Made of clear vinyl and ballistic nylon, ZÜCA Utility Pouches are made to fit inside either the Sport or Pro model and let you see exactly what you're carrying.All pouches are designed to be waterproof to keep your liquids form escaping into your ZÜCA bag. Whether it's makeup, art supplies, or the all-important munchies for your latest road trip, you'll have it all right there, ready to put in your ZÜCA bag (or - who are we kidding - on the car seat next to you). Sold individually. Not recommended for packing clothes, though. For that you'll need a set of ZÜCA Standard Packing Pouches. Or you could live dangerously and buy some of each. Hey, just thinkin' outside the box. Er, Bag. Dimensions: 7.5" Wide x 11.25" Long x 2.5" Deep.
