Best Rugged Surface Go Case
The best rugged Surface Go case available so far is the Pelican 1065CC HardBack Tablet Case.
This is a case that closes up to protect your Surface Go from extreme conditions. It is water tight, crushproof and dustproof. The only catch is that you cannot use the Surface Go when it is in this case.
The Pelican 1065CC is designed to keep tablets like the Surface Go safe in transport and when not in use at a rough location.
Interior dimensions of the case mean this will fit the Surface Go easily and should fit the Surface Go with the Type Cover as well.
