gave this as a gift to someone who does NOT like thermal undies but he raves about these!  they are not the old fashioned waffle-weave, scratchy your-granddaddie's-long-johns!! perfect weight for under jeans, slacks and even sweats, especially for cold-natured folks or those baby boomers whose thermostats are running lower these days! they are handsome & fit close to the body with moisture wicking for mild to moderate activity... they're currently on several people's wish lists for Christmas!
