Poor product!
I have been wearing their former product, called Carhartt Force, 100 % cotton, with a very tight weave., and have been wearing them for several years, and they are outstanding. The Base Force ones were loose fitting, with a loose weave and felt more like pajamas than cold weather longjohns.

Whoever designed these must have a secret hate for men.
I just recently purchased these for work, and at first I really liked the material and fit. But after working a full day in these, I realized that strenuous work cannot be done 100% comfortably in this pair of thermals. The seam in the center of the genital area makes it extremely uncomfortable and causes chaffing. I would highly recommend redesigning ALL of your men's underwear to make this area more suitable for functionality. Just my take on it, maybe others feel different. Other than that I thought the material was very breathable and also warm at the same time, and would purchase 10 pairs if the seam wasn't so awkwardly fitted.

They are loose. Thermals are supposed to be tight. They suck.

Saggy and Baggy Fit
I'm very disappointed in this new version of the 100% cotton midweight long underwear bottom. They do not fit nearly as well as the older version that I loved. They are very baggy, saggy and fit like old man's underwear. They are no longer a waffle material but like a thin corduroy. The old version fit like tights and worked well as a base layer. The new model is so baggy that they bunch up when used as a base layer. These also lack a cuff at the bottom so do not stay in place as well as the old ones.

These are supposed to fit tightly and they are very loose. I’m about 180lbs and I got a medium and they still fit like sweatpants. Extremely disappointed.

Suuuuuuuuck
Size is way off. Large fits like clown pants. And they developed a hole after minutes of wearing them. Carhartt won’t get back to me about it.

Great long underwear bottoms
Wonderful long underwear bottoms. These bottoms are not overly warm but for midweight bottoms they are definitely warm enough. They are long enough for my husband who is 6'4" who usually has a hard time finding pants that actually fit him correctly. He loves the fact that he's able to move around and they don't stretch pull or chafe. Great purchase
