  • Very nice
Hard core outside guy, live in Maine, work marine construction year round. I hate being cold, and bought these while at work. These things are ridiculously warm. Almost to warm for working in if you are acclimated to the cold. Very comfortable, seem to be a good fit for the size and feel like they are decently put together. I am 6’, 220, average guy and the XL fits perfectly. ... show more

  • Comfortable, well constructed, great value
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

  • Soft, warm, snug and true to size. Solid purchase!
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

  • These thermal Long Johns really work
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. ... show more

  • Nice Long John’s
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

  • Soft and warm
I bought these for my husband because he works outside in the wintertime and I told him to try them and he loves them they are soft and kept him warm and let him move freely without being uncomfortable with them riding up like others that he has had in the past.

  • Great purchase!!
Purchased for our son. Wears under his pants as he works outside. He loves them. Says they fit perfectly and feel super comfortable. He barely knows they are on. We have actually purchased multiple pairs. Highly recommend.

  • The inseam is 26" for sure.... wicked short. Really bummed about that.
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
