The best alternative to disposable plastic bags, reusable large snack / sandwich bags are made of the same waterproof fabric as the award-winning Bumkins Superbib. Great for food and fun, snack bags help organize flavors, games, electronics and more. They'll even fit in a baguette! Although the fabric is waterproof, the bags are not completely waterproof due to the zip closure.
