Designed for active photographers, the CCS G3 Harness-1 from Cotton Carrier helps evenly distribute the weight of a DSLR or mirrorless camera with a long lens. This arrangement keeps your camera at the ready for making the most of spontaneous photographic opportunities. It keeps your hands free, protects equipment from grab-and-go theft, and reduces unwanted camera movement. Photographers will appreciate the one-size-fits-all approach with adjustable shoulder straps and a quick release waist belt.
Two stash pockets store memory cards or batteries and the large exterior pocket stores accessories. The CCS G3 Harness is constructed from Kodra synthetic canvas and anodized aluminum. It has a Twist & Lock camera mounting system and a vented back panel. Included with your harness are a hub with rubber washer, a camera hub mounting bolt and tether strap, an Allen key, and a rain cover.
Option 2: 10-Degree Angled Hub for a DSLR with a long lens.
Option 3: Universal Tripod Adapter Plate. This plate is compatible with most tripod heads on the market. It is cut to fit directly into any Arca-Swiss style head, and designed with enough adjustment holes to slide back and forth on the bottom of your camera to leave the battery door accessible.
