LAPASA Men's Thermal Underwear Set Soft Fleece Lined Long Johns Light/Mid/Heavy Weight Base Layer Top & Bottom M11/M24/M57

I love this set. I work in construction and love the outdoors so I'm constantly wearing them. Besides normal pilling from washing i find this set very durable. They fit well according to the sizing chart and haven't shrunk after many many washes. I will continue to buy.

First, let me say that, while I ordered a medium, a large with shipped to me. Rather than go through the return, refund and reorder process, I decided to try contacting LAPASA first. A representative replied to my message in the same day, offering to send the correct size straight away or refund the product immediately. The representative, who did supply her name, did not request that I leave positive feedback (or any feedback at all) as a stipulation to receive her assistance. She just acknowledged the problem, offered the solutions and did it in a friendly manner. I chose a replacement. Great communication and resolution. As stated, my info is 195lbs / 6'0" / Size: Medium. I originally ordered the large and it was too loose on me/didn't hug my skin. The mediums fit perfect. I have long arms and legs with a short torso. Even so, the length of both the top and the bottom is good. Although I haven't worn these in very cold weather, the thickness and quality of the outer material is very good. Added to that, the fleece inner material is substantial & soft. These thermals should perform very well in cold weather. Indeed, they do seem to be heavyweight as promised. I will update after testing them in said conditions. For my preference, the thermal shirt could be longer in terms of body length. But it does have sufficient length to be tucked in. I believe this product to be a fantastic buy and my update will be posted very soon, as the weather has just turned, heading towards bitter cold. (I've included two images of the inside fleece material in an attempt to illustrate the thickness and quality. Otherwise, the set looks exactly the same as pictured.)

My husband loves these. they are so comfortable, and warm, he works outside all day and a lot of nights. He now has 8 pairs and wants more for backups.

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.

Super warm. Thick fleece thermals. Not good for heavy activity, you will sweat. Perfect for light activity and sitting. Wore them in -5 f and plenty warm. Too warm for snow skiing though. Deer hunting yes

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.

I'm in Fairbanks Alaska, and purchased the thermoflux 300 in size Large, I love these as a 'base layer' when I have to go out in the extreme cold such as -30. Again, as a 'base layer' they are very warm under insulated clothing. Here it's all about layering. I have actually worn these under my jeans or insulated sweat pants when I go shopping and they never fail to keep me warm. I'm here because I'm thinking of ordering another pair and had to look up my order history to easily find them and thought I'd leave a comment.

I ordered the heavier version and I was worry it would be too thick and not flexible enough, but it is! It’s really comfortable to wear and very well made
