This is an excellent product. The material has just the right feel and weight to it -- not too thick or thin, not too hot or cool, stretchy but not overly so. The garment appears to be well constructed; the stitching is flawless as far as I can tell. I'm 5'9" 165 lbs and size medium fits perfectly. Extremely comfortable and the price is definitely right. Highly recommended.

As a postal carrier who spends long hours outdoors, I recently tried out the Thermajohn Long Johns for Men, and they have truly exceeded my expectations. The fit is true to size and extremely comfortable, thanks to the soft fabric blend. The material is stretchy yet snug, providing a second-skin feel without feeling restrictive. I wore them all day during my rounds, and they didn't bunch up or chafe, which is a significant plus for someone who is constantly on the move

I really like this as a base layer. It’s nice and soft, and the fit isn’t too bad. It’s a tad bit loose around the waist and since there’s no draw string to tighten it, it slides a little throughout the day. The only real reason I give it a 4/5 starts is because not even a full day went by before the inside seam stitch came apart and left a hole near the middle of my thigh.

I am VERY happy with these Thermal Long Johns, they really work. They do EXACTLY what they say they will do, namely keeping your legs warm in cold weather. I wear them when I go for my exercise walk and they work great. I wear them under my sweat pants in the cold weather and they work great. They are made of high quality material and are very light and very comfortable--I have ZERO complaints. I got my moneys worth.

I got these for my grandson for when he’s at work. He’s unloading UPS trucks all day in this cold weather. I asked him what he thought about the long John’s. He said they are the best and most comfortable long John’s he’s ever worn and the only kind he will buy from now on. He likes to work in jogging pants. He said these long John’s keep the cold air away from his legs. I’m going to get him a few more pairs if they mark them down again. I’m not going to pay $20.00 for them. I just feel like they are over priced. But that’s just me. I’ve washed this pair for him every other night since November. That’s two months. They still look as they did the day we received them. So you can feel safe about throwing them in the washer and dryer. I hope my review helped someone who’s considering purchasing them.

I'm about 5'8", 185 lbs. I wear a size 36-38 waist (closer to 38). I ordered a size Large. These thermal underwear have a "high tech" feel to them, they make me feel like an astronaut with access to premium space-age fabric. I say this because of how flexible the fabric seems to be, it kind of adjusts itself, molds itself, to my body. It fits me perfect at the waist, yet when I tug on the waistband, it easily stretches to where I think that I can probably gain 25-30 pounds and still be able to comfortable wear these leggings. Length-wise, the ankle bottom part has this same elastic trait, to where I think that somebody a few inches taller than me would fit into these leggings just fine. The stitching is uniform and looks strong, and they come with a printed on tag, which is convenient and eliminates discomfort or having to remove it yourself. The crotch area of the pants has reinforced stitching. See photos. These underwear seem like they will withstand accidental wear/use just fine. For example, I don't have to be worried about easily ripping them due to stretching too much, or snagging them on a cabinet knob. Despite the size/fitting guide suggesting that I order XL-2XL, Large fit me just fine with plenty of room to grow. I would recommend somebody up to about 5'10", 200lbs to go with the large, however, due so at your own discretion. Finally, referencing my uploaded photos, the sun was hitting these leggings, making them seem like they are lighter in color than they actually are. Have no fear, these leggins are jet black as advertised.

Perfect second layer for cold mornings on a motorcycle. The fit was excellent and it really snugs down at the ankles so it makes a nice layer that fits underneath my Motorcycle jeans.

Sizing up the guy... I fall into the Large size range. But purchased the medium. I'm glad I did too. My Waist is 33", Hips are 37", Thigh circumference are ~22", calves ~14" and my height is 5' 10" with a 33" inseam and ~160 lbs. Fitment: They hug just right! They are so soft and warm when sitting around in the house. The worst thing is the inseam is 26".... It's so short.... There is 4" of bare skin exposed to my ankles. What a bummer. I'm very sad about that. I wish they did a "tall" size or at least made them 31" inseam. You can kinda stretch them but that just makes them ride down. The material is thinner than expected, but meets the $18 price point compared to the UA Base 3.0. The fleece lining is soft and nice. It's not doubled lined but like small fuzzy soft. Not sure how durable they are, I've worn them once.
