Christy wrote a review of Patagonia Capilene 2 Lightweight Zip-Neck Shirt - Long-Sleeve - Women's on April 25, 2011
I bought this shirt in blue, and orange and red.
I ordered a small. This is pretty true to size.
I like this shirt because it is slender but does not ride up and show my stomach. It is extremely comfortable. The orange and red color is a bit bright but I wear it for hiking. However, I wear the blue often to work.I highly recommend
