  • You know those glasses cleaning cloths? It's like that but thicker
Much thicker at that. I received these before I had to head off to work, which was quite awesome because I didn't have to work in the outdoors for the 12 hour shift thinking of fire-places and heaters all day in the sub-zero weather. When I first put them on, they felt a bit snug, but these are a base layer, so it was to be expected, but as thick as these are compared to my waffle knit, it was something I had to get used to. I was noticing them for quite some time during my shift, but eventually grew numb to the feeling of being hugged by spandex. I felt like I was wearing a dive suit, but with a soft lining interior and fabric exterior. For the performance, they performed quite well, not quite the 3 layers of fleece blanketing next to the radiator that I was hoping for, but far exceeded wearing 2 sets of waffle knits just to put off the cold a bit longer. As I stood outside, I felt as if I should have been sipping on something from a mug clasped with both hands, but I don't really think a man should ever hold a mug with both hands ever, so I held mine with just the one. I stood outside for a good 2 hours without working up a shiver, and never even came close, I felt like i could go another 10 hours or more. I would say after 20-30 minutes, if you're not shivering, you're never going to, unless the wind is blowing... really... really... hard, or you're skydiving, which neither of those things were happening, a few gusts here and there, but these didn't break a sweat. Speaking of sweat, they do not get you really hot either, they do a fantastic job at regulating your body temperature, unless you're sitting in a heated cab, they aren't going to bake you. Some additional thoughts. I'm not going to remove a star over this, because everyone has a different shape and size. I went by the sizing guideline, and I was right there at the line of L and XL, me being 6'1" and 185lbs, my gut told me XL, but logic and research said L. I went with L. while the pants and main shirt area are just the right size, the sleeves seem to ride up my arms a bit. It feels like the sleeves came off a medium shirt while the rest were stitched as large. I have received comments on my rather long arms in the past, so it's definitely my body's problem, because for some reason, I've been given XL arms for my regular L body. If anyone want's to trade arms, let me know. ... show more

  • Runs small
I bought the navy blue medium set for me. I am 5'1 weigh approx 160. The length is perfect for the top and bottom. The fit overall is rather on the tighter side. That Im not fond of! The lining is very thick and soft! That part I really love! If you were brought up in the 80's when clothes were thick to begin with then this is truly what you are looking for! The next time I order this it will be an extra large or bigger. I feel they run a bit small. ... show more

  • Thick, warm, soft, fits well
I bought this for a family member who has health issues and gets cold easily. We were instantly impressed by how thick, soft, and well made the product is. It is very effective at keeping him warm. He calls it "the wet suit." It's also convenient that it can be washed and dried in the machine.

  • Quality Heavyweight Thermal Underwear Set
I live in the upper Midwest and during the winter months I often spend time outdoors shoveling snow etc. and I need a good quality set of thermal underwear to get me through the cold days outside. Searching through the vast quantity of thermal underwear available on Amazon, I narrowed my search to this set of Lapasa Ultra Heavyweight Thermal Underwear. They come in a variety of colors, and I chose the Navy-Blue set. The first time I wore them I knew I found the right set. Not only are they very comfortable, but they are well insulated, warm and stretchy enough to perform physical activities in extremely cold environments. I wear size large for most clothing items, so I ordered a large set and they fit perfectly. Since this is an ultra-heavyweight set of underwear, they are probably too warm and thick for milder temperatures and physical activities but are very appropriate for extreme cold temperatures. Overall, they are a little pricey but well worth the investment. I’m very pleased with my Lapasa Ultra Heavyweight Thermal Underwear Set and recommend them to anyone searching for a high quality and comfortable set of extreme cold weather underwear. ... show more

  • Pants slide down
The waist on the pants doesn't keep them up very well. They are cotton sweats with fleece lining. Not what I was expecting. I missed that they are cotton in the description. Don't wear cotton in the snow.
