True to Nathan, this waistpack has storage for any essentials or doggy supplies you may need and allows you to run without having to hold on to your dog’s leash. Simply clip the leash to the guideline on the pack and the leash will slide side-to-side as your dog changes sides. The leash comes with handles at both ends giving you options for controlling your pup and has a feedback system that pulls back on your dog if they start to pull. • Storage for running/doggy essentials • 360 degrees of reflectivity • Side-to-side guide line • Feedback leash • One size fits most belt
