Product title: Spiffy Dog Grey Trout Collar - Large
Product description: The Spiffy Dog Air Collar is the newest innovation in dog collar technology. This collar is constructed of soft Nylon Aerospacer. Aerospacer is a material that is constructed with small air chambers within the outside layers. These air chambers along with hydrofil nylon wick away water allowing the collar to breathe and dry faster, resisting odors and mildew. The Air Collar is great for dogs with short hair because it is soft and does not rub on the dogs skin like some leather and webbing collars. This Collar is also great for dogs with allergies to some collars. The Air Collar is super strong and the quick release buckle is made especially for dogs and will not break. Reflective Soft, Light weight and Comfortable Non-Chaffing Quick Drying Resists odors and mildew Super strong Adjustable sizes Available in two sizes: Medium adjusts from 16" to 20", 1" width Large adjusts from 20" to 26", 1" width
