The easy maintenance double envelope allows the inner chamber to be easily removed from the outer envelope for cleaning and examination. It consists of a welded non-porous tasteless PVC water chamber (inner bladder) inside a tough nylon envelope for complete water tightness and resistance to tears and abrasions. Flexible enough to adapt shape during heavy pitching but rigid enough not to burst under pressure. |
