This is The North Face Expedition Zip-Neck long-sleeve top, women's small. The color is not quite right in the pictures. It's a dark blue with a hint of purple. The pictures are more blue than in reality.
I've worn this top multiple times, but it still looks close to new. I'm really impressed. There's no pilling (like Smartwool tops), no snags, and the logos are still perfect. I just looked up reviews online and several people complained about the zipper being scratchy, but I've never noticed that.
It's warm and it fits like a baselayer. I'm 5'8" and 125 pounds and fits me perfectly. If you're familiar with Smartwool "weights" it's thicker than the Smartwool 250. I'm selling because I haven't worn it in a while and I've been opting for my Smartwool shirts instead.
Here's the description from The North Face's website:
