Lycra full-body suit, zipped front and with belt.

I attempted search on the internet, found nothing!
Looking familiar.
Since they wore the same suits. Could be diving lesson, helmet dive (cooler weather).
Then there was a chance they were making adult movie

Very frustrating - seems to be part of a team uniform and excess of material at the wrists confuses me (plus the belt) as to the activity involved.
Good point though - location appears to be inside ship.

My guess it is neoprene for diving. The belt is a type they used to use to hold the weights to make you zero buoyant.

..... I think I actually see one of those weights at his left hip - and the strength required in a nylon belt would accordingly be explained too.

Most definitely a diving suit.
