Looks a bit like a baseball cap but contains a CE EN 1385 Water helmet inside. There's enough overhang of the helmet to cover the tops of your ears.

Black with a white logo on the front. Adjustment is through a snap cap style plastic strap at the back and the chin straps. My head is a long narrow 59cm and it fits me quite well.

Getting rid of it because I don't use it. It's just taking up space in the house. My Gath helmet is comfortable enough and works well with a variety of surf caps and wetsuit hoods. It's just easier to use the Gath all the time rather than choose different helmets for different weather.
