The Ergodyne N-Ferno 6435 Thermal Base Layer Long Sleeve Shirt features medium-weight stretch fabric with a brushed interior for warmth and comfort. Thumb holes keep the shirt in place and block wind, while moisture-wicking treatments transport sweat away from the body so workers stay dry and comfortable in all temperatures.
Built for jobsite safety and performance, this base layer includes UPV 30+ UV protection, 3M™ Scotchlite reflective accents for high-visibility, and anti-odor treatments that inhibit the growth of odor-causing bacteria — making it ideal for demanding outdoor and industrial work environments.
