The Ruffwear Hoopie Collar in solid colors is a no-nonsense universal flat webbing collar-the name derives from a term used by outdoor enthusiasts for strong, flat nylon tubular webbing or a hoopie. The collars clean, classic styling takes the standard a notch further with upgraded hardware and 4000 lb. tensile strength flat tubular webbing. ID tags attach separately from all other hardware, reducing annoying tag rattle. Try Ruffwears matching Roamer and Flat Out Leashes for the complete set up.
