Formerly known as the Rover 2. The Kolossus is the same as the Rover 2 in everything but name.
TOP TIP - If your dog is near the top of a sizing bracket, or looking for a roomier fit, we would highly recommend sizing up.
PLEASE MEASURE YOUR PET BEFORE PURCHASE TO ENSURE YOU ORDER THE CORRECT SIZE

Completely redesigned in appearance, construction, and functionality, the Rover 2 is THE big dog backpack carrier that now doubles as a backpacking pack. It is ideal for carrying medium to large dogs and available in sizes L-XXL. Rover 2 technology is top of the line in pet/human safety and comfort. Adjustable shoulder/torso sizing makes this backpack more suitable than ever for all body types (as long as you can withstand the weight). When you're not carrying your 4-legged friend, the backpack easily converts to carry your gear with up to 60 litres of space. Use this backpack for strenuous hikes, bike rides, and public transit.

How long can my pup stay in the Sport Sack?
The time limit is determined by your climate and activity, however on average we recommend that the dog not stay in the bag for any more than 45 minutes at a time. For hotter climates this number should decrease proportionally.
