Using your Ridgeline Kahu Binocular Harness is a breeze. First, adjust the harness to fit your body comfortably. You can use the adjustable tethers to secure your binoculars in place. The magnetic closure allows for quick one - handed access when you spot something interesting. Keep your phone in the large zipped pocket for easy reach. You can also attach a range finder or ammo pouches using the Molle system. When it rains, simply put on the water - resistant rain cover to protect your binoculars. As for maintenance, clean the harness with a mild soap and water solution. Avoid using harsh chemicals as they might damage the 100% recycled 300d ripstop polyester material. Let it air dry thoroughly before storing. Make sure to check the internal shims regularly and adjust them if the fit of your binoculars changes.
