Power Grid™ FR

technical fleece

Polartec® Power Grid™ FR is the evolution of fleece fabric engineering.

Our patented grid construction knit strengthens performance efficiency by increasing warmth and breathability, while also reducing fabric mass. These geometric patterns improve compressibility, wicking, and add technical style. By reinventing thermal warmth possibilities, Power Grid™ FR is a minimalist design that maximizes fabric performance.

Engineered for Comfort.

About Power Grid™ FR Technology

How did Polartec® make Power Grid™ FR do more with less fabric?

With geometric constructions to generates targeted touch points for our patented bi-component design to manage moisture. The next-to-skin surface is hydrophilic to absorb sweat vapor and transfer it outside. Then the outer surface disperses moisture for more efficient evaporation. The grid design also creates open air channels that improve breathability, and reduce fabric mass.

Ergodyne x Polartec®: A New Flame-Resistant Dual Compliant Balaclava

Ergodyne has launched their new flame-resistant (FR) balaclava, the latest addition to their N-Ferno® line of cold-weather gear. Built using Polartec® Power Grid™ FR, the new N-Ferno® 6847 Dual Compliant FR Balaclava Face Mask meets two flame-resistant standards, both NFPA 70E and NFPA 2112, and is one of the only balaclavas in the industry that is 100% compliant with both specs – not just partially constructed with compliant materials. It’s rated to protect against both arc flash and flash fire, making it an excellent choice for those working in electrical, utilities, oil and gas, petrochemical and other similar industries.
