FNDN Heated Skin-Fit Base Layer: These days, 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 lower 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.

At FNDN, we believe it's not about where you are, but where you are from.

There's an old saying that each generation is most like their grandparents. In our grandfathers' America - before the Internet, cell phones, and video games - our "greatest generation" was a well-oiled industrial machine running wide-open with the Motor City at the heart of it all. FNDN's foundation happens to be firmly rooted in Detroit and that same innovative spirit is part of our DNA.

Our products share that same mold our grandparents valued. The industry, the inventions, the manufacturing, and even the music has branded a loyal, patriotic, hardworking ethos into us. Combining quality materials, craftsmanship and utilizing cutting edge technology, we strive to create the finest products available that are both beautiful and functional.
