One day my latex neck seal tore at just the wrong time and I had to bin a dive. It was at the time when it was pretty much impossible to get a latex seal instantly changed in the field. It was a problem that manufacturers took notice of. In the mid to late noughties a couple of solutions were launched. DUI unveiled their ZipSeals, whilst Waterproof worked in partnership with SI TECH to develop the Neck Tite System.
