Fruit of the Loom Men's Classic Thermal Underwear Top
I got these on clearance. I figured I had little to lose for the price I paid. Shock of shocks they are just about as warm as my expensive Jockey brand thermals and (for me) more comfortable fitting. I don't care for skin tight thermals that feel like you are in a vice. These serve me well in all but perhaps below zero temps when I go for the Jockeys.
