Chainmail Leggings

Chainmail leggings[a] are an uncommon variant of leggings that cannot be crafted, and are only obtainable through other means such as trading or buried treasure. They are the fourth-highest tier of leggings, having higher armor points and durability than golden and copper leggings.

Zombies, husks, skeletons, strays, and bogged have a small chance to spawn wearing armor, which may include chainmail leggings. There is a 8.5% chance (9.5% with Looting I, 10.5% with Looting II and 11.5% with Looting III) for the mob to drop the leggings they're wearing upon death unless they are spawned from an ominous trial spawner. The dropped leggings are usually badly damaged, and may be enchanted with enchantment levels 5-19.

In Java Edition armorer villagers may give players with the Hero of the Village effect chainmail leggings.
