  • Shirt is Superb and Pants are Great
Size: X-Large Color: Charcoal
I bought an XL for this set and am heavily satisfied with these products, especially the top. To me, it's an all-around long sleeve shirt that I can wear outdoors without it looking like my normal PJs. It's comfy as hell and warm as a fluffy duck. Works perfectly in Seattle weather and just absolutely perfect. As for the pants, all I'm gonna say is that the pants might be tight on you so just be wary of that. Mind you, the pants are not uncomfortable in any way. They're great, comfy, and has thermal mechanics, for sure. It's just a little tight, so be mindful of that. All in all, great, comfy set and, if ever, buy it for the shirt. ... show more

  • Great purchase for the price !
Size: Medium Color: Black
I bought this set for my son who works outside and he told me that this was the best buy for his line of work, it kept him more than warm in 28 degree weather in PA . Next purchase is a size up ..he is 5'8 140 lbs and it just fits him ,it fits snug and comfortable. Great purchase for the price !

  • True to size. Yes, the pants have a fly.
Size: Medium Color: White
A decent set of stretchy thermal underwear. Fits true to size. My only complaint would be that the pants do in fact come with a fly, and I prefer this type of "base layer" not have that. I asked Amazon's AI help about this before purchase, and they assured me there was no fly, so beware. Aside from that, they are a good base layer, and well priced. ... show more

  • Soft and stretchy and don't pill!
Size: Large Color: Black
These might be the most comfortable things I've ever put on my body! I've bought other brands that feel tight like compression leggings, but these are soft and stretchy. They also don't pill when you wash them. I have 3 colors purchased over three years.

  • Size XXL thermal underwear (SIZE UP!)
Size: XX-Large Color: Black
Overall a great product for under $20. The reviews were VERY helpful. Everyone said to size up , as they run small. 100% true !! Had I not read the reviews , I would have had to exchange for a bigger size for my husband. He wears an XL , but I purchased a XXL, and they fit perfect . He works outside every day , and he said they are very warm and comfortable ! Would absolutely purchase again. ... show more

  • Great top, small bottoms
Size: Medium Color: Black
Bought for my boyfriend for a ski trip. The top was perfect but the pants were very small. My boyfriend couldn’t fit in them and we ordered his normal size. The top worked well for the price, but beware the pants are almost unusable.

  • Very comfortable, lightweight and warm
Size: XX-Large Color: Charcoal
The fabric on these long johns is silky smooth on the outside and has a very soft, short fleece on the inside. They are very comfortable and feel good. The fit is snug, but the fabric is very stretchy. I ordered a size up as suggested in the description for a better fit and was happy I did. The shirt tail is nice and long which was unexpected and a really nice feature. I liked this enough to buy a second pair. ... show more

  • Best Thermal Long John Underwear Ever.
Size: Medium Color: Navy
I had a set of these, but I couldn't find the maker's name anyware on them. They just had washing instructions on the labels. These looked very much like the ones I had, and when I got them, they were exactly the same as the ones I had, except they did have a name, DEVOPS, on the tags. They are great! They fit perfectly, and keep me very warm when I go running out in cold termperatures. The top is simple and the pants don't have those stupid fly like things. The pants also don't have a seem splitting the front. They have kind of a pouch like front. I wash them using cold water in the sink and let them air dry. ... show more
