  • Best thermals I've ever had
Size: Large Style: Crewneck Color: Black
I can't recommend this brand enough! Our whole family has been really impressed. The fit is true to size, and the material is super soft, making it comfortable for all-day wear. These thermals keep us warm without making us sweat, which is perfect for our activities like hunting, snow machining, trapping sledding etc. Durability is another great thing about them. After many wears and washes, they still look and feel new. We won’t buy thermal clothing from anyone else. They offer the perfect combination of comfort, warmth with affordability, and I highly recommend them for anyone who needs reliable fall winter and spring gear ... show more

  • Perfect Fit, love the material
Size: Large Style: Crewneck Color: Hunter Green
Just got these as I am going to Greenland on a cruise. Tried them on and they fit me perfect and are comfortable. The material is very soft and feels nice. Will update on how they worked in the colder air. I am 5 feet 5 inches, 185lbs and the large was a perfect fit for me. UPDATE: Did a great job keeping me warm on an excursion in Nuuk, Greenland on an open boat at 38 degrees. Fit well and very comfy without being bulky. ... show more

  • Worked Great
Size: X-Large Style: Crewneck Color: Black
My husband liked these longjohns. They kept the cold freezing air off his body. He felt very comfortable while wearing them under his clothing when we were in frigid temperatures.

  • Nice thermals
Size: Large Style: Crewneck Color: Black
I like the pants a lot as they are thin but warm and smooth not rough or waffled like many others. Fit was on point for the pants and I am 5'8" 163lbs. Shirt while smooth and very comfortable is a bit tighter fit than the pants. Hope to street it out a bit, but it has a thin low profile to layer, could just use a tad more room. I have a 42" chest. ... show more

  • So comfy
Size: X-Large Style: Crewneck Color: Black
Very comfortable. They don’t ride up! I use them as pajamas as they are very warm and stretchy making them very nice and comfortable. The color matched the description. I’ve been wearing the regularly and no pilling at all. Very good value for the money.

  • Necessary while cold weather riding
Size: Medium Style: Crewneck Color: Navy
These are perfect for when my guy and I are riding motorcycles during colder weather. Felt comfortable under our clothing and kept us really warm without bundling up too much!

  • Good price for what it is - the white ones run small
Size: Small Style: Crewneck Color: Black
I bought one black pair originally. I’m 5’6 and around 150lbs. The small size fit me really well even with having a broader chest than the size chart indicated. I use these for staying a bit warmer around the house during the winter and they work well for that, I can def tell a difference. I ordered 4 more pairs so I wouldn’t have to wash them as frequently. I noticed that the black and blue fit me nicely while the white runs a tad small. They still fit but just a little snug and I’d probably order a size up in that color. Overall, these are a great buy especially when on sale. They are at the upper end of quality for this price range. I ordered some more expensive ones that work better for going outside in colder temps but ya get what ya pay for. ... show more
