This Avento official referee’s whistle without ball has no moving parts that can freeze or get stuck due to water. The whistle can also be used during rainy weather thanks to the special 3-chamber structure. The tone of the whistle is constant and loud, so it can be heard clearly by all players on the pitch. The whistle comes with a neck cord and is easy to clean.
