This BUMBIN harness is like a little tactical vest for your pup! The XL size fits necks roughly 21-31 inches and chests 22-44 inches (measure your dog carefully). It's made from durable nylon and has a breathable mesh lining for comfort. Key features: a NO-PULL front chest D-ring for training, a standard back D-ring for casual walks, reflective strips for night safety, and a whole MOLLE system on the sides and back. That MOLLE webbing lets you attach pouches (like the included bag), patches, or other gear. It adjusts with both buckles and Velcro for a secure fit. The purple camo color is pretty unique. Great for active dogs, training, hiking, or just making your German Shepherd, Husky, or other large breed look like a ready-for-anything adventure buddy. Please note: Sizing can vary slightly; always check the specific size chart for the best fit.
