Men's Baselite Heated Base Layer Shirt

Built for warmth without the bulk, the Baselite Heated Baselayer Top is your go-to first layer for cold days. With a lightweight crew neck design, soft knit outer shell, and smooth lining, it fits comfortably under any jacket—or stands strong on its own. Flat stitching and in-seam thumbholes provide a clean, secure fit, while 3 heat zones deliver consistent warmth where you need it most.
