ColdPruf Men's Enthusiast Single Layer Bottom, Black, XX-Large

They are nice in this cold weather.

Fits good, comfortable. I have had warmer base layers though and will probably only use these in the 30+ weather

Very good

These are a great bargan. These are just like the old school long johns and a good value. They are a bit thin, so if I new the company's layer levels before hand I would have ordered a thicker pair. They are in no way Under Armor but they do serve their purpose.

They fit well and keep their shape after washing.

Good thermals

These are thin long underwear and will not be as warm as others made out of heavier material. That being said, for their weight they are very good. These are ideal for active cold weather pursuits, or for more sedentary pursuits in mildly cold weather. For just sitting on a bucket ice fishing, these did well for me under jeans with temps in the 20s (F). If it's 20 below and you're sitting still in such attire, you'll likely be unhappy. They do cling to things...If you have a light-colored dog they'll probably look like you wore them as an outer layer while brushing your pooch, even if you keep your pants on and never pick up the brush.

Very comfortable and warm, but after the first wash I have a seem coming apart
