Snow Cloakin Pokémon Polished Crystal

Snow Cloak is an ability that increases the Pokémon's evasion by 20% during hail weather conditions. This means that when hail is active on the battlefield, the Pokémon with Snow Cloak will be harder to hit with attacks, giving it a defensive advantage. Snow Cloak is particularly useful for Ice-type Pokémon or those that already benefit from hail, as it enhances their survivability in such weather.
