  • This photo is not this item!
Special Size Type: Thermoflux 300 Heavyweight Size: Large Color: Dark Red
After seeing this photo, this is what I was expecting. My fault, I neglected to read the entire 12 paragraph review where the reviewer stated "item for comparison". Photos of other items should be prohibited in reviews, as they are easily mistaken for actual item. That said, I give the long johns a 5 star review. Very warm, super comfortable, neck/sleves and wrists well tailored. Waist while wel made, thin which I like, was a bit big. If you're not concerned with color, you can purchase shirt and pants separately so they are sized correctly for your body. And if you shop the sales you can save some money. I will buy these again. ... show more

  • Great customer service, Great quality, High hopes!
Special Size Type: Thermoflux 300 Heavyweight Size: Medium Color: Olive Green
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.) ... show more

  • Warmest Base Layer Ever
Special Size Type: Thermoflux 300 Heavyweight Size: Medium Color: Heather Blue
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. ... show more

  • Warm and cozy
Special Size Type: Thermoflux 300 Heavyweight Size: Large Color: White
This is a great product. The only reason I give 4 stars is because I wish they would make the white thermal tops with a v neck so that it wouldn't show under a button down shirt. A v neck version with half sleeves would be great! Still, I recommend this product highly. Both my husband and myself have many of Lapasa thermals and are very happy with them. We will continue to purchase them. ... show more

  • So comfortable
Special Size Type: Thermoflux 300 Heavyweight Size: Medium Color: White
I got 3 pair of these. As soon as I opened the first pair I was impressed and knew rifgt away they would be warm and comfortable. I don't know how long they will last but I assume they should be durable as even cheap thermals I bought years ago are still fine. These fit great. And look very nice and kept me warm outside in about 40-50 degrees (F). I will probably buy another few pair so I can use them everyday during the winter months. I got the heaviest weight (thermo flux). I am very happy. ... show more

  • Best Thermals for the Price - Make sure product ships directly from Amazon and not the manufacturer!
Special Size Type: Thermoflux 300 Heavyweight Size: Large Color: Black
These thermals are amazing. The thickness keeps me warm in really cold weather and have no issue going out in conditions below freezing if I am wearing the 300 heavyweight set. However, make sure you only buy this brand if it comes directly from Amazon. The Amazon shipment comes with the high quality you expect from this brand, but if it comes directly from China they will send the wrong size, it doesn't fit as well and it will be challenging to try to return. You can get this set usually for around $30 price point, making it a great value for the money. But if you order it and the manufacturer shows shipped and sold from boxinhong US- it is being shipped from China, takes up to month, and likely there will be issues. Why I am emphasizing this is I bought three sets for 100 and it came from China, I ordered Large and it came 5XL, and finally Amazon refunded me for what I paid when the shipper failed to send the return label. But every time I have ordered an additional set that has shipped from Amazon I got the correct size and the quality that I expected. ... show more
