Engineered for crisp mornings and cold mid-to-late season hunts, this thermal long-sleeve base layer delivers target thermal insulation while managing moisture during physical exertion. Built with a dual-zone grid fleece lining, it traps body heat around your core while allowing excess heat and vapour to escape through strategic ventilation zones. Soft against the skin and virtually silent during motion, it functions as a high-performance standalone shirt in cool dry conditions (45 °F to 60 °F / 7 °C to 15 °C) or as an essential mid-layer underneath a softshell or waterproof jacket when temperatures drop further. Integrated thumb loops keep the sleeves locked in place when adding layers, while the high-contrast TREEMETIC camouflage ensures seamless concealment in timber and brush.
