Crawl Space Suit

This is a suit that has an inbuilt thermal regulator to keep the occupant cool even though they are in a 50 degree C roof cavity. Tough material so catching it on beams and nails and whatever doesn’t tear it (not like those flimsy ones you can buy online right now). The idea is that this is almost like an exoskeleton for these guys. In built headphones and phone pocket, ventilator etc. It would be expensive as, but the point is that you can be in and on roofs for longer, meaning businesses can potentially earn more.
