The Chest Strap makes it easy to capture immersive video and photos from your chest. It's great for skiing, mountain biking, motocross, paddle sports or any activity where you want a more engaging, lower-than-the-helmet view. You'll capture more of your arms, knees, poles and skis while skiing—and more of your arms and handlebars while biking or riding your motorcycle. Adjustable to fit a wide range of adult sizes.
