The FlexRS™ Insulated Base Shirt is a fleece lined base shirt designed to provide warmth, mobility, and professional performance during cold-weather patrols. Combining a durable low-profile FlexRS™ ripstop exterior with targeted insulation, this insulated base shirt keeps officers comfortable whether worn on its own or layered beneath an LBV or ArmorSkin® Vest Carrier.

KEY FEATURES:
The FlexRS™ Insulated Base Shirt is a purpose-built tactical base shirt designed for officers working in cold, unpredictable conditions. Water-repellent bonded fleece on the sleeves, shoulders, and yoke provides targeted insulation and weather protection, while the breathable fleece-lined torso helps retain warmth without sacrificing comfort under compatible Blauer ArmorSkin® Vest Carriers. The low-profile FlexRS ripstop exterior delivers the durability, professional appearance, and easy-care performance officers expect from the FlexRS uniform system.
Unlike bulky outerwear, this fleece lined base shirt is designed to integrate comfortably with body armor and duty gear while maintaining unrestricted mobility. Two chest handwarmer pockets, a double pen pocket, mic tab, and 3-button center placket provide practical functionality for everyday patrol use. Whether worn beneath armor or as a standalone layer, this winter base shirt delivers dependable warmth, breathability, and tactical performance without adding unnecessary bulk.
