iPhone 5 neoprene sleeves?

I pre-ordered a grovemade.com case and of course my new iPhone is out in the open just waiting for me to drop it until early Oct. I have a case logic laptop sleeve that I really like and am looking into something similar for the iPhone in the meantime, especially since most are under $10 on amazon. Does anyone know if the Nintendo DS is a close size comparison to the 5?

I've found this so far but don't own a DS to know if it would fit properly.

I figure I could use it afterwards since it would work for me when traveling on the motorcycle to keep it from getting beat up in my tank bag.

Let me know if this idea would work. Thanks!

Did some research for myself and got this:

Nintendo DS dimensions: Physical dimensions:
148.7 mm × 84.7 mm × 28.9 mm (5.85 in. × 3.33 in. × 1.13 in.)

iPhone 5 dimensions:
Height: 4.87 inches (123.8 mm)
Width: 2.31 inches (58.6 mm)
Depth: 0.30 inch (7.6 mm)
Weight: 3.95 ounces (112 grams)


So in short, yes...
