Sea Crown

Only seen in a Siebe Gorman catalog where they write the following: " Dry frogman's suit with integral helmet of glass fiber with visor; incorporating breathing connections for use with any type of breathing circuit and suit inflation cylinder".

If you have more info about this interesting helmet, don't hesitate to contact us.


The helmet was only a prototype and was built to work with a rebreather. The helmet did not use a neck dam, but rather was attached to a dry suit neck yoke. It had an oral-nasal mask and a wrap-around polycarbonate face visor. The visor was hinged and could be opened sideways. The white shell was fiberglass.
