  • Warm and comfortable
Size: 4X-Large Color: Navy
My husband drives truck and rides sxs in the winter in the snow. He needed something a little thicker than what he had. UA brand. These aren't super thick but they are very warm. He is a large guy with a big bottom and these fit great. They are stretchy but don't slid down when he bends over to do chains or what ever. They are thicker than the UA brand and much warmer. He gets hot easy and he says they do not over heat him though. He thanks me for them every time he wears them. He is 6 foot tall wears a 3x shirt and 44x 33 pants, I Ordered the four x size (xxxxl) and they fit great without being too tight or too loose. I will buy again if/when these wear out. The stitching is good I didn't find any flubs. I have washed them a few times and dry on low/ultra low and haven't had any shrinkage problems. ... show more

  • Amazing comfort and warmth.
Size: Large Color: Black
This feels like a perfect fit glove when you put it on. Keeps you warm and toasting. Good buy!

  • Comfy
Size: Medium Color: Charcoal
Bought for my spouse. He says they are comfy but on the thinner side. Still decently warm though. If it’s really cold (Minnesota -30) he would wear his thicker ones before these. For the price they are nice. Very soft inside but do pull up a bit after multiple washes. Not bad for the price.

  • Excellent quality, immediately warm
Size: Medium Color: Grey
I've used these on my winter trip into West Virginia Mountains for a week and I use these whenever it's very cold weather around here at home because the heat never reaches my bedroom. These thermal undergarments do their job excellently. They are thick enough and very effective. I can walk around the house in only them, 5 minutes after shivering in my full clothes. One of my housemates is tiny and isn't experienced in dressing warm and I WILL be buying her a set, for the sake of not having to watch her shiver and ignore my advice. For people who don't know, typically artificial fabric is much more heat insulating than natural fabric with the acception of Wool, Cashmere, Down, etc of course. What I saying is when you see that a thick snug garment is made of Polyester, you know it will be warm, especially the way this is constructed. Be careful of cotton, the moment cotton becomes wet it will not hold your body heat against you anymore, it will sap it away actually. There is a saying that goes "Cotton Kills". It will cause you hypothermia when wet. Wool will not, etc. So stick with man-made warm clothing (Polyester filling puffer jackets, Acrylic, etc) or Wool/Cashmere/Down Feathers(Down Feathers must stay dry too though). Stay warm out there! Stay safe! ... show more

  • They are too small.

  • Perfect thermo underwear
These are so comfortable and warming that I bought an extra set. I wear them all day and night during the winter. I highly recommend them. A great product.

  • Top fits small
Size: Large Color: Black
I got a size large so they would fit loose. The bottoms fit perfectly but the top is small. Needs to be longer and bigger. I usually wear a medium in shirts and the large is a bit small. The material is awesome and they seem to keep me plenty warm. I would recommend them
