FIRST LINE OF DEFENSE

Engineered for cold conditions, the ThermoFlex LS Base is your first line of defense against the elements. Built with ThermoFlex fabric, it delivers compressive four-way stretch for a locked-in, second-skin fit that never bunches or shifts under layers. The brushed interior boosts thermal retention while advanced moisture transport pulls sweat away from your body fast—keeping you dry, warm, and operating at peak efficiency. Lightweight, breathable, and purpose-built to regulate heat when intensity rises and temps drop.
