Color: Dark Grey Size: Large
Best thermal underwater ever! Very well made! Heavy duty warmth! Has like a fuzzy flannel inside! Ordering more as gifts! Seem to run one size smaller, so if you need a Large order an extra Large! Great Product!

  • They are thick!
Color: Heather Gray Size: Large
First, as the headline says, they are THICK. I've read many times that it feels like a thick wetsuit, and I would say that is close. I would also describe it as a thick, tight fitting sweatshirt. Warmth - It's strange...considering their thickness, they certainly SHOULD be warm AND THEY ARE. But for the thickness, I would have thought they'd be even warmer. I really don't think you'll be disappointed in the warmth, but if you are expecting perfect warmth, they don't quite get there. Moisture Wicking - They are warm and in fact, I found myself sweating while shoveling snow, in cold temperatures. As far as moisture wicking, in my experience so far, it doesn't wick moisture very well. By the time I got in the house, I was sweating enough that I had trouble getting them off. They were "sticky" from holding in moisture. Fit - In my opinion, they run small. They are a base layer, so you can expect them to "hug" you. They are not sweats, although they feel thick, like that. I am 6-1, 190 lbs. I ordered the Large. When you order Large, you get both the top and bottom in large. I've gotten skinnier legs, so there is no way I could wear an XL for bottoms. But I could maybe use an XL in a top. So that is something to consider. Might be nice if you could order a different size top and bottom. I have trouble removing the top. It is thick, it is tight and if you are sweating at all...it gets sticky. But remember, it is a base layer and fits a little like the compression tight fitting base layers, but extremely thick. It's thicker than UA 4.0. It's cheaper than UA 4.0. But I'm not convinced it performs better than UA 4.0. One more thing...because of the thickness if you are wearing anything over them, it will need to be a little larger outer garment. In particular, pants could be an issue if you are wearing these underneath again simply because they are so thick. ... show more

  • You know those glasses cleaning cloths? It's like that but thicker
Much thicker at that. I received these before I had to head off to work, which was quite awesome because I didn't have to work in the outdoors for the 12 hour shift thinking of fire-places and heaters all day in the sub-zero weather. When I first put them on, they felt a bit snug, but these are a base layer, so it was to be expected, but as thick as these are compared to my waffle knit, it was something I had to get used to. I was noticing them for quite some time during my shift, but eventually grew numb to the feeling of being hugged by spandex. I felt like I was wearing a dive suit, but with a soft lining interior and fabric exterior. For the performance, they performed quite well, not quite the 3 layers of fleece blanketing next to the radiator that I was hoping for, but far exceeded wearing 2 sets of waffle knits just to put off the cold a bit longer. As I stood outside, I felt as if I should have been sipping on something from a mug clasped with both hands, but I don't really think a man should ever hold a mug with both hands ever, so I held mine with just the one. I stood outside for a good 2 hours without working up a shiver, and never even came close, I felt like i could go another 10 hours or more. I would say after 20-30 minutes, if you're not shivering, you're never going to, unless the wind is blowing... really... really... hard, or you're skydiving, which neither of those things were happening, a few gusts here and there, but these didn't break a sweat. Speaking of sweat, they do not get you really hot either, they do a fantastic job at regulating your body temperature, unless you're sitting in a heated cab, they aren't going to bake you. Some additional thoughts. I'm not going to remove a star over this, because everyone has a different shape and size. I went by the sizing guideline, and I was right there at the line of L and XL, me being 6'1" and 185lbs, my gut told me XL, but logic and research said L. I went with L. while the pants and main shirt area are just the right size, the sleeves seem to ride up my arms a bit. It feels like the sleeves came off a medium shirt while the rest were stitched as large. I have received comments on my rather long arms in the past, so it's definitely my body's problem, because for some reason, I've been given XL arms for my regular L body. If anyone want's to trade arms, let me know. ... show more

  • When you need sub-zero base layer protection
Color: Dark Grey Size: Small
I rarely write reviews of any substance but this company knows how to do base layer clothing. I live along the Canadian border in the Midwest and we have some brutal winters because of wind chill and the lake effects in my area. That translates into a significant portion of the winter in subzero temps. Usually several -50f days at its coldest. I've worn a bunch of different base layers and all of them promise to keep you warm and dry and a host of other gimmicky claims. Outside of some high end expedition gear companies, none of them have hit the mark. Either too thin, too thick, wrong mix of materials, etc, etc. Well, these are the price range holy grail for me. And they should be for you too. That material just feels like you are sliding into snug well fitted Chinchilla. If you have ever pet one, then imagine wearing that same experience all over. Its quite pleasant to say the least. Very warm without baking you in your own juices and defeating its purpose in creating sweat which may then cool you down as it chills. Seems to wick very well surprisingly considering how thick the material is. It is very nice not to have to wear 3 layers, a soft shell, and and overcoat now just to be comfortable. When its miserable outside, I use this base layer, then either my soft shell or over coat. But so far I haven't had to use all 3. Between, this and this companies heavyweight base layers you cannot go wrong in grabbing a few sets. They are extremely well stitched so I expect them to last many seasons without issue. Grab a set yourself and you'll see what I mean. ... show more
