Big Dog Carrier & Backpacking Pack
Built for adventure, reimagined for comfort—the Kolossus is the ultimate big‑dog backpack carrier that now doubles as a full‑size backpacking pack. Completely redesigned in both appearance and engineering, it delivers unparalleled versatility, durability, and support for you and your dog.
Designed for medium to large dogs (20–80 lbs / 9–36 kg), the Kolossus features adjustable shoulder and torso sizing to ensure an ergonomic fit for a wide range of body types—because comfort and balance should never be one‑size‑fits‑all. When your four‑legged friend isn’t along for the ride, the pack easily converts into a technical backpack with 50–60 liters of storage capacity, perfect for hiking, biking, or travel.
Features:
- Dual‑function design: dog carrier and high‑capacity backpack
- Adjustable, ergonomic fit for optimal weight distribution
- Reinforced construction for lasting durability
- Ample ventilation for pet comfort
- Converts quickly for gear storage (up to 60 L)
Safety & Design:
Every K9 Sport Sack® carrier is developed with input from veterinarians, certified dog trainers, and outdoor gear engineers, ensuring each pack meets the highest standards of ergonomics, safety, and strength—for adventures you can both enjoy with confidence.
