Description & Size guide

K9 Active is committed to making it easier to get out and about with your canine companion, and that’s why we recommend the Trail Runner System by Ruffwear for anyone who wants to enjoy exercising with their four legged friend.

Specially made for fitness aficionadas who love to hit the trails and let off some steam, it’s perfectly suited to running together, offering you a simple and straightforward way to stay connected when you’re spending quality time in each other’s company.

The ideal piece of equipment for park run events and other instances when you need to keep your dog on its lead but prefer to have your hands free, the system includes a belt, ridgeline leash, and water bottle, with the stretch mesh pocket offering instant access to essentials, and a perfect place to keep your collapsible bowl or pick-up bags. It even incorporates a weather-resistant pouch with a headphone hole, so that you can safely store your mobile phone but still listen to music on the go.   

The Trail Runner System has not been made with practicality alone in mind, but your comfort too, hence its clever bounce-free and load-dispersing design. Made to sit neatly on your waist, you’ll barely even notice that you’re wearing it.

Suitable for use both during the day and when visibility is reduced, the system includes an in-built Light Loop, which can be used alongside Ruffwear’s Beacon to make sure that you and your canine companion are easy to spot even in the dark.  

Offering the perfect set-up for those who like to combine exercising with some quality outdoor time together, the Trail Runner System is ideally suited to everyday running, and is sure to keep you covered for every eventuality.

For those more serious about competing in canicross or tougher trials, Ruffwear also offers the Omnijore System as a slightly more hard-core alternative.
