About Kolossus

Big dog, big pack, fewer compromises. The Kolossus is built for carrying medium to large dogs and converts into a backpacking pack with up to 60 liters of gear space when your passenger is walking.
Designed for serious outdoor or urban use, Kolossus combines a large upright carrier format with adjustable shoulder and torso sizing for the wearer. Available in Large through XX-Large, it accommodates dog back lengths from 20 to 29 inches and gives larger-dog households a purpose-built alternative to trying to make a small carrier do an obviously ridiculous job.
No maximum dog weight is provided in the current product information, so fit should be based on the listed back length plus your dog’s body proportions and the wearer’s ability to safely lift and carry the total load.

 

Key Features:
- Designed for medium to large dogs
- Converts from dog carrier to backpacking gear pack
- Up to 60 liters of gear capacity when used without a dog
- Adjustable shoulder and torso sizing for the wearer
- Back-length sizing from 20 to 29 inches
- Built for frequent outdoor and urban use
- Available in Myrtle Green and Black

 

Best For:
- Medium to large dogs who occasionally need to be carried
- Hiking and longer outdoor outings
- Travel where one pack may need to carry either dog or gear
- Larger-dog households that need more carrier volume
- Wearers who want adjustable torso and shoulder fit

 

Sizing:
Large
- Back length: 20 to 22 inches
X-Large
- Back length: 23 to 25 inches
XX-Large
- Back length: 26 to 29 inches

 

How to Measure:
- Have your dog stand naturally on a level surface
- Measure along the back from the collar area at the base of the neck to the base of the tail
- Use actual body measurements rather than breed name alone
- Consider your dog’s width, posture, and overall proportions in addition to back length

 

How to Use:
- Practice loading and unloading at home before taking the pack outdoors
- Use a stable surface and assistance when needed, especially with heavier dogs
- Secure every dog-support strap and buckle before lifting
- Adjust the wearer shoulder and torso settings so the pack sits close to the body
- Recheck balance and strap tension after the pack settles during movement

 

Gear Mode:
- When your dog is not riding, Kolossus converts into a backpacking pack
- Gear capacity is up to 60 liters according to the manufacturer
- Reconfigure the pack fully before loading gear and distribute weight evenly

 

Fit Notes:
- Your dog should remain securely supported without excessive compression or sagging
- The wearer must be physically capable of safely lifting, balancing, and carrying the combined dog and pack weight
- A larger carrier does not automatically make a heavier load appropriate for every wearer
- Reassess fit whenever your dog’s weight or body proportions change

 

Activity Notes:
- Use on controlled terrain where the wearer can maintain stable footing and balance
- Avoid running, cycling, skating, climbing, jumping, or other high-impact or high-fall-risk activities
- Take frequent breaks with larger dogs and monitor both dog and wearer for fatigue, overheating, or discomfort

 

Safety Notes:
- Inspect fabric, seams, structural components, straps, buckles, and adjustment hardware before every use
- Discontinue use if any load-bearing component becomes damaged or unreliable
- Never leave your dog unattended inside the carrier
- Use a second person to assist with loading or unloading whenever the dog’s size makes solo handling unsafe
- This pack should not be treated as a crash-tested vehicle restraint unless specifically certified for that purpose
- Consult your veterinarian before extended carrier use for dogs with breathing, mobility, pain, anxiety, or other medical concerns
