Jack Adams Lumberjack Union Suit - Men's One-Piece Thermal Underwear for Winter, Hunting & Outdoor Work - Heavy Duty Flannel Long Johns with Button Front

Introducing our Lumber Jack Union Suit.  Wear them everywhere you want to be, under your jeans when you hit the streets or next to a roaring fire on cold morning.  The snap closure is innovative in the way that it runs down the chest and then all the way around the back - to just above the butt.  It looks much sexier and more sophisticated than any flap ever could!  You won't want to take it off, thanks to the super-soft cotton/elastane fabric.
