Designed to be durable, Outdoor Tech’s Turtle Shell Speaker is up for anything. Containing a water-resistant, dust-proof, and shock-proof shell, there isn’t much that this speaker won’t be able to handle. But beyond its toughness, the Turtle Shell will lend its Bluetooth audio capabilities for up to 9 hours off a single charge, allowing you to enjoy all your favorite jams from any smartphone, tablet, or laptop. Built-in call and speakerphone features help to avoid interruptions whether you’re out in the wilderness, or just inside winding down. Buy one in any of the 7 colors HERE.
