  • Comfy and warm
Size: X-Large Color: Grey
These thermals are the perfect addition, to my outdoor work uniform. They keep me warm, and are very comfortable.

  • Really comfortable
Size: X-Large Color: Charcoal
I'm 6 ft 220lbs and wear 36-38 waist. I ordered XL and they are snug, just how long underwear should be. I've never paid this much for long johns before, but they're worth it. The inside is fleece lined making them the most comfortable I've ever worn. The only downside is because of the type of material they're made from, they get those little lint balls on them. They're more expensive than other brands, but I'll be buying more of them because of how comfortable and warm they are. ... show more

  • Worth the price. But wait.. there's more.
Size: 3X-Large Color: Black
Hey potential buyer! I just wanted to drop by and tell you that these thermals are absolutely worth the cost! But before you make your decision, there are a few things you should know. Firstly, they appear to be a 2-layer thing. The inside is made of a softer fleece-like material compared to the outer layer. This is important because it might affect how you clean them. So, make sure to follow the care instructions to keep them in top shape! Secondly, while these thermals are incredibly warm and work wonders, they aren't truly wind resistant. I just wanted to be honest about that because I believe in transparency. But trust me, they'll still keep you cozy on those chilly days! Lastly, these thermals fit snug. So, if you prefer a more relaxed fit, I recommend going a size up. It's always better to be comfortable, right? ... show more

  • Warm and cozy
Size: Medium Color: Navy
Great to wear as pajamas or as long John’s to stay extra warm when it’s cold outside. Fabric has a lot of give in it for a great fit, but never gets baggy or out of shape.

  • bought a second set immediately
Size: X-Large Color: Black
i can no longer buy my preferred union suit (from another vendor), so i took a chance on these. they're incredibly soft and fit well (i'm about 5 foot 7 inches and 200 lbs, most of it belly) and they certainly keep me warm. the only downside is that they want to be washed in cold water, but i can forgive that. i was so impressed that i bought a second set so i have something to wear while the first set is in the wash. hey, it's cold here! ... show more

  • For great and warm!
Size: Large Color: Black
5’10” 160 and these fit me great. Room to grow too if you know what I mean. 😂. Was a little worried about the length when I pulled them out of the package but when I put them on, it was obvious that wasn’t going to be an issue. They keep me nice and warm but not too warm and very comfortable.

  • Good while they lasted...
Size: XX-Large Color: Grey
They were soft to the skin and warm. The dislike, they lasted two seasons...I had other long underwear last ten years! Not made to last.
