Tricky one here, surely option A and B can both be true?  I went for A as it sounded more sciency.

Can I have a different colour please?

Yes, but in this case B was also true.

Watch the video. It states the situation quite explicitly, for this fabric.

"A" option is solid, i.e. no holes.

That depends on your digestive system. It can result in either.

I interpret their use of the word solid to not mean a state of matter. Rather an adjective to mean no holes. But I am neither a student of Physics nor English so who knows?

But I did study civil engineering, and we have perforated pipes and solid pipes to choose from for your humble road drainage system.

Can a solid PU membrane really be described as breathable? Wicking yes, but surely breathing implies vapour passthrough? 

I WON SOMETHING!!!
