In the 1980s, Mountainsmith built one of the industry's earliest dog packs. After 40 years of continued dog pack innovation, the 2019 K9 Pack introduces the same trusted fit-designed with and approved by a local, Golden, Colorado veterinarian. The 4-point adjustable chest harness, independently adjustable back harness, non-slip buckle system, mesh panels, and perforated EVA foam offer a custom, comfortable fit and added breathability. Now with added water resistance, your dog's gear is protected from unpredictable weather, shallow river crossings, and inevitable mud puddles. The increased space of the pannier compartments and the added zipper accessory pockets also mean more room for the K9 essentials
