When I finished the part of the qual requiring the airline PFD and needed to remove it, the helmet had to come off first and I mostly deflated the PFD in order to take it off. They're probably designed that way so that they won't come off inadvertently if you don't have the strap on correctly. They'll definitely keep you afloat.
