The Athlon Optics Binocular Harness is the most functional, versatile binocular system in the market. It holds your binoculars tight to your chest, and is designed for quite, one-handed use. Whether carrying a rifle or bow in one hand, the magnetic opening can easily be opened with your free hand and use your binoculars for the moment that counts. With the multiple shoulder and neck adjustments, this allows the binocular harness to hold close to your chest and prevent sag and bounce when crawling or running. The harness allows for a full range of motion while the binoculars are in use.
