  • Comfortable, well constructed, great value
Team Name: Classic Bottoms Size: Medium Color: Charcoal
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. ... show more

  • Great underware

Great fit. Warm and comfortable

  • Soft, warm, snug and true to size. Solid purchase!
Team Name: Classic Bottoms Size: Medium Color: Charcoal
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. ... show more

  • Nice Long John’s
Team Name: Classic Bottoms Size: Medium Color: Charcoal
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. ... show more

  • These are the best Thermal Underwear! Heavy duty, intended for very cold conditions.
Team Name: Branded Bottoms Size: Large Color: Charcoal
These are the best Thermal Underwear! Heavy duty, intended for very cold conditions. I have used LL bean, Dufold and others, these are the warmest. May be too warm for hiking or active conditions. I got the branded bottom. Inner lining is very soft. I like long underwear that is tight - typically I wear a large (38), these were a little tight but made them all the more effective. Enjoy ... show more

  • Great value
Team Name: Classic Bottoms Size: Medium Color: Charcoal
Wasn't expecting much for the price but gave it a shot based on reviews. Ended up being a great thermal base layer. It's definitely on the lighter side, but was actually exactly what I was looking for. Not too compressive, and fits perfectly. We'll see how it holds up over time, but seems like a great value. ... show more

  • So comfortable and warm.
Team Name: Branded Bottoms Size: X-Large Color: Navy
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 ... show more

  • The inseam is 26" for sure.... wicked short. Really bummed about that.
Team Name: Classic Bottoms Size: Medium Color: Black
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. ... show more
