Dog Carrier Backpack Kolossus Green : Heavy-Duty Expedition Dog Carrier
The Kolossus in forest green is the ultimate gear for pet owners who tackle the most demanding trails. As the largest and most technically advanced dog backpack on the market, it has been engineered for superior performance and safety. This model allows you to bring your medium to large-sized dog on adventures that were previously impossible, providing a reliable transport solution for pets weighing up to 36 kg.
Technical Support for Serious Adventures
Carrying a larger dog requires more than just a bag; it requires a sophisticated support system. The green Kolossus features an internal frame and advanced weight-distribution straps that shift the load from the shoulders to the wearer's hips. The pet sits securely with dedicated lumbar support and an internal padded lining, while the owner benefits from a thick, padded back panel designed for maximum airflow. This ensures that even at maximum capacity, the experience remains manageable and safe during long-distance treks.
Dual-Purpose Versatility: 60L Gear Pack
What sets the Kolossus apart is its ability to transition from a premium pet carrier to a fully functional 60-liter technical backpack. When your dog is not being carried, the bag offers massive storage for outdoor gear, making it a versatile investment for any hiker. It includes a removable hip belt with integrated waste bag dispensers and accessible storage pockets. Side ventilation zippers and a detachable sunshade for the dog ensure complete climate control, regardless of the weather conditions.
Built for the Elements
Constructed from heavy-duty 300D Ripstop Oxford polyester, the Kolossus is built to withstand rough terrain and frequent use. The interchangeable storage compartment doubles as the dog's back support and features a dedicated Hydro-port for hydration bladders. Whether you are navigating public transport, cycling through the city, or climbing mountain paths, the Kolossus in professional green is the most robust companion for you and your dog.
