Details: And so the thermometer is telling you that it’s a bit brisk. Well, that never stopped a carhartt base force cold weather bottom from getting the job done. It’s made of 4.5-ounce, 100-percent polyester midweight knit and is unique in that it not only wicks away sweat, but it also fights odors.it has smooth flat-lock seams for comfort. A drop tail adds coverage to your butt and tapered cuffs keep in the warmth. The elastic waist keeps in the warmth. It goes well with the base force cold weather crewneck top. They were made for each other. Like beer and pizza.
