ThermajohnLong Johns Thermal Underwear for Men V Neck Fleece Lined Base Layer Set for Cold Weather

My husband wears these to work under scrubs for comfort in an air conditioned climate. He loves them.

Per their instructions, ordered one size up and the fit was outstanding. Comfortable for long hours on a chilly morning hunt. Made it through a couple of mornings in the teens while turkey hunting with comfort and warmth. I'm quite pleased. Four stars as I'm not sure how they will hold up, but I don't need them often and they did all I needed.

Feels like you don’t even have them on but keep you nice and warm.

I bought these to keep warm, as you do. I wore them under a short-sleeved t-shirt and jeans. When I took them off after 6 hours of wear, the material was already pilling and has only gotten worse. Under a light-weight shirt it looks as though I need to seriously shave my chest...and I'm a woman! Bottom line - good for warmth, bad for aesthetics.

I live where its warm most of the time and needed something for the rare times I visit the cold. This did the trick and cost way less then other options

Great stretch material keeps me warm in the extreme cold weather.

On Christmas of 2022, Pope Francis urged the world to "Do something good this Christmas", partnering with Eppella to take donations to provide Ukranians with thermal shirts, to help them survive the hellish cold of a winter without power (thanks to Putin's attacks on their power grid). I decided to get myself a few sets of thermaljohns (tops and bottoms) to test how effective they are. I'm writing this review with the heat turned off, at 58 degrees F inside, 23 F outside, wearing a thermaljohn shirt and pants, sweat pants, sweat shirt, zipper hoodie, and beanie for my shaven head, and I'm perfectly comfortably warm! These will pay for themselves in a single month in lowered power bills.

very comfortable and warm
