The Surface Book 3 used to be Microsoft’s most powerful laptop. It's been succeeded by the new Surface Laptop Studio. At the time when it was new though, it was groundbreaking. It featured a premium design language and a detachable form factor available in either 13.5-inch or 15-inch sizes. Though we don't suggest buying it anymore due to the older 10th-gen Intel Core processors and older NVIDIA GeForce GTX 1660 Ti Max-Q graphics, you still might mind the detachable form factor better over the laptop factor of the Surface Laptop Studio.

This allows you to easily switch between tablet and clamshell form factor. Plus, thanks to the hardware, it can be used for high-end tasks, like light content creation, and light gaming. So if you want to add some extra protection to your Surface Book 3, here are some of the best case options. Do note that almost all the options below should also fit the 13.5-inch and 15-inch versions of the Surface Book 2.

These are some of the best cases for the Surface Book 3. As mentioned before, some of these will also be compatible with the older Surface Book 2 model. However, it's best to check and confirm before you buy one. We do suggest picking up a specially designed case, though. The UAG Plasma and the iPearl mCover are two of the best. But if you want something cheaper, a basic sleeve will help protect your device when you're on the go, too.
