ONETIGRIS MAMMOTH Dog Backpack for Large Dogs, Black, 3L Tactical Hiking Pack

The ONETIGRIS MAMMOTH is a dog backpack for carrying essentials on hikes, walks, training sessions, and runs, with 1000D nylon construction and a 3L pouch.

• Breathable mesh lining — adds airflow against your dog on longer outings.
• Hidden zippers — help keep dog hair from catching and make the pack less likely to unzip during use.
• Adjustable hook-and-loop belly strap with UTX-Duraflex buckles — helps the pack stay in place around your dog.
• Large size fits a 21–31.5 in (53.34–80.01 cm) neck and 29–36 in (73.66–91.44 cm) chest — use these measurements to assess fit.
• Reinforced grab handle with a UTX-Duraflex leash clip — gives you a handle and a leash attachment point on the pack.

On an outing, a dog can carry some of its own water, food, treats, and toys. The MAMMOTH combines pack storage with an adjustable harness-style fit for hiking, walking, training, and running. Its features are designed for practical use while you and your dog are on the move.
