    Thermal bottom

    The thermal bottoms did not fit well, rode very low on my waist. The bottoms gave me extreme plumbers butt. Very well made,nice fabric. But odd fitting.

    Thermo bottom

    This 2X size is more of a Medium. Every thing else was +- perfect. Experience many years ago, size was right. Recommend ordering two sizes up.

    Polar king thermal bottom

    The medium regular was way too small. I was expecting a snug fit but couldn't get my feet through the legs . order at least one more size up. They look warm and good quality though.

    Sizing was WAY off. TOO small

    We had purchased thermal bottoms from Key in the past and loved them. However, these are Polar King and are totally different. They do not fit at all. Too small and too short.

    Super long johns

    Heavy weight material. Great elastic waist band. I mixed up my reviews. Both top and bottoms are first rate and will keep me toasty when the time comes
