This are two products that will protect your Nintendo DSi XL or DSi and after I did my research I found them to be probably the best on the market for this gaming console. This are the CM4 external housing and the Pelican 1040 case. I will give you in the shortest way I can the information on where to get this items and why you should get them.
Step 1: CM4 Housing

Step 2: Pelican 1040 Case
Pelican makes cases for almost everything. I got the specific measurements of the Nintendo DSi XL and found that this case is perfect for it. Strong, water tight, pressure valve integrated and a good interior protective material.

Step 3: Last Words...
There are few colors to choose and at the same type this specific case comes with a clear lid of solid like this one in the instructable. I choose this one because first it has an internal protective foam and second nobody can see what is inside. I travel a lot with the military and I don't want others looking at my personal things. The clear lid if I'm not wrong, doesn't have the internal protective material.
I hope somebody can take advantage of this instructable for good doesn't matter if you don't actually get this items but at least consider the advantages of them and improvise, use your brain and get the most out of it. This is one of the reasons i love this site.
