Yeah no. Those are tyvek suits that are used for pesticide application. To complete the outfit they need some nitrile gloves and a fitted respirator.

For pollen isolation there a whole bunch of different techniques depending on the species. None of them involve getting dressed in one of those uncomfortable monstrosities. I used gel caps when I bred cantaloupes and honeydews (the types used for medications). Slap one over the top of a pollinated flower and it keeps the pollinators away.
