Smartwool Women's NTS Microweight Crew

My new favorite
I love this micro-weight layer. It is the perfect layering for work and at home when you just need a little extra warmth. Very comfortable! I love the smartwool brand and have used the baselayers for skiing & other winter sports, but they are a bit too warm for everyday stuff. This micro-weight is the perfect solution for those chilly days when you are not outside.

Great baselayer, comfortable and attractive, too!
This is another quality made Smartwool product. I've worn this as a baselayer and I'm amazed just how comfortable it is, adds warmth without ever making me feel hot. I love to sleep in it, too. In fact, on my next winter overnight I plan to wear this and a lightweight bottom in my sleeping bag. I learned the hard way that less is more is the trick for staying warm in your sleeping bag when it's cold. This should do the trick. I have this in peony, size Medium and it fits really well. I had to return the Large because it was just too big. I'm 5'3, 135, bust is about 36, so I guess it fits just right. Just a nitpick, but being short, arm length is almost always too long, but I just move the sleeves around and it works out okay. If you have long or "normal" length arms this should fit perfectly.

soft and feminine
I got this to wear under light sweaters/shirts in the spring and fall. I have been wearing it lately in spring, in Colorado, and it is a perfect weight/warmth in cooler days. It is cut long, which I love as I am fairly tall-5'8", you can tuck it in and it will stay in. It is very soft and not at all itchy, and I have sensitive skin. I love the color-vibrant, yet feminine. I have also worn it on it's own, as it is pretty to look at-it doesn't look like 'long underwear'. The only downside is it was fairly expensive. I have quite a few Smartwool clothes and love them all-they last very well and always have great colors and are well cut, so feel they are a good investment.
