Material & Hardware Specifications
Main Material (Printed Polyester Webbing): The core structure of the harness is crafted from high-density polyester webbing. Known for its exceptional tensile strength, abrasion resistance, and dimensional stability, this material ensures the harness can withstand the pull of active dogs while allowing for vibrant, customized pattern prints.

Buckle (ABS Quick-Release Buckle): The primary closure features an engineering-grade ABS quick-release buckle. This material delivers excellent impact resistance and durability, ensuring a secure lock and effortless one-click removal for a hassle-free wear experience.

Adjustment (Adjustable Day Buckle): Designed for a precision fit, the adjustable tri-glide (day) buckle allows for smooth resizing, ensuring the harness snugly conforms to various dog body shapes without chafing or restriction.

Leash Connection (Double D-Ring Design): The dual D-ring configuration provides a heavy-duty, balanced anchor point for the leash. By distributing pulling force evenly across the harness, it enhances security and control during walks, effectively minimizing the risk of hardware failure under sudden tension.

Extra Hardware (Metal O-Ring & Plastic Keeper): Equipped with a versatile metal O-ring—ideal for attaching ID tags or waste bag dispensers—and a functional plastic keeper that neatly secures excess webbing strap for a clean, streamlined look.

Style (Lightweight H-Style Harness): Engineered into a classic H-shape configuration, this lightweight style distributes pulling pressure across the chest and shoulders rather than the neck, protecting the pet's trachea.
