Just like when you asked about ink flex, it sounds like it could be another Ironall name. You can try to confirm that on the Hyatt website. That's how I confirmed the Ink Flex name for you. When they say it is soft or stretchy, or that is it better than
JPSS, it is usually someone trying to sell Ironall light. Usually, not always. Try to confirm on Hyatt if this supplier is listed on their site as a distributor. That worked last time.
It may be something else, but first make sure it's not an Ironall. Most times, not all, it is. Good luck.
