I've got a Ron Thompson too and it holds up fine, it even withstood the winds on Holderness on the 2nd day of the British Open, although the wind piled sand about 3' up the back of it. I've also got an "Instant Bivvy" that I bought from Revels Fishery in Dorset. They knock 'em out for £20 and although it ain't much use in a strong wind, it's got loads more room that a buddy, you can even stretch out and have a kip in it. It's a doddle to erect and collapse too.
