You can take the sweater off when you’re not sleeping, but it has to be on at night no matter the temperature.
I think I would demand like 200k, just for the discomfort from the scratchiness. I already sleep with a winter blanket all year round so I wouldn’t mind how warm it would get.
200k per year, maybe. I have a heavy wool sweater like something a North Sea sailor in the 1800s would wear, I can’t handle it without a thick long sleeved shirt underneath because of how rough and itchy it is. It’s also incredibly warm. Sleeping in that thing would be like having a full time job every night.
