Recognized the higher quality as soon as I removed it from the sealed plastic bag it arrived in. Looks great, feels great. Designers made sure there was sufficient sleeve length and abundant shirt length to avoid unwanted cold drafts.
My con: "expected more warmth" is because everything about the Jockey brand has been over-performance. Since my first purchase of the Jockey brand (in the mid-1990s) and throughout the years since, my Jockey garments have always out-performed my expectations. There is no flaw on the part of Jockey; I simply expected more than the typical warmth from a similar type of garment.
I was looking for a couple of long sleeve thermal shirts and stumbled upon Jockey's website. Found one that I thought might work at a good price point - less than $20.00. Excellent fit and great value.
I bought this shirt last year and it had a red inner lining under the crew collar. This year it did not so I knew immediately it was different. It was thicker last year and was tighter in the chest and arms and more loose around the waist so it looked flattering. This year it was cut different so it didn't have the same shape. It can still function as an undergarmet, but I would not personally wear it as a stand alone shirt as I did before.
This thermal shirt is well-made and keeps you warm, but... I was allergic to one of the materials used to make it, probably the Spandex. About a week after wearing the shirts I developed red, itchy spots around my wrists and ankles--places where the fabric was closest to my body. This has never happened to me before. The spots went away about three days after I discontinued wearing the shirts and leggings.
