Ateco Wunderbag 14-inch Reusable Pastry Bag

The Wunderbag is the bag Ateco designs for professional bakers. It is made from heavy cotton felt with a polyurethane coating on the inside, a much thicker construction than Ateco’s nylon and polyester bags.

Why Cotton Felt

The thick cotton puts a layer of insulation between your hand and the filling. That keeps warm ganache and choux paste from heating your palm. The felt also gives a firmer grip than smooth plastic, and the coated cotton cleans up more easily than a canvas bag. Ateco notes that the bag softens with use, so a new Wunderbag feels stiffer than it will after a few washes.

The 14-inch Size

Fourteen inches is a manageable length for cupcakes, rosettes and finishing work on plated desserts, where a large bag would be unwieldy.

The Wunderbag also comes in 18-inch, 24-inch and 28-inch sizes. For a lighter, less expensive bag of the same length, see the Ateco Flex 14-inch. The pastry bag buying guide covers coated cotton alongside the other reusable materials.
