FITEXTREME Mens MAXHEAT Soft Fleece Long Johns Thermal Underwear Set Grey M

I'm slender and these are snug. The bottoms are pretty good but I have super skinny lower legs. The top fits good around my torso (skin tight) but on the arms it CONSTANTLY pulls up your arm and bunches, and then it's nearly impossible to fish the sleeves back down because you're wearing this under your other clothes. May not have this issue with your average sized fella. The top and bottom didn't match exactly which was a bit disappointing. They liner is the same but the shell has a variation in material and color.

The tops are way small. The bottom is cut for someone with very skinny legs, no butt, and a large beer belly.

Only reason why I did not give it a 5 star was because I order a medium but it was a little too small. I know they were suppose to be tight but medium felt like a small a bit. But overall it does it purpose and keeps you warm for skiing.

I make frequent trips to the Northeast which is known for being cold as satan's balls at times. This thermal so far has given me the ability to participate in regular outdoor activities, including sports, with no real regard for the cold. They're very warm, I prefer to wear light clothing over them, or simply to keep the shirt exposed (looks a lot like an under armour shirt).For context: I'm 6'2, 165 lbs, fairly athletic/lean, and the medium fit me perfectly.

It fit to size and no overly tight or loose spots. Kept me warm under light clothing to mid fifties and used as sleepwear under a blanket down to high 40's so quite pleased. Don't like to feel weighed down with clothes so this way stay warm while layering lighter clothes for more flexibility in movement without feeling like the Michelin man walking.
