  • Love the fit
Size: XX-Large Color: Shadow Heather
Heavier that normal base layers but comfortable. Very warm without bulky feel.

  • Quality Product, Great Fit
Size: Large Color: Burnt Olive Heather
The title of my review are the exact words of my husband…..the pickiest man on the planet when it comes to clothes. I bought him this shirt for Christmas, hoping he would wear it as an undergarment for extra warmth when he was working outside in our cold Northeast winters. But he loves its style, fit, and stretch so much that he wears it as a regular shirt and fashion statement. It fits perfectly according to the sizing guidelines. He has also worn it as I intended….as an extra layer for warmth outdoors…. and he says it does keep him warmer without producing a sweaty feel like some other long john types of garments. If you knew his fussiness about clothing and how many items I have had to send back or return, the fact that he loves this shirt to this extent is a testament about its awesomeness. Looks great with a pair of jeans, and he wore it to two social gatherings and was complimented several times. I have now purchased 3 more for him in other colors. ... show more

  • Not bulky and a good added layer
Size: XX-Large Color: Navy Heather
Nice thin thermal. I usually wear it over a t-shirt and under my FR work shirt on slightly chilly shifts.

  • A bit small for a Carhartt.
Size: Medium Color: Fired Brick Heather
Love the Carhartt brand, but at times I even have to size down as they seem to run large. I'm 5'8" and 170lbs and this medium was a bit SMALL. It fit well in the arms, neck and waist but was tight in the chest.

  • Carhartt thermal underwear
Size: X-Large Tall Color: Navy Heather
When you have to be out in the cold it makes good sense to be wearing thermal underwear. Thermal underwear makes the difference. Mid-weight or heavy weight the quantity and comfort is just there.

  • This is actually heavyweight
Size: Large Tall Color: Fired Brick Heather
Bought this for my son who has nerve damage in his arm. I first bought the black. Titled heavy weight, it was not. I received this pkg and it's literally more than double in size. I now returned the black. I only realized this AFTER reading reviews. Which in reality the blue and grey ones I bought last year were medium weight as well. I currently bought the green. Waiting on that one to see if I actually do get a heavy weight item. * ... show more
