Don't fit as well as the older Carhartt

I'm a retired plumber and a long time Carhartt fan. I have 3 pair of my favorite Carhartt long underwear left that fit like a second skin, The ones I got from you last are so baggy when you pull up your pants they wad up and come up with the pants. I didn't return them as they're better than nothing but if I could get some more like my old ones I'd buy more.

These are great but I wish there wasn’t a seam right down the middle of the genital area. Makes it very uncomfortable when moving around all day in a working environment.

Just the right amount of insulation. A bit loose at the ankle. Would prefer a smooth fabric over waffle weave.

This is my favorite thermal brand. I work construction and I am able to comfortably work and move all day. I forget I am layered and have thermals on. The stitching is well made and the material is comfortable to wear.

Very nice lightweight base

From: HAZEN, AR Age: 45-54 Gender: Male
The lightweight bottom is a very good product to start your layering in cold weather if it is warmer you can just use the lightweight alone under pants or even alone in coveralls. They do not ride up or slip down and the fit is great. I received the pants as part of a Carhartt Crew Field Test.
