Thanks to a proliferation of outdoor-related apps, there's never been a better time to use your smartphone while trekking. The only snag is that the typical smartphone lacks the durability for use in a rugged environment. Just attach the NESTOUT Trekking case to take quick snapshots or check your map using the dedicated holder. The specialized design features MIL-STD conformant drop impact resistance, the buttons make it easy to operate your phone wearing gloves, and there are more features that allow you to upgrade your smartphone into the ultimate trekking tool. Who knew that a smartphone could be an adventure tool.
