Polartec Delta™ is a fabric technology designed to work with the body's natural cooling process. Performance efficiency is knit into patent-pending yarn structures that increase airflow, reduce wet-cling and enhance wicking in the hottest environments. Learn More
Polartec Power Wool™ fabric is a one-of-a-kind, natural and synthetic knit. Using our proprietary bi-component knit, Power Wool™ places each distinct fiber where it can perform to its greatest potential. Learn More
Polartec™ Power Dry™ is an advanced next-to-skin moisture management fabric. By using our proprietary bi-component knit construction, every fiber works with maximum efficiency. Moisture is quickly pulled away from the body and transferred to the outer surface for faster evaporation during activity. Learn More
Polartec™ Power Grid™ is engineered to optimize warmth, breathability and reduce fabric mass. Our patented grid construction creates targeted touch points for wicking and open channels to increase airflow to enhance thermoregulation. Learn More
Polartec™ Power Stretch™ is a performance-fit fabric platform that raises the bar for stretch fabric capabilities. Advanced dual-surface knit construction gives Power Stretch enough tensile strength for durable shape recovery. Performance wicking abilities mean it keeps up with any activity. Learn More
Polartec™ Power Stretch™ Pro fabric is an abrasion resistant knit technology that delivers stretch and recovery performance. This fabric is engineered with an enhanced, resilient 4-way stretch capability to enable full range of motion without losing its form. Learn More

In 2013, Polartec started developing FR technologies for the Military to offer a solution for knit uniforms melting when exposed to intense heat in combat environments. Several of our Polartec fabrics have FR versions for added protection in layering systems along with other core fabric performance characteristics.

Polartec™ Power Dry™ FR fabric technology sets a higher standard for next-to-skin moisture management. Polartec™ Power Dry™ FR proprietary bi-component knit construction promotes mechanical wicking to build in performance for the life of the fabric. Learn More
Polartec™ Power Grid™ FR is engineered to optimize warmth and breathability, while reducing overall fabric mass. Our patented grid construction creates targeted touch points for wicking and open channels to increase airflow, enhancing thermoregulation. Learn More
Polartec™ Power Shield™ FR is a soft shell that combines breathable comfort with performance weather resistance and flame resistant protection. The resilient 3-layer fabric's microporous membrane easily releases excess heat and moisture vapor for dry conditions inside and out. Learn More
Polartec™ Power Stretch™ FR fabric allows full range of motion, without losing its form. This flame resistant construction delivers resilient 4-way stretch and recovery for the life of the garment. Learn More
Polartec™ Thermal Pro™ FR brings flame resistance to the original synthetic fleece. This now classic thermal technology delivers breathable performance, soft comfort and long-lasting durability. Learn More
Polartec™ Wind Pro™ FR is an advanced fleece knit developed to resist more than just the cold. While still air permeable for breathability, a tighter knit construction protects against the wind and outside elements. Learn More

Polartec™ invented the modern synthetic fleece, and our Polartec insulation line offers a wide range of fabrics designed to keep warfighters warm. This includes options from the latest in knit constructions and advanced fleeces, all engineered for lightweight, comfortable warmth without losing breathability.

Polartec Alpha™ active insulation regulates comfort in changing conditions. Engineered for consistent warmth, Polartec Alpha allows greater breathability during activity. This air exchange technology creates sustained comfort without shedding layers, which is not an option during the start/stop nature of combat. Learn More
Polartec™ Fleece is the original synthetic fleece, forever changing what we wear in cold weather. This proven thermal technology delivers breathable performance, soft comfort and long-lasting durability. Learn More
Polartec™ Hardface™ is a patented fabric surface treatment applied to enhance durability. Fused at the fiber level, Hardface™ technology increases abrasion resistance and reduces snagging. Select Hardface™ styles are available with DWR for durable water repellency. Learn More
Polartec™ High Loft™ brings our fleece fabric's thermal performance to even greater heights. Our patented, high pile knit construction retains body heat in large air pockets for ultra-soft and compressible comfort. Learn More
Polartec™ Wind Pro™ is an advanced fleece developed to resist more than just the cold. While still air permeable, a tighter knit construction protects against the wind and outside elements. Learn More

Polartec™ weather protective fabrics stand up to the harshest wet, windy and cold environments. We engineer breathability and comfort into these fabric technologies and set the new precedent for how today’s protective fabrics perform with the human body and against the elements.
