The inflatable ones look fabulous but they aren't cheap....Kempa? We have a very trusty traditional hammer in wooden post windbreak - 7 poles - no more than €15 over 10 years old ....we have another with complex guy ropes and so on - cant be bothered with it!
Just noticed this thread, I got an inflatable wind breaker from ALDI a few months back it was reduced from €200 to €160. Very easy to put up, a few guy ropes with it, also some ground pegs. It has interconnected tubing for inflation. Comes with a hand pump. Took about 5 mins to put up.
