Kevlar® has long been associated with bulletproof vests, military applications, and aerospace technology. Now creating the Kevlar toughest balls with ultra-durable material is revolutionizing the fitness industry with medicine balls, sandbags, and slam balls that withstand the most rigorous training sessions.
Core Health & Fitness, through its Throwdown® brand, is harnessing the strength of Kevlar® to create the toughest, most durable training equipment on the market.
What is Kevlar®?
Kevlar® is a synthetic fiber invented by Stephanie Kwolek in 1965. Initially developed for lightweight, high-durability tire reinforcement, Kevlar quickly proved to be one of the strongest materials in the world, with a unique molecular structure where it is five times stronger than steel by weight. It has since found applications in body armor, aerospace, fashion, and now, fitness equipment.
Kevlar Properties
- High tensile strength: Kevlar is extremely resistant to stretching and tearing.
- Lightweight properties: Compared to steel, Kevlar is much lighter while providing similar strength.
- Durability: The material withstands wear and tear, making it perfect for high-impact applications.
- Heat and chemical resistance: Kevlar does not melt and is resistant to many chemicals, making it ideal for extreme conditions.
The Story Of Kevlar’s Inventor Who Changed the World: Stephanie Kwolek
Stephanie Kwolek, the pioneering female scientist behind Kevlar, never set out to create one of the world’s strongest materials. Her initial goal was to develop lightweight fibers for industrial use. During her polymer experiments, she discovered a solution that behaved differently from other synthetic fibers. Instead of discarding it, she pursued further testing—leading to the invention of Kevlar, which has saved countless lives in military, law enforcement, and personal safety applications.
Why Core’s Kevlar Products Are The Toughest Balls in the Game
Fitness equipment must endure repeated impact, friction, and environmental stress. Core Health & Fitness, through its Throwdown brand, is introducing Kevlar into medicine balls, slam balls, and sandbags to enhance their longevity and performance.

3. 14” TacTec Kevlar Medicine Ball
This version incorporates high-tensile TacTec™ Kevlar for added strength and grip. It’s the perfect tool for high-intensity functional fitness training and explosive movement exercises.
4. XD Slam Ball
Engineered with a grooved tire tread texture, this Kevlar-reinforced slam ball is built to resist bounce, maximizing energy transfer. It is ideal for:
- Strength training.
- Core stability workouts.
- Cardio and agility training.
5. Keprotec® Kevlar®Sand Disc with Foam Handle
Sand discs are versatile training tools, but traditional designs wear out quickly. This Kevlar-infused model features:
- Foam handles for enhanced grip.
- Steel sand filling for dynamic weight distribution.
- Soft-weight construction to reduce impact and prevent floor damage.
6. Keprotec® Kevlar®bag
This sandbag redefines durability with:
- Ultra-reinforced Kevlar fabric.
- Five nylon handles for various grip positions.
- Pre-filled weight for convenience and balance during workouts.
The Benefits of Kevlar For Fitness Training
The integration of Kevlar with fitness equipment marks a significant leap forward in durability and performance.
1. Ultimate Durability
Kevlar’s fibers are designed to withstand extreme pressure, making them perfect for fitness gear that undergoes intense, repetitive use. Whether it’s slamming a ball against the ground or performing heavy lifts with a sandbag, Kevlar ensures the equipment lasts longer than conventional materials.
2. Low Maintenance
Unlike traditional fitness equipment that deteriorates over time, Kevlar-reinforced products require minimal maintenance. They resist wear, cracking, and fraying, making them a worthwhile investment.
3. Safety Enhancement
With Kevlar’s high-tensile properties, fitness enthusiasts no longer have to worry about medicine balls bursting or sandbags leaking. The reinforced construction guarantees safety even in high-impact exercises.
4. Sustainable Performance
Unlike rubber-based alternatives that degrade with exposure to moisture, heat, and UV rays, Kevlar remains virtually unchanged even after prolonged use, maintaining consistent performance.
