Now this is an interesting product. I haven't used it myself, but saw it on store shelves at Simple Pleasures recently. The Vapur website calls it the "Anti-bottle, the first flexible water bottle designed to fit in your purse, backpack or briefcase". The website also states it is dishwasher safe and BPA free.
