Keeps out the chill
I purchased this shirt to wear at night because we keep our bedroom cool. Wearing this with a sweatshirt keeps me very comfortable when the room is at 63 degrees Fahrenheit. Well-made, nice material, and light weight. My size is between a medium and large, so I ordered the large because other reviewers noted that the sizes tended to be on the small size. It fit like a charm, and I have ordered another one.

Very comfortable thermal shirt
Bought two cause of outdoor work. Fit true to size. Soft, comfortable and warm. Does not absorb sweat or get out of shape. I got black and works fine for me. No shrinkage that I can tell and I put them in the dryer. Worth it. Down side was I ordered two more in mock neck, same size and neck is too tight. Drives me up a wall. Get the crewneck.

Two thumbs up!
Got this for my husband for Christmas and he totally totally loves them. They have a really thin layer of fleece on the inside without being bulky, and kept in nice and warm here in New York in 25° weather.

Very comfortable and will keep you very warm
I was worried about the material being itchy like other thermals but I found the inside of the shirt to be coated with a very soft material and its in no way itchy . I actually ordered a total of three shirts in 2 days after the inital order. The only drawback is the run a lil small so if you are in between sizes go up to the larger size. I normally wear a M but i could have ordered a L . Other than that they will stretch to fit .

Decent Warmth but Quality Could Be Better
I purchased the Thermajohn Thermal Shirt to use as a base layer during early morning runs and colder commutes. While it does a fairly good job at providing light insulation and warmth, I was a bit disappointed with the overall quality of the material. The fit is snug and the compression feel is comfortable without being too tight, which I liked. It works well for layering under jackets or hoodies and does help retain body heat in moderately cold weather. However, after just a few washes, I started to notice some pilling and loose threads, especially around the sleeves and seams. The fabric also started to lose some of its stretch, which made it less comfortable over time. Additionally, the stitching on one of the sleeves began to unravel, which was frustrating considering I hadn’t even worn it for heavy activity. While it’s still usable, I expected better durability from a product designed for cold-weather performance. If you're looking for a budget base layer for occasional use, it might do the job, but if you need something long-lasting and durable, you may want to consider other options. Three stars.
