Task: Question Generation
Input (English): Context: The ability to recycle a shell became a holy grail for us . We knew we would need to use 100 % polyester for the entire composite fabric , and , to make that workable , we would have to develop with our suppliers a more breathable barrier . We 're proud to say that our fully recyclable polyester fabrics ( check out the Eco Rain Shell Jacket ) perform just as well as non - recyclable fabrics .
Output (English): Why might we emphasize having a recyclable shell ?
