Core Product Advantages All-Round Breathable Mesh Padded Comfort Lining The whole inner surface is covered with thick elastic 3D air mesh padding, soft and sweat-wicking. It evenly disperses pulling pressure to avoid neck chafing, red marks and strain even during long-time training or all-day outdoor activity. The hollow mesh structure keeps pets cool in hot summer without stuffiness. Built-In Emergency Control Handle Unique integrated top loop handle allows instant grabbing to restrain excited, rushing or dangerous dogs during training, crossing roads or crowded public areas. The handle is reinforced with cross stitching to bear strong pulling force without tearing, ideal for K9 trainers and guard dog owners. Reflective Edge Stripe for Night Safety High-visibility reflective piping runs along both sides of the collar, reflecting light from street lamps and vehicle headlights at night to greatly improve pet visibility and avoid traffic risks for evening walks. Multiple solid and camouflage colorways are available for customization. Ultra-Sturdy Heavy-Duty Hardware & Webbing Extra wide high-density military-grade nylon webbing with full cross reinforcement stitching, anti-tear and wear-resistant. Equipped with heavy-duty zinc alloy metal quick-release buckle, it locks tightly and withstands violent surges from powerful large dogs.
