Bone Chiller Cooling Plate

Bone Chiller: A Simple Upgrade That Makes a Big Difference

Anyone who has worn body armor for extended periods knows the challenge: heat buildup, trapped sweat, and discomfort inside a plate carrier. Whether you're training at the range, working long shifts, or wearing armor in hot climates, staying cool and comfortable becomes a serious factor in overall performance.

That’s where the Spartan Armor Systems® Bone Chiller comes in.

Designed to fit inside virtually any plate carrier, the Bone Chiller creates airflow channels between the body and the interior of the carrier. The result is improved ventilation, reduced heat retention, and a noticeably more comfortable experience during extended wear.

It’s a lightweight, low-profile solution that can make a major difference without changing your existing carrier setup.

Why Heat Management Matters in Body Armor

Plate carriers and armor systems are designed to protect vital areas of the body, but that protection also traps body heat. Once heat and moisture build up under your carrier, it can lead to:

• Fatigue during long wear times
• Reduced mobility and comfort
• Excessive sweating and moisture retention
• Hot spots and pressure points
• Discomfort during training or duty use

For anyone spending hours in armor, comfort is not just a luxury - it directly impacts endurance and effectiveness.

The Bone Chiller helps address this issue by increasing airflow and reducing direct contact between your body and the armor plate.

How the Bone Chiller Works

The Bone Chiller cooling system uses freezable cooling plates that fit directly inside a plate carrier to help regulate heat during extended wear.

Once frozen, the cooling plates create a cooling barrier between the user and the interior of the carrier, helping reduce heat retention and improve overall comfort. The system promotes better temperature management without requiring powered components or complicated setup.

Bone Chiller Features:

• Freezable coolant material
• Approximate weight: 4 lbs
• Up to 5 hours of cooling at 70°F
• Typical cooling duration of 5–7 hours depending on conditions
• Rugged, simple design for long-term durability
• Manufactured using American-made materials
• Recommended replacement interval: every 3 years

Because the Bone Chiller installs directly inside the carrier, setup is simple and requires no permanent modifications.

Designed for Extended Wear Comfort

Extended wear in armor can quickly lead to overheating and fatigue, especially in warm climates or during physically demanding activity. The Bone Chiller was designed specifically to help users stay cooler during long periods in a plate carrier.

This makes it an excellent option for:

• Range training
• Security personnel
• Law enforcement
• Emergency response
• Prepared civilians
• Outdoor workers
• Training environments

The Bone Chiller provides passive cooling without batteries, hoses, or electronics, making it easy to use and maintain.

Important Usage Notes

The Bone Chiller is designed strictly as a body cooling system and should be used accordingly.

Important Notes:

• The Bone Chiller cooling plates are non-ballistic and not stab resistant
• The system is designed only for cooling while wearing a plate carrier
• The Bone Chiller is not a substitute for proper hydration
• If the cooling plates become uncomfortably cold, users should loosen carrier retention straps or temporarily remove the cooling plates
• Monitoring plate temperature helps prevent discomfort or cold-related irritation

Following proper usage guidelines helps maximize comfort and long-term usability.

Compatible With Virtually Any Plate Carrier

One of the biggest advantages of the Bone Chiller is its versatility.

The Bone Chiller is designed to fit inside virtually any Spartan Armor Systems® plate carriers.

Many Spartan Armor Systems® carriers already feature breathable padding and airflow-focused designs, but adding the Bone Chiller can further improve comfort during extended wear or hot-weather use.

Small Upgrade, Big Comfort Difference

Armor plates and carriers are the foundation of protection, but comfort accessories can dramatically improve the overall user experience.

The Bone Chiller is one of those upgrades that many users do not realize they need, until they try it. By improving airflow and reducing heat retention, it helps make extended armor wear more manageable and comfortable.

Whether you run steel plates, ceramic plates, or lightweight composite armor, adding ventilation between your body and your armor setup can help improve endurance and overall wearability.

Final Thoughts

The Spartan Armor Systems® Bone Chiller is a simple but highly effective upgrade for anyone wearing body armor regularly. Designed to improve airflow and reduce heat buildup inside your carrier, it enhances comfort without adding unnecessary complexity.

Compatible with virtually any plate carrier setup, the Bone Chiller is an easy addition for users looking to improve long-term wearability and comfort in the field, at the range, or during training.
