Carhartt's Force Midweight Stretch Base Layer Hoodie was made for all those hard-working people wearing head protection at work. From construction site to working from heights, a base layer hood worn under your helmet or hard hat that connects to your base layer top adds warmth to your head, neck, and ears so you can work longer in comfort. Made of polyester blend fabric with two different sweat-wicking fabric technologies, this odor-fighting, thermal shirt helps you stay dry which means warm and comfortable. This long underwear hoodie offers versatility when managing your layers, great for cold days under outerwear, hoods, hats, and helmets or as a stand-alone piece when the weather changes and you need to cool down. Designed to fit snug but not tight, the stretch fabric of this base layer top allows you full range of motion. Customize your warmth with this hooded long-sleeve shirt and for a complete set, there's a matching Carhartt Force Midweight Stretch Base Layer Pant. Look for models UM0301-M and UM0295-M.
