  • Comfortable and warm but not fleece.
Color: Black Size: Medium
Pros: Very comfortable and warm in 30-40 degree weather. I was wearing a t-shirt and work pants over it; I got too hot with a jacket. 6'4" 150 lbs and it fit as expected. Cons: It is not fleece, its 90% polyester and 10% spandex. Feels a bit cheap compared to ThermaJohns which has a tighter feel.

  • Great fit and quality.
Color: Black Size: Large
Have ordered before. Product is great and doesn’t stretch out of shape. Easily worn under jeans in the cold north. Perfect product. Thank you.

  • What an amazing fit! Not sure how but they arrived in 6 hours as well. Mind Blown!
Color: Black Striped Size: Large
They fit very well, hug just right, aren't too warm and allow for full movement. I like that they cover well and are not see through. They have a soft fleece like lining that makes them beyond soft!!! They are perfect!

  • Great baselayer to wear under drysuit for kayaking
Color: Black Size: XX-Large
First, I'm 5'7", 250 lbs, 38-40 waist, 50 inch chest, XXL fits well and comfortable, though the sleeves and legs are a bit long. Not a big deal, they can be bunched up. The Fleece lining is very comfortable against my skin. I wear this under my drysuit. While in the water I found the sleeve of my drysuit had a leak. As the cold water came in, the sleeve of this base layer got pretty wet. The wet sleeve felt cold, but it still kept me fairly warm and didn't absorb much of the water, helping me to stay warm. The rest of me stayed comfortably warm in the 40° water, even though the drysuit itself didn't do much for warmth, it just kept me dry. **UPDATE** I have now worn this for three sessions of rolling practice in my kayak. I still have a small pinhole leak somewhere in the back panel of my drysuit, but it doesn't leak too much so I don't worry about it. This baselayer is still keeping me warm as the only thing I'm wearing under my drysuit in 45°f water, even when slightly damp. This isn't just while sitting inside the kayak, but also while submerged upside down and while swimming during a wet exit. This really is a great mid weight base layer, and one that any kayaker should consider for under their drysuit! If you're going to be in water any colder than this though, especially if the air temperatures are cold, I would recommend doubling up layers and either wearing a second set of these or getting a heavier layer to wear over them. Overall, this was a great buy and a much cheaper option than other base layers. I would definitely purchase this one again! -Piper's boyfriend :-) ... show more

  • Very comfortable and warm
Color: Navy Size: Large
Bought this set for a ski trip to Banff. It was not as cold as expected (25-35 degrees F average). But, these thermals kept me warm and I had no issues with them. I got two pairs of medium weight thermals. Both tops and bottoms. They are VERY soft and COMFORTABLE! My only issue was the size. I bought a large based on other customer reviews and a Large was too big. Not too big to use but a Medium would have been perfect. I am 5'8" tall and weigh 180 lbs. The bottoms were a little too long but I worked with that since I was skiing and could roll the extra length up without being bothered by it. The top fit better but it definitely wasn't fitted or snug like thermals should be. It did not fit like the picture of the model. Overall, very satisfied! Besides the fit (my bad for giving customer reviews too much credence), these are the best thermals I've owned. Which isn't a whole lot, but they really are very comfortable! ... show more
