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 :D

:confused: 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.

It is a front zip wet suit for scuba diving. Finally someone got smart and put the zipper in reach and not on the backbone where the heavy tank grinds it into your spine. Much easier to get into too. It comes in various thickness of neoprene depending on the temp of water you are diving. I also have a Lycra one that is a full body running tight. (more often seen for woman but really a unisex garment)
