Hybrid Weight Vest MK2 Kit - Battle Bunker

Hybrid Vest MK2 - Built for Real-World Strength

Built for real-world strength and endurance, the Battle Bunker Hybrid Vest MK2 isn’t just a weighted vest, it’s a piece of performance gear engineered to move with you, not against you. Designed and assembled in the USA from 1000D military-grade Cordura, this 20 lb vest combines tactical durability and elite athletic performance in one sleek, low-profile design.

The Hybrid Vest MK2 lays flat against your torso and conforms naturally to your body, giving you unmatched stability during runs, jumps, push-ups, and functional training. Whether you’re hitting Murph, grinding through hybrid conditioning, or tackling outdoor endurance workouts, this vest stays locked in with no bounce and no bulk.

Unmatched Fit & Function

4" Elastic Cummerbund with Dual Velcro Closure delivers a secure, custom fit that hugs your core without restricting movement.
Quick-Release Shoulder Straps with thumb loops allow fast on/off transitions while maintaining consistent shoulder comfort.
Fully Adjustable Shoulders fit athletes from 5'0" to 6'5", accommodating a wide range of builds with ease.

Engineered for Performance

Cooling Spacer Mesh Liner keeps airflow moving and sweat under control even in long, high-heat sessions.
MOLLE/PALS Webbing System allows easy attachment of accessories, training tools, or tactical gear.
Three Stainless Steel D-Rings and Two Nylon Loops give you anchor points for resistance bands, sleds, or even a dog leash for dynamic training.
Front and Rear Velcro Panels let you customize your look with patches, team logos, or name tags.

Built to Endure

Every Hybrid Vest MK2 is reinforced with 20 pounds of precision-balanced steel shot, encased for safety and longevity. This isn’t a foam-filled gimmick, it’s real, rugged weight designed to withstand years of hard training.

From the stitching to the steel, every detail was tested and refined by the Battle Bunker team to meet one standard: unbreakable performance.
