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.

Perfect Baselayer
Smartwool's microweight crew is my "go-to" baselayer. It is very comfortable, not heavy or scratchy, and keeps me just the right temperature. The styling, fit and quality of the microweight crew is better than any other merino baselayer that I have tried. I wear it for skiing, snowshoeing and hiking, but it looks good enough to wear around town on the weekends. It is perfect for the cold, windy and foggy days in SF and night games at the ballpark.

Smartwool rocks!
I am a serious runner and this shirt makes me feel so much more comfortable then any other polyester shirt I used to wear before for years. Smartwool shirts wick away moisture quick and don't stink even after several times of wearing and sweating. I got also the lightweight and medium weight shirt for colder temperatures. Runs a bit small, you may want to size up. A must have for outdoor people!

Wow! Best long underwear ever!
I've worn smartwool socks for years, but I've never tried the long underwear. I'm so glad I did! This microweight top is so light I didn't feel it at all, but it really kept me warm during strenuous work in the cold. I was really sweaty when I came inside and took off my coat. The amazing thing is that I didn't get a chill, and I was completely dry within a few minutes. Also, no lingering smell. I'll try the bottoms next.

Best long underwear
I LOVE Smartwool - especially the microweight. Socks, tights, long sleeved tops and camisoles - they're all great. I'm going to order more Smartwool on Altrec as soon as I finish this review. The Smartwool machine washes and dries very quickly.
