sak, could this be what you are refering to?

Remember to make the mod of folding the bottom up twice. This isn't meant to be a heavy duty kit, but one of minimum storage space. Don't tweak the folds when you open it up, and press folds between fingers to re-flatten after use and before storage. I have boiled water in it, and opened it up and flattened it without leaks.
