Loggers, linemen, landscapers...men who work outdoors need Thermal Shirts that are warm, easy to move in and layer under jackets and sweatshirts without steaming them up. Our take on the classic Thermal Shirt for men has a lofty waffle knit that's highly breathable yet warmer because it traps air. The heavy-duty 8.2-oz. weight wears harder and holds its shape, too, even if you keep pushing up the sleeves. For ease in action, we added gussets under the arms of this waffle henley – helpful when you're backcutting a big pine. They also have our trademark Longtail design – 3" longer to keep you covered when bending over.
