I love these shirts!! I've worn the predecessor of this shirt [the silk weight] for years. Not only is it environmentally friendly, but is stylish, comfortable and quick drying making it perfect for exercise or for travel. It is great in winter because it wicks well with layering, and is cool in the summer and offers sun protection. They can be machine washed and dried or washed out in the sink and will be completely dry in a couple of hours. Great company and product.

I ordered this top for my wife and she absolutely loves it. It is silky soft and breathes well. Great base layer. Very pleased with Patagonia products and of course with ZAPPOS as well!

Great Top - This top is great on its own, under a sweater or even under a t-shirt. This top is very comfortable and hides nicely under things (It’s very thin!).

Bought this for our ski trip out west. It was 6 degrees out and I was thankful for all my layers! Great base layer!

I was heading to the Vancouver Olympics and looking for something to add an extra layer of warmth; I decided to take a chance on this one. I wore it under sweaters and turtlenecks during some of the outdoor events and was very pleased with the extra warmth it gave me. It really is incredibly thin and silky and you don't notice it at all under your clothes. It is true to size and I really appreciated that it was long enough to actually tuck into my jeans (long enough even for low-rise pants). I was a little skeptical of the Gladiodor aspect and claim, however I actually ended up having to wear this top several days in a row without washing it and it DID NOT smell! Not that I recommend doing that, but when you're living out of a hotel room and need to improvise, you can. I am really happy with this top and will definitely buy again...probably an extra one so I don't have to wear it without washing!
