The Water Resistant Turtleshell Speaker

Portable Bluetooth speakers are dime-a-dozen these days, so on-the-go sound systems have to do a little more to stand out. With its rugged, water resistant construction, the Outdoor Tech BIG Turtle Shell does plenty to distinguish itself, giving you a soundtrack in places that other speakers can't.

Besides being dust, water, and shock-proof, the Big Turtle Shell has a full 360-degree sound, projecting clear audio around 30 feet out, and it can play for 16 hours on a single charge. And since the battery is so huge, you can use it to charge your phone or GoPro a full three to six times in a pinch.
