Terramar Men's Thermasilk Crew Neck Top

I have 3 so far I love these so much. I want to buy even more. They make a great underlayer, adding a surprising amount of warmth, for minimal weight and bulk. You'll forget you have them on. They feel super good against my skin. Unlike things like polypro underwear, I don't overheat and sweat in these. I wear them to bed, underneath other layers when hiking, and whenever I want an extra layer of warmth. They are very thin, and you might think they will be flimsy and not last... not at all the case, at least in my experience. They keep their shape too. I've put them through some tough trials too. I have yet to have one wear out on me. I send them through the washer and dryer with everything else. I bought both the men's and women's versions (same brand). In men's I need a size smaller that what I take in women's. The design is different, and the fabric used for the men's (this product) is thicker and a different knit pattern. I like the men's much, much better. So although the women's has held up just as well, I won't replace them. I'll just buy more of the men's design.

These things are great, and I don't understand any criticism on how they wear.These are not meant to be the only under layer for anyone who is active. They are silk, which is very strong, but on the other hand, they are silk, which is always very thin. I've worn and washed mine several times now with no stretching, no running and no snags. I put them in a bag before I add them to the laundry. I got that tip from another reviewer, and it may be why they are still perfect.For an old guy like me who just wants a little extra warmth when I walk my dog, weed my garden, or lock myself out of my house, these are fine as my only under layer. For a bricklayer, a cowboy, a lineman, or a more active person, you might be better off with regular long johns as your first under layer and add these when it gets colder.Some comments talk about lack of warmth, but you will only get a little more warmth (they are really thin) when there is no wind (they are really thin.) (It bears repeating.) If your top layer is windproof, you will notice the extra warmth even in a wind. If your top layer is not windproof, don't expect the wind to be slowed down with this top. It's not made for that purpose. But on a still day, you can definitely tell a difference in warmth when you wear these with any outer layer.So no great warmth and no protection from the wind. Where is the benefit? This is your bottom layer. It pulls the sweat from your body and keeps you dry. That is its main job, and it does it well. The extra warmth is just a bonus. On the coldest of days, I'll have my silkies, my long johns, a heavy shirt, a coat, and a vest. The silkies are just there to keep me dry. The other layers keep me warm.Another bonus for me is that wearing these to bed does not feel constrictive. They are very light and they are stretchy. I normally don't wear anything to bed because I hate when you turn over and your clothes bind and you have to readjust. With these, I wear them to bed and don't notice them.I'll be buying these until they stop selling them.

I give it 4 stars, but only because I bought it "off season" when the price was *much* lower than it's been since mid-Fall. (That may explain the discrepancy between some of the reviews, too, since most reviewers don't mention what they paid for it.) Mine was about ten bucks, in mid-September. It's easily worth that price. I bought one to try and left the item in the "Saved for Later" part of Amazon's shopping cart to buy more if I liked it, but by the time I'd thought to order more, the price had shot WAY up. (The same thing was true for the glove liners I bought, and the long johns I unfortunately did not buy the first time around.)As always, silk is *much* warmer than cotton and warmer than most wool, but that's as measured *by weight*. This undershirt is warmer than a currently-common thin cotton undershirt, but no warmer than a heavier cotton T-shirt. But is IS much thinner and more comfortable. I especially like wearing it under a thinner pullover, where it provides adequate protection (for both my skin and the sweater) and a little extra warmth without visible bulk. (I do wish they made them with a V-neck, though, since the collar is a tad high and tends to show around the neck of many of my sweaters.) The wrist cuffs are a bit on the loose side, but that's pretty typical of pure silk and I've always found this a common problem with long-sleeved silk undershirts, the fiber just isn't as springy as cotton and some types of wool. A little lycra in the cuffs would be nice, but seriously, I wouldn't expect that sort of touch in anything but a very expensive shirt - WIntersilks don't have it either. But at full price ($20s), I won't be buying more. (If/when prices go back down next Spring, I will stock up, however.)I don't own any recent-vintage Wintersilks, so I don't know how they're making *them* these days - the few pieces I have are all more than 20 years old. (Living in NYC where it very rarely gets "bitterly" cold, I just don't have all that much use for them, though I have worn them regularly, if not frequently, every Winter for all that time.) To be fair, not all of my Wintersilks have surived that long, but a few have, and I don't take special care of them. They go in the warm/color wash and get dried in the drier. I very seriously doubt, on the other hand, that this shirt will last 5 years, much less 20. And since I can't be bothered with things like "lingerie bags" for the washer, am very unlikely to risk putting these through a regular wash cycle along with my other clothes. The fabric isn't terrible. It's not so much that the yarn seems much thinner than other silk undergarments', but the knit is definitely looser.

Does its job fairly well. It doesn't add quite as much warmth as I was hoping; about as much as you would get from putting a t-shirt under whatever else you're wearing. Of course, it's a thin silk thermal shirt, so it's not meant to give that much added warmth. And if the wind is blowing and you don't have a jacket or something to block it, this won't help at all.However, it does provide some warmth and is very comfortable. It also doesn't collect body odor like a cotton t-shirt would, and it's very easy and simple to clean. I've rinsed it out in the bathroom sink in the evening before going to bed, hung it on a hanger or over a door, and it's completely dry by morning, ready for another day of silky warmth.

very lightweight useful underlayer

My husband is 5’11” and 140lbs approx, he usually wears size S for everything as he is quite lean, I bought a S based on the size chart. The silk undershirt is sheer as expected, but the shirt has “raglan” shoulder, not a regular shoulder like the picture. Hubby tried it on before wash, the size is really quite small, difficult to put on, and taking it off is a challenge. After one quick wash in the machine (with a laundry bag) with cold water and hang dry, it’s now a woman’s size XS and it fits nicely snug on me, NOT him. I wouldn’t mind buying another one but I would go up at least a size (or even two sizes!) just to allow shrinkage. I mean even if it is a bit too big after shrinking and fits loose instead of snug, it’s so thin that it would not bulk up your sweater or shirt on top (you must wear something on top, wearing this silk layer alone will make you look like a ballet dancer). He has an older silk undershirt also from Terramar like 10 years ago and that did not shrink like this new piece. Just like anything silk, you want to be gentle with it, not pulling it too hard so you don’t rip the seams because its sheer like pantyhose. I am giving it 3 stars because of the shrinkage issue.

Don’t wash it. Poor material. Picks up lint and the weave of the material is separating causing it to look old already. Thread pulling. It’s silk however and it does keep u warm. I bought 5 so I nvested a lot at 60$ Cdn for one. Gave one to each of my family members based on the quality of one I bought 8 years ago and still wear - shredding. They don’t make them like they used to.Would not buy anymore.

Muy recomendable para climas frios

I put 2 stars because very comfy, but got a big hole in it on day 2. I dont know if I was just unlucky or if its the make of it but the durability just isnt worth it. Also Very see through..

Great base layer, handles moisture well.However, shirt is see-through..!Don't plan on wearing this without another shirt over top.

At work I am in and out all day, cotton would get damp then I would freeze outside, but these new silk tops worked well to wick away moisture.

Perfect thin extra layer.
