There’s a new GoPro in town, and it’s smaller and lighter than ever before. The HERO4 Session offers ultra high-resolution video, astonishing slow-mo playback, more mounting options than previous versions, an easy-adjust ball-joint buckle so you can quickly switch your angle on the go, and one simple button to get it going. Better pick up some extra storage, too—we predict heaps of first-class footage in your future.
