Re-Pac Bags (www.re-pacbags.com) are reusable food bags, which is a good thing because saving on plastic bags is good for both your wallet and the environment. They're leak-proof, dishwasher safe, and are plastic-free ' all good stuff. But I'm not here to talk lunch. These bags have another use which is of interest to gamers. Since they're link-resistant, they're also good at keeping water out. They're the perfect size for a DS, 3DS, or PSP, giving your portable some nice protection from water. Toss it in your backpack and even if you get caught in the rain at least your game system will be safe. And the YKK zippers will also help hold in your games, stylus, and any other loose accessories in. The bags come in a variety of colors and for a third or less of the cost of your typical case made for game systems, and they're not even water-resistant. So if you're looking for an inexpensive way to protect your portable game system, check them out before you spend too much money on a game case.
