Product description

Dog Backpack Kolossus Black

The long wait for a large pet carrier is finally over! Introduction of the renewed and largest dog backpack on the market. The dog backpack has been completely redesigned in terms of appearance, construction and functionality. The new Kolossus (formerly called Rover 2) is the perfect backpack for large dogs that can now also serve as a separate backpack. It is ideal for carrying medium to large dogs and available in sizes L-XXL. Kolossus technology is at the forefront of safety and comfort for pets and people. Adjustable straps for the shoulder and torso make this backpack more suitable than ever for any body type (as long as you can bear the weight). If you don't have your four-legged friend with you, the backpack can easily be converted into a separate backpack with up to 60 liters of space. Use this backpack for brisk walks and bike rides or for longer journeys by public transport.

    Mijn hond Finley, kruising witte herder en husky, is m’n allerbeste maatje en ik neem hem overal mee naartoe. Klein probleempje: hij weegt 30 kg. Nou dat probleempje is nu opgelost! Hij past precies (en dan bedoel ik ook echt net) in de Rover 2 XXL! Het is echt su-per zwaar om hem te tillen, maar niks wat een paar extra squats iedere avond niet kan oplossen. We moeten er nog mee op pad (daarom nog geen 5 sterren), maar Finley blijft thuis lekker rustig in de rugzak zitten en vindt het prachtig om de wereld van een nieuwe hoogte te zien. Als je een grote hond hebt raad ik zeker aan dat je deze tas neemt! Het is het geld echt waard.
