Abstract

L'invention se rapporte à un vêtement conçu pour être porté par des plongeurs et des nageurs, que l'on fabrique en plaçant un moule mâle préfabriqué à l'intérieur d'une cavité de moule préfabriqué, puis en injectant un matériau polymère dans l'espace formé entre le moule mâle et la cavité de moule à l'intérieur de laquelle il est placé. L'invention se rapporte également à un système intégré de vessie à air qui permet de modifier la flottabilité du plongeur ou du nageur.
