FireLine® Multi Mission Zip‑In Fleece Liner

Style #56301

Designed for extreme versatility, the FireLine® Multi Mission Zip‑In Fleece Liner delivers added warmth, flame resistance, and rapid moisture management. Driven by Polartec® Power Grid™ FR fabric, its bi-component knit pulls sweat off the skin while open-air channels regulate core temperature—giving you maximum thermal protection without the bulk. Whether worn as standalone station wear or integrated into your Multi Mission Field Coat or Tactical Jacket, it delivers a sharp, professional appearance built to respond.

Fabric Description:

Polartec® Power Grid™ FR is a lightweight flame resistant grid fleece, designed to optimize and regulate body temperature for intense heat conditions. The proprietary grid fabric construction bi-component knit wicks away moisture and transfers it to outer layers for fast evaporation. It's grid design creates open air channels to increase breathability and reduce bulk, while enhancing thermoregulation.
