Bulwark
Upgrade your crew with the Bulwark MPS4 EXCEL FR two‑tone base layer, a rugged yet comfortable work shirt designed for demanding environments. Made from a 90% cotton/10% polyester blend that weighs 5.5 oz, this shirt wicks moisture, stays breathable, and meets CAT 1 flame‑resistant standards so you stay protected on the job. The tagless crew‑neck eliminates irritation, while the concealed chest pocket and pencil‑stall keep tools handy without adding bulk. Contrast mesh side‑seam gusset adds durability where you need it most, and the heat‑sealed Bulwark triangle at the neck signals you’re wearing FR gear. Because the fabric is smooth and stable, it takes DTF, screen printing (24‑piece minimum), and dye‑sublimation with crisp results, making it perfect for branding your business or team. Available in two classic colors and a full size range up to 5XL, this shirt is ideal for contractors, electricians, and any workforce that demands safety, comfort, and a professional look.
