My son loves his! He is a bit tall, so the legs are kinda short, but since its under-wear it doesn't bother him.

    • Good value for the money
Size: XX-Large Color: Grey
I work outside everyday and wear thermals everyday. They are not the best but will work for those cold but not frigid days. The biggest complaint would be the wrist and ankles openings are way to big and do not keep the cold air from entering. Size wise I purchased 1X and 2x. I am 5'-10" and weigh 200 pounds. I have a 44" chest and 38" waist and the 1X is the better fit. The top is just snug and the bottoms are a little large. 2X would fit someone much larger. ... show more

    • The pants were shorter then expected
Size: Small Color: Black
Product came as pictured they are stretchy. My boyfriend likes them I got them to go under his bib overalls to stay warm at work. Today is the first day of him wearing them to work so I'll update the warmth when he tells me. He slept in them last night and said they are comfortable he said it's like men's leggings 🤣 ... show more

Fits great kept me warm and cool soft and durable. These are not scratchy like other kinds. I will be replacing my old ones for more of these! I drive semi trucks and deal with winter weather and by far have been the better thermals! Two thumbs up!
