The Thermal Base Layer is designed to provide advanced thermal protection for aircrew operating in cold environments. This high-performance base layer traps heat while allowing moisture to escape, making it ideal for rotary wing and non-fast jet aircrew who require both warmth and breathability during extended missions.
Constructed with lightweight, breathable fabric, the Thermal Base Layer fits comfortably under flight suits and other protective clothing, offering a critical layer of thermal defence against the cold without compromising mobility or comfort. Whether operating in maritime, mountainous, or high-altitude environments, the Thermal Base Layer ensures aircrew can focus on their mission without the distraction of cold stress.
