Arc/run through/open ended field shelters?

Anyone used one of the above type shelters? I am contemplating building a couple in my field, but my only worries are that it may become a wind tunnel.

Polytunnel works for mine!

I have a protech one although I use it with one end blocked to hurdle height for sheep or fully closed for horses.

Any pictures of your polytunnel? Have you cladded it at all?

I was thinking today as I drove past an allotment about making a roof of a shelter with 'blue pipe' but didn;t know if it would be strong enough.
