These thermals are wonderful. They fit well under clothes. Easy to move in, the material is very soft and comfortable. The level of warmth they have is great, Wearing these you will not be disappointed while in the cold. I have bought more because they are great quality.

I am always cold. If the temperature is below 60F, I start having difficulty regulating my body temperature. I have spent more money on various "warmest rating" outerwear and base layers than I care to think about and nothing seemed to cut the cold of midwest winters...until these. I was so impressed with the performance of these that I now own four sets of the thickest/warmest ones as well as two of the mid-weight shirts for when I need a bit of added warmth but not a full set of base layers. I spent 16 hours insulating an attic while it was 19 degrees outside in just these with a sweatshirt and pants over them and I was never cold at ALL. They're also great for doing outdoor winter projects. Sizing/fit: Across the four sets that I now own, there is some slight size variation but not enough that I would order anything but my usual size. The navy blue set runs a tad short/small but it works just fine. I believe these generally fit very true to size. These have a lot of stretch for ease of movement and don't fit as snug as many base layers do. I like that. If you're on the fence about size, unsure whether to buy your usual size or size up, I would suggest your usual size. Bottom line: if you're on the fence and wondering if this will just be another base layer than makes promises it can't keep, these actually do the job and do it well. GET THEM.

When I first opened the box I was surprised to see a nicely packaged product that gave it a real premium feel. The underwear is EXTREMELY comfortable and from the moment I put them on I could feel the extra warmth. The day I bought them I went for a walk with my family and it was about 50 degrees out. I didn't feel like wearing a jacket so I just wore the long underwear under a sweatshirt and jogging pants. I felt very comfortable and the underwear didn't make me too warm. The material is extremely light and soft. It felt like I wasn't even wearing it. The only thing that's preventing a 5 star rating is that the bottoms have a little too much give in the waistband. I'm 5'10" and 180lbs and ordered a large. The top fits nice, but I may end up returning them for a M. I also don't know if they will be good for subzero weather. I'll have to wait to winter to find out.

Living in the south and working indoors, I haven't had a chance to wear these a lot. But when I have, I've been very pleased with the purchase. Unlike old school "waffle" long johns, these have a fleece lining that makes them extremely comfortable against the skin and the heavyweight version lives up to the name, I'd say. I've warn these as a base layer in 25F weather and stayed more or less comfortable. I'd say they run slightly large. If you want a tight fit for your base layer, you *may* want to consider ordering a size down. However, I didn't feel it was necessary as my cold weather outer layers are a little baggier as well.

Super warm and perfect fitting. Bought for snowboarding and they have been almost too warm thankfully they are breathable. The fabric lining is super soft and durable and the stretchy outer makes then easy to put on but super functional and fitting. They look like super expensive pairs and don’t hold smell.

Needed some thermals for snowmobiling. I am not writing this for Amazon, but writing it for my fellow snowmobilers. Very few reviews I have found for thermals talk about sledding, so here you are. I have tried several and I love these. I don't need to look any further now that I have used them. These are very warm and comfortable. I am 6' 1", 225lb with more dad bod than chiseled bod. I bought XL and like the fit, snug but not stupid tight. I don't feel restricted and forget I have them on. Five below zero with one layer of clothes over, plus my snowmobile bib and jacket, and I was toasty warm at pretty high speed. I tend to go when it is extremely cold, and I am 100% satisfied with these. I would not hesitate to go out at -20 with these as my base layer. After using the heavy weightI added a medium weight set for spring riding. I wore the medium weight on a day that started cold and ended up over 35 degrees and I was uncomfortably warm, felt like I was sweating a lot (drank 4 bottles of water that day) - They performed as promised as I never got soaked in sweat - they really do wick away the moisture - open coat and bibs and stayed dry. I was looking for reviews that addressed these issues for snowmobiler and didn't find much, so here you go, hope this is helpful. I think you can buy these with confidence.

These are terrifically comfortable as well as effective. Right now I’m wearing only these in a 68F (20C) house in perfect comfort. I added a sweatshirt but found the combo too warm. The fit is exactly as expected. What wasn’t expected but welcome is that they are both warm as well as being smooth (as opposed to the waffle material) and thin yet warm. In a severe test, I wore these as a first layer under Carhartt overalls, a light sweatshirt and a snowmobile jacket for motorcycle riding. Starting in temperatures of about 38F or 3C I was comfortable up to speeds of 80 mph or 130 kms/hr in a naked (no fairing or windshield) bike. If you choose to wear this and are male, I strongly suggest you do not use underwear under these. Doing so will leave you in a difficult position to relieve yourself. I’m pleased with all aspects of these finding them to be more comfortable and effective than I thought when I ordered them. Definitely a winner.
