But in a more practical note, the one-piece Tyvek suit like he's wearing is quick to put on and also keeps the fibers from getting in your clothes. Once they get in your shirt, it gets washed and now they are ready to get into everything else you throw in the laundry.
The gloves might look like overkill but if you get the ones from the pharmacy in the right size for your hand you can work very easily in them, even picking up those annoying little screws that fall on the drywall without taking them off again.
I'd use a paper mask and safety glasses rather than that full-face thing that makes him look a lot like a bug.
