  • 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

  • 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

  • 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

  • great fit and fabric
this was exactly as described. Fleece lined, and soft exterior material. The fit was perfect for two XL. Highly recommend.

  • Cold days are bearable now
Special Size Type: Thermoflux 100 Lightweight Size: X-Large Color: Black
I have used the thermal under garments under my clothes when riding my motorcycle. 49° outside, and I was very comfortable. I ordered large, and the fit was a bit loose. 😅 Very happy with the product.

I bought them because I get cold very easily. these keep me warm, and I hardly know I have them on. This is a very good purchase.

  • Best budget thermals on the market.
The fit, size, stretch, warmth and moisture wicking are all near perfect. Are there brands like Under Armour that perform a little better? Sure, but I was able to buy a medium AND heavyweight set of Lapasa for less than a single set of more expensive thermals. Bottom line: This company knows their business. ... show more
