This is a set of 5 shopping/carrying bags packaged in a 4 inch by 8 inch pouch. Each bag folds and rolls up in a space slightly larger than a D size battery. The bags are a thin polyester taffeta material, patterned on one side. They have straps with snaps for securing them after they are rolled up. The bags are about 18.5 inches by 17.5 inches on the flat, and can open up to about 16 inches wide in the center.

The primary purpose of the bags is to replace shopping bags, but they are useful for much more than that.

They are very lightweight and easy to carry. I have only used one bag so far, but it carried two fairly large packages (each a large cookbook in a box) and 25 Christmas cards easily, with room to spare. The handles are wide and do not hurt your hand, even with a heavy load. They do not have a square bottom, however, and fall over easily - so be careful how you set them down.

I was happily surprised at how well made and functional they are. I was also happy to find that they roll up as easily as they unroll, and it is quite easy to roll one up and stash it back in the carrying pouch (which also has snap closures).

The handles are quite large, almost large enough for me to put the bag on my shoulder over a winter coat (but not quite). They are 3 inches wide and are cut directly as a piece of the side material.

To fold a bag up again, one folds it in half sideways, folds the handles down against the side of the fabric, then folds the remaining part over in thirds, securing the handles underneath the folds. Then one rolls the bag towards the bottom where the securing bands and snaps are located (like rolling a sleeping bag or toothpaste tube). Much easier than it sounds, believe me, and instructions are included on a separate page as well as being printed on the bag.

A great idea well implemented. I really would like to give them 4.5 stars, as my only concerns are that the hole in the handles be just slightly larger and I don't know how well they will hold up under heavy use. If they last well, I might just have to up the rating to 5 stars. Good job, Envirosax!
