I'm not sure what its called where you are, but at the Fabricland I worked at we had something called "scuba" and it was really just a poly-spandex (probaly 96%poly 4%spandex) blend that was quite heavy with a one way stretch. I wouldn't get a cotton spandex blend as cotton will relax and stretch out faster than polyester. You're probably better off going to a fabric store and asking one of the people who works there, they'll know their stock best! I also order from spandex world when I can't find what I need locally, they're fairly reliable.
