Rugged gear that’s earned its stripes, the Carhartt 100496BT Force™ high-visibility long-sleeve Class 3 t-shirt is constructed of 4.25-ounce bird’s-eye knit, 100% polyester Force fabric. This hard-working, sweat-wicking and stain-fighting fabric stares down heat and grime; sweat?s about to lose its wet. The t-shirt’s also built with 3M™ Scotchlite™ Reflective Material-5510 Segmented Home Wash Trim, which is segmented for superior breathability and durability plus an enhanced range of motion. In addition, it maintains its performance through 75 home launderings. There’s also a rib-knit crewneck collar and cuffs plus a handy left-chest for tools, pens, glasses and more. The tagless neck label eliminates chafing and side-seamed construction minimizes twisting.
