Unleash Adventure with the Mountainsmith 2019 K9 Pack! Hey, fellow dog lover! The 1980s saw Mountainsmith pioneering dog packs, and now, with over four decades under our belt, we're still leading the pack (pun intended)! Introducing the latest in canine gear: the 2019 K9 Pack. Made with love and insights from a vet right here in Golden, Colorado, this pack is more than just an accessory - it's an adventure staple for your furry friend. Imagine a pack that thinks about your dog's comfort as much as you do! With its 4-point adjustable chest harness, this pack promises a snug fit. No more slipping and sliding - our unique buckle system, combined with an independently adjustable back harness, ensures your dog's pack stays put, even on those wild chases after squirrels. But wait, there's more! We understand that dogs will be dogs - from those unexpected summer showers to those irresistible muddy puddles. That's why we've ramped up the water resistance, ensuring your pet's treats, toys, and gear stay dry, come what may. Mesh panels coupled with perforated EVA foam ensure breathability, meaning more comfort on those long hikes. Plus, with increased pannier space and added zipper pockets, there's plenty of room for all the doggy essentials. So, gear up for an exciting hiking season, let your pooch carry their share of the load, and explore the wild together.
