Be your basic self, and don’t give a flying fish. “Based” Thermal long johns and long-sleeve tops are the perfect base layers for winter in Wisconsin or anywhere you’re freezing your butt off. Don’t be shy about rocking long underwear; it’s about staying warm, not “cool".  Made of lightweight polyester spandex keeps you at just the right temperature, wicks away sweat, and fits snugly under anything. No weird lumpy layers here. Comes as a 2-in-1 pack (two tops and two bottoms), so go on, mix and match if you dare. Stay based. Stay warm. Stay weird. Make Grandma proud.
