Just to fire in my tuppence' worth on windbreaks: We decided to opt for the Kampa 5 panel Windbreak. The grey and black jobby with the bunch of poles.
Quite expensive I might add ! A DISASTER. The worst piece of junk we ever bought. I ended up cutting it up, permanently mounting 2 of the panels at the side of a deck in our back garden and turfing out the remainder. If anyone is thinking or investing: don't. I do like the idea of a windbreak which we like to use when using the Isabella Shadow so I need to but a more suitable one next season. Interested to read recommendations.
