Go Athletic Apparel Men's Long Sleeve Thermal Underwear Shirt for Cold Weather; Base Layer

Perfect thermal base layer!Fits tight as advertised. I'm 6' 155lbs and normally wear a Medium (39-42) but ordered this in a Large. It's a close fitting but not compression shirt that is next to skin like a good base layer should be.Only complaint is the mock neck. It's a bit tight and somewhat impractical. I feel the shirt would be a lot more versatile if the mock neck was reduced to a regular shirt neck.

Good product. Hugs the body and feels abundantly full featured. This Mock neck fit has a relaxing feel and keeps the warmth in from the neck down. The quality has to be experienced and before you know it you'll just GO with it. I tried many others and searched to the far reaches of the Apparel world to come to this brand and felt like I finally reached the correct destination with the GO offerings.Overall, I am pleased with the thickness and softness of the material as it feels like you are getting what you pay for.

The fit is snug, the collar fits against the neck giving no space for cold air to blow in from some gusty winds we had here lately. I got a medium and the arms have about 1/2 to 1 inch spare, as for the length my fear of it being too short was way off the mark. I can pull it down over my hips and I stand 6 feet tall. So you won't have to worry about it riding up at the wrong moment.

I bought two of these shirts for the same price as one Under Armor shirt of similar quality. Go Athletics is made in America.. Under Armor is made in China. I hear Under Armor is going to start making some of their products in America.... I can only imagine what their stuff will cost without Chinese slave labor. I'll take Go Athletics any day, all day long.

This is the best base layer clothing I have ever purchased (and I have 3 boys, so I have purchased a lot). The other brands are just brands, and as such you pay a premium for clothing that is made in china.Go Athletic Apparel is far superior, and at half the cost, it is a no-brainer. I wouldn't buy anything else.Plus, it is made in the USA.

Great base layer and very durable. It kept me warm, and because I sweat in the cold, it acted like a wet suit by the time I was done with my run. Other reviews says it's better than UA. For half the cost, it got my vote! I will buy these again!

Outstanding item, super quick delivery, highly recommend.

This will keep your warm. It is heavy no doubt. I where that and an older snowmobile suite in 30 below snowmobiling does great. By again. Yep! 6’4” 255 lbs 3x fits fine.
