A sweater and undershirt top combo for men. These come in two pieces on a shirt and the sweater is on gloves so you can dye them independently and mix and match with your other outfits. The sweater works for highlanders, but the undershirt unfortunately does not. Mimi's \Basics\" mod has a few good compatible undershirt alternatives.
Extreme Survival Shirt and some gloves or another
