These bags are simple and easy to manage. Fold it up and put it in your tote for those unexpected purchases when you're out and about. They come in an array of colors and are cheap too. You can but 6 bags and 6 pouches (choose the colors of each) for only $38! (via Baggubag)

Reusable shopping bag in fun colors that folds into a 5x5 square and fits in your purse.

stylish. functional. green.

Use the Baggu to reduce the use of plastic bags which are cluttering up the environment! It's easy to make, and even easier to tote with you, since it folds into its own pouch.

It's lightweight, collapsible, reasonably-priced.

My current favorite reusable bags -- like so many of the others, they're strong and hold so much more than a standard plastic shopping bag. These are the ones I don't forget to use -- folded, the Baggu is a flat 5"x5" square. Some of the other compact bags are a little bulky, but I stash these practically everywhere. They come in a wide variety of gorgeous colors, and I really like the long straps that can be carried on the shoulder or in the hand. Almost perfect -- if the carrying pouch was attached, I'd be a happy camper, but that's a minor quibble. I like these so much I bought extras to hand out to friends ... and I've used them as somewhat unconventional gift bags.

Simply way more practical than plastic. Foldable, rip-proof nylon with more than twice the capacity of their plastic brothers.

Nice colors too...
