Ideally, we’re not always hiking, running, climbing, or crawling with a fully loaded rucksack.
During intense activity, your body can lose more than 1L of water per hour.
Carrying water bottles isn’t ideal—they add weight, shift around, and can feel bulky during movement.
That’s why we created the Endurance Kit.
The Endurance Kit combines the Pull Harness and Plate Pouch into a lightweight vest for hikes, runs, climbs, and crawls during OCR training.
-
When attached together, they form the Endurance Kit.
-
When used separately, each piece becomes a standalone training tool:
-
Pull Harness – Pull up to 1,000 lbs or perform sled runs with the SandRuck and Drag Bag
-
Plate Pouch – Load barbell plates to transform it into a 30 lb dumbbell or kettlebell
-
⚠️ Note: When attached to the Pull Harness, the Plate Pouch is not recommended for loads greater than 10 lbs.

CAREFULLY CRAFTED
Built with intent for athletes, military and first responders.
