The present invention relates to a swimsuit comprising swimming trunks, a compressed gas cylinder with a user-operated valve, and one or more inflatable bladders attached to the swimming trunks. A pusher is movable between a retracted position in the body and a forward position in a selvage to expel from the selvage the nose of the lock and release the latter. The etch stop layer may also serve as a barrier layer, buffer layer, andor template layer. The conductive adhesive may be at least partially soluble in electrode casting solvent.
