Well worth the $$
I was wearing them outside yesterday in -4 degF temps and was very comfortable and warm. They seem well-made, as are most Carhartt products I own. I'm 6'7" and 225 lbs, 38" waist, and they fit very well. I like Carhartt clothes because they usually run a little large and the non-tall sizes fit me fine in most cases. I probably could have gone with the XL instead of XL-Tall, but again... it's better for them to be too big/long. Most other clothing brands I buy fit well until I wash them, then they shrink.

This is the perfect base fit
Figuring that (as of writing this) this winter is probably gonna be very bad, and having an outdoor job, i needed an upgrade from my casual thermal pants (if we even wanna call it that), and this DELIVERS. I wore it under my usual work clothing, and it did its job at keeping me comfortable in the cold. It was practically very light to wear and keeps a practically invisible profile under your work clothes. Would recommend

A bit thin, but otherwise well made
Good fit, does provide some warmth, although a bit thin for a midweight.

It was the best out of four brands I tried.
Tried three other off brands but the Carhartt brand felt the best and most thoughtfully designed.

Keeps me warm when I go outside in winter. Fits me well and I’m 6’4 The big feature is that the inseam is 33” long although I could have used an inseam of 34”. But I’m satisfied.. although I find the price a bit too high. So I won’t be buying more and will look for alternate suppliers..
