I received the thermals as part of a Carhartt Crew Field Test. They are much thinner than I anticipated but more than make up for it in functionality. They are very comfortable to wear and keep you warm in very cold windy temps as a base layer and are very breathable as I also wore them in an office setting in a temperature regulated building and did not overheat. I've owned several base layers in the past and these have been the most comfortable by far.

If these are the 'heavy weight' I'd hate to see the light weight. A long sleeve cotton t shirt is just as warm and half the price. This is the first Carhartt product that I've been disappointed with.

I bought these for my father because he’s always cold. We’ve had a hard time trying to find thermals that fit his long legs and arms and these worked out perfectly.

This is a great, comfortable base layer. They are warm and soft super cozy I have even slept in them. I got these as part of the carhartt crew test. I would recommend to any one.

My husband loves these!! He practically lives in them. When working on the farm you find yourself running in and out of equipment during those cold months. Just a heads up they will shrink if put in dryer!

[This review was collected as part of a promotion.] I always am happy with Carhartt products. However they are listed as HEAVYWEIGHT, not really I wore them for the first time yesterday in 9degree weather. Didn't really keep me warm for HEAVYWEIGHT thermals. Super comfortable though.

These are great but could be a little tighter at the ankle

[This review was collected as part of a promotion.] Super comfortable, easy to move in, no chaffing, plenty warm for the coldest days

Product is very warm, and very light feeling when wearing it. But it's very uncomfortable in the couch area.

Super warm and perfect fit. Would definitely buy again.

[This review was collected as part of a promotion.] Very warm, comfortable and lightweight. It fits nicely with no suffocation.

Disappointed, suppose to be heavyweight and keep you warm. Does not perform as advertised. Do not recommend!

Great, but think about adding elastic cuffs and lengthening the inseam a few inches on the large tall bottoms. Men are taller today than they were fifty years ago. Love your products and wear them daily!

These are no where near heavy weight. I can see right through them. I have a pair from years ago that are heavy. I don't know what happened to Carhartt recently but these are garbage.

Loose fit. Was hoping for same quality/fit as quarter zip upper

I am very disappointed in the quality of the bottoms and in my opinion way over priced. I bought the top and although not a wool blend, it is made very well and of high quality. I regret paying as much as I did for the bottom.

These are heavy enough to keep me warm, but light-weight to fit under work pants.

My husband needed a new pair of long underwear for work, and he loves them. He definitely feels warm in them!

I like the base force line of base layer thermals. The only reason I didn't give them a full 5 stars is because they do itch some. But they work.

I ordered the medium size bottoms, they are a perfect fit for my 5’6 165 lbs frame. They have kept me warm lately when the temperature dropped below 40 degrees, i was disappointed with the color, I ordered black, they look more like dark gray.

I received the poly-wool crew shirt as part of a Carhartt Crew Field Test. I love the high quality stitching in all Carhartt clothing including this one, it held up really well and is the most durable base layer I've ever worn. The fabric is extremely warm and the fit is great, didnt feel as restrictive as other base layers I've had.

Just don't keep you warm, disappointed with this item.

although I got the wrong size and they’re a little tight. They’re still usable and so far they have been pretty warm this winter

I cannot believe how much it kept me warm. I am impressed with the overall fit and functionality. Does not feel like your regular tight fitting thermals. Loose enough to breath, but tight enough to keep you warm.

[This review was collected as part of a promotion.] My grandson loves the feel the fit the comfort of these thermals he also loves the thumb ring at the end of the shirt sleeve he said it's easy to keep it down while he's putting on other layers.

cant order this item..whats going on? did they discontinue? not good

Runs too small for the size. The waist / seat is too shallow.

I love these base layer pants. They are snug so not to feel to baggy under clothing. I work in freezers on a daily basis and need something light and warm to perform the functions of my job. These have hit every mark and then some especially when I’m in a -10 freezer working and not have a chill at all wish they had these in socks though. I highly recommend these.

Great feeling material, perfect rise, great fit. These don't loosen up and sag in the crotch like old school thermals did when they got wet/sweaty. They wick sweat away before you get the cold clammy feeling.

Warmer than you would think based on how thin they are. Very comfortable.
