If you love the idea of being that cool mom who brings her own canvas tote to the convenience store – but know that you never in a million years will be able to cram a canvas tote in your already overstuffed diaper bag – have we got a solution for you.

The Flip and Tumble 24-7 bag was designed by two Stanford design program grad students and it’s a totally smart and stylish way to get a little greener. Basically it’s this sturdy but crazy lightweight, sweet little tote that scrunches up and tucks inside its own inside pocket. It ends up about the size of a baseball and weighs pretty much nothing.

Price? Just 12 bucks.

So basically, you have no more excuse not to say no to the plastic bag with your next impulse Us Weekly magazine purchase. I mean, um, The Economist.
