I've been in Asia for the past couple of weeks and experienced the full force of Typhoon Hugapit as it swept across Hong Kong. Massive wind gusts gave me a chance to test the security of the full cap. I've always maintained that full caps are more secure than toppers due partly to the much greater surface contact area and the fact they sort of mould themselves around your head.

The SFS/French unit was only taped down with five pieces of Walkers contour tape - one down each temple/sideburn, one across the front and two around the back. Despite 120km/hr winds it never looked like shifting or coming unstuck, though the hair itself naturally got blown around a bit. The confidence these things inspire is amazing.
