Best Use: WhitetailProximity combines industry-leading technologies to ensure you remain undetected during close-encounter situations and to keep you warm in cold-weather conditions. Using proprietary technology, the ultra-quiet Proximity Series combines a low-sheen brushed fabric with a windproof SynthaCell® foam coating for increased protection and warmth retention. Developed from the ground up, Proximity is engineered with purpose-driven features for stand hunting in cold conditions. Features include a safety harness port, hand-warmer holders, and dual chest pockets with rangefinder lanyard attachment points. Leveraging 3DeFX+® insulation, the Proximity Vest locks in heat around core for ultimate temperature regulation. Its outer-layer fit comfortably layers over a base-layer, insulated mid-layer, and a treestand safety harness.
