Review on Stay Warm And Cozy: Men'S Fleece-Lined Thermajohn Long Johns For Extreme Cold Weather by Ken Reiff

Very comfortable and fits well. I'm 5'10" / 200 lbs and large fits perfect. Not as thick as I hoped but I'm keeping a good product. Makes a great, thin, base layer and the material wicks moisture pretty well. With another shirt on top and regular denim pants, I was comfortable mid 30's while moving about. Probably a little cool just sitting. If you are looking to go ice fishing, these will be too thin.
