HydroFoam Construction: HEYDAY mallard duck decoys utilize HydroFoam construction, the same closed cell EVA resin as Crocs. These duck hunting decoys are lighter, more durable, and quieter than any plastic mallard decoys. HollowCore Body: HEYDAY mallard duck decoys feature a HollowCore body, which reduces weight. The HydroFoam material naturally floats, making these duck hunting decoys lighter than traditional mallard decoys. SmoothMove Dual-Keel: Our mallard duck decoys include a SmoothMove Dual-Keel design. This feature allows duck hunting decoys to glide naturally, unlike single keel mallard decoys that move erratically. Fool 'Em Finish: HEYDAY mallard duck decoys boast a Fool 'Em Finish. The HydroFoam texturing adds realistic detail, enhancing these duck hunting decoys' appearance compared to plastic mallard decoys. Realistic Movement: The Dual-Keel design of HEYDAY mallard duck decoys simulates real duck behavior. This innovation in duck hunting decoys ensures that mallard decoys move naturally in the water.
