They also have plastic tube ducts for greenhouses, about 24 inches in diameter with holes along the length. Bright sunlight would make them a yearly replacement item.
Using anything flexible on a return would be tricky.--NBC

This product is i believe called duct sock ,i personally think its a cheap product for cheapstakes this same guy wanted us to look into all plastic duct which he believes will be cheaper ,No one carries it or stocks it and it all would have to be pre ordered and delivered by flat rate trucking.The duct sock system requires the use of a alot of static to blow up and i really don t think say a standard 10 or 15 ton roof tops blower would be up to the job .Even though this company will give you design help i think it has it s place some where but not in a production ,r and d amd manafacturing facility peace and good luck clammy
