Introduction:The “st-27” is fully adjustable to fit all sizes. Makes it easy to capture immerse video and photo footage from, well…your chest. Perfect for skiing, mountain biking, motocross, paddle sports, or any activity where you want to get a “lower than the helmet” view of the action. See more of your arms, knees poles, and skis while skiing…or your arms and handlebars while biking or riding your motorcycle. Recommended as a more immersive way to film than on the helmet.Features:Perfect fit for gopro wearable cameras Harness adjustable size: 60-100cm Main material: abs plastic color: blackChest mount harness is fully compatible with all gopro sport cameras.Chest mount harness work excellent with following devices:Gopro heroGopro hero 2Gopro hero 3Gopro hero 3 / black editionGopro hero 3 / silver editionGopro hero 3 / white editionGopro hero 2 / outdoor editionGopro hero 2 / motorsports editionGopro hero 2 / surf editionGopro hero / motorsportsGopro hero / surfGopro / nakedPackage includes:1 x chest mount harness1 x vertical surface j-hook buckle
