance in the matchups.
