We are in Cornwall at the moment and the weather is terrible. We got a free Kampa 5 pole windbreak when we bought our air awning. Fabric material with a clear plastice strip to see through. Metal along the top and plates to push the steel poles through on ground. Metal angled poles for supports. We have also used pegs and yellow string ties. Holding up well in really windy conditions. One problem is yet are very expensive and don't think we would buy if we hadn't got free.
We bought 2 Vanguard windbreaks 5 years ago. They have thin nylon sheeting and thin metal poles which have elastic running through so that they pull apart and fold down small. We have used them on nearly all our holidays, 3 weeks is the longest we go for, and they are still going strong and keep the wind off brilliantly. They stand roughly 4ft high.
My vote is for our 7 pole Quest windbreak from Go Outdoors.
We've got the green stripey one but it come also in blue stripey. The poles are metal tipped at the sharp end and ferruled at the hammering end.
We did manage to snap one pole a few years ago, but replacements are only a few quid.
Advantages for me are, in addition to being sturdy and tall and long, they are hammered into the ground (I use a 2lb rubber mallet, no hammers please) which means that one isn't tripping over guys all the time, especially when camping in a tent or with a porch awning that also have guys to avoid.
Around £50 for the long version. Had our for many years.
