The Ruffwear Approach Pack pack is designed to be an everyday pack with excellent performance, fit and functionality. Comfort-fit Web Master Harness frame ensures good structure, stability, and load dispersion. The five-point adjustable fit accommodates dogs of all shapes and sizes. Good for one-hour to three-day hikes. Use to offset your load or for training and exercise. The Approach Pack gives your dog a load to carry and a job to do, generating instant four-legged motivation. The pack's harness should have an all-around snug fit for a stable load and to prevent movement or shifting of the saddlebags. Be sure that each saddlebag has an equal and balanced load.
