FNDN Heated Skin-Fit Base Layer - Unisex



    FNDN Heated Skin-Fit Base Layer


    Product Description

    In today's day and age, having a closet consisting of cutting-edge capability is the name of the game. We’ve designed a heated, skin-fit base layer that is made from an extremely lightweight, breathable, stretch technical fabric.  The long sleeve, hooded base-layer with thumb hole cuffs is so versatile it can be worn under your favorite shirt, sweater, jacket, or simply by itself to provide enough warmth as a parka jacket without the restricting bulkiness. Control every zone with this heat-on-demand base layer. 

    FNDN soft-touch control buttons are capable of providing you with three different levels of heat in multiple heated zones. Stemming from your hands, back of your neck, then throughout the upper and center back regions. 

    No matter if you work or play outside in the winter temps, turn to the Foundation Heated Base Layer for all-day heated comfort.  

    The unisex cut is designed to fit both Men and Women. Please see our sizing chart to determine the best fit for you.
