Is the Large Family Tote big enough for a diaper bag?

Yes. It is one of Vera Bradley's largest totes and holds diapers, wipes, bottles, a change of clothes and snacks with room to spare. The open top makes grabbing items quick.

Does it have a zipper closure?

No. It closes with a drawstring at the top, which cinches the opening but does not seal it like a zip. Keep valuables in an inner pouch.

Vera Bradley quilted cotton is machine washable on cold and should be air dried. Wash it alone or with like colors, and expect some softening over time.

How does it compare with a canvas or leather tote?

It is lighter and more packable than leather or heavy canvas, and it folds flat. In return it has less structure, fewer pockets and a softer, less protective body.

Does it fit under an airplane seat?

The soft body lets it compress, so it generally slides under a seat when not overstuffed. Check your airline's personal-item limits before relying on it as your only carry-on.
