Strong, Durable Midweight Thermal Shirt
I have the top and bottom combo and love them! They're heavy and warm enough to wear under a t-shirt or under a sweatshirt but cool enough to not make me sweat. When the temps got above 45 degrees I did quickly get hot but that was an environment issue and not a problem with the thermals. The thumb loops were great when layering under another long sleeve shirt. One of the most irritating things to me when wearing a base layers is the arms right up when another shirt goes on and this setup prevented that from happening. The shirt was a little shorter than expected and came untucked when lifting above my head a lot but that is a very small issue. I will buying another set for hunting this fall.

A new classic
A mix of classic styling and modern materials. The fabric feels smooth and comfortable against your skin. It breathes well. The fit is a bit shorter/tighter than typical Carharrt sizing, you may need to upgrade to a tall size.

You have tried the rest, now try the best
After using cheap, no name base layers for the longest time i was given the opportunity to "field test" through Carhartt Crew these base layers and i gotta say after buying cheap base layers the proof is in the pudding these base layers are great and make working in these harsh conditions much more bearable.

This is a nice thermal to wear in earlier winter. It keeps you warm without overheating. It is comfortable to wear and still looks new after several washes.

Warmth Without Bulk
I RECEIVED THIS SHIRT AS PART OF THE CARHARTT CREW TO FIELD TEST. SOMEHOW, CARHARTT WAS ABLE TO MAKE THESE THERMALS MUCH WARMER THAN TRADITIONAL THERMALS WITH HALF THE BULK. THEY ARE EXTREMELY COMFORTABLE WITH THE EXCEPTION OF THE CROTCH BEING A LITTLE TOO "SHALLOW" FOR MY LIKING, BUT THAT COULD JUST BE A MATTER OF OPINION AND PREFERENCE. FOR THE 2 MONTHS I HAVE BEEN FIELD TESTING THESE, THEY HAVE HELD UP EXTREMELY WELL THROUGH MULTIPLE WASHES IN ALL TEMPS AND TYPES OF WASHES. THESE WOULD BE A GREAT ADDITION TO ANY DRAWER!

Quality and functionality mixed
Like an ideal pair of underwear. No complaints and they do keep you warm without causing a sweat that can make you even colder.

Good looks & Warm too
As a member of the Carhartt Crew I was asked to review these thermal pants .
They have worked great and kept their shape and look like new after 2 months of regular use here in the north.
Very comfortable and nice weight for mixed outdoor/indoor use without overheating.

Good Mid weight pants
Good mid weight pants. feel more like a sweat pant comfort wise. kept me warm in low 30s weather and did't over heat me when it warmed up. The cuff of the pant was too loose for me. I like a tighter fit around the ankle. Overall did its job for a medium weight Thermal pant.

Nice Thermals
I received these thermal pants as part of my participation in a Carhartt Crew Field Test. I wore the thermals approximately 15 times and washed them after each use. After all those washes the pants had no noticeable shrinking, which I thought was excellent for a thermal. The pants fit very well. I got the mid-weight pant which worked very well for warmth. It kept me warmer than just my washed duck pants but breathes well so it works great when doing manual labor.
