It's the Olympus Hera from House of Denial:

I love wearing it, it's much more comfortable than the open options, but it does need to be removed fully every couple of days to be cleaned. There's no way you could get enough access otherwise

It drains out the bottom surprisingly well, without making a mess - gotta sit, obviously, you’ve got no chance standing 😂
