Duck-feather shuttlecock with synthetic cork and high-density foam head — engineered for lightweight flight, durable play, and reliable performance during training, school sport and travel. Key benefits Practical mobility: Duck-feather structure makes the shuttlecock especially lightweight and easy to pack, saving space in bags for training camps, school sport lessons or travel kits. Durable material core: High-quality synthetic cork gives robust impact resistance while preserving precise play characteristics; the tough surface helps maintain consistent behavior throughout a full match. Long-lasting feather construction: Selected duck feathers with a straight, dense and stable feather structure deliver sustained flight performance even under intensive, frequent use. Stable flight and rebound: A high-density foam head provides optimal restitution for a predictable, steady flight path and repeatable feel on every hit. How this product solves common problems Reduces replacements: Durable cork and reinforced feather structure cut down on shuttles that break or change behavior after a few rallies. Keeps performance consistent: Resistant surface and foam head preserve speed, trajectory and rebound so players can focus on technique rather than adjusting to variable shuttles. Simplifies transport and storage: Lightweight, compact packing makes it practical to carry multiple shuttles for long training sessions or trips. Suitable applications Training camps and club practice sessions where many repeated hits and long-duration use demand durable shuttles. School sports and physical education classes that require easy-to-store, reliable equipment for groups of players. Travel sets for players who need compact, lightweight shuttles that still deliver consistent flight and feel away from home. Materials and performance highlights Feather: Selected duck feathers, straight and dense for stable aerodynamic properties. Cork: High-quality synthetic cork for durability and consistent impact response. Head: High-density foam head for reliable rebound and steady flight trajectory. This shuttlecock is designed to offer reliable, repeatable performance for practice and recreational play while remaining easy to transport and resistant to wear from frequent use.
