I love this shirt! I bought it because of the color. I read in other reviews that it runs large, so I ordered the medium, which fits nicely and snugly on my unfortunately zaftig "L" middle -but I've lost 5 pounds!

I am wearing it right now. It's perfect as an under layer because it's thin. I also ... Read More

    I am wearing it right now. It's perfect as an under layer because it's thin. I also can wear it alone around the house or even to sleep in. I have worn it out, under a fleece vest or sweater, only because it's a bit clingy for my shape - until I lose that other 5 pounds!

    I wish I'd ordered two or three of these!

    I used to think that merino wool is only good in cold weather, but then realized that it is just as breathable and non-stinkable in hot weather. I bought this T with warmer weather in mind. Its my first I/O top in the "150" weight (almost a tissue T) and it is everything I expected-- super soft and breathable. I like the graphic a lot, but beware that the color is very purple - "grape jelly" is a perfect description.
    I'm usually a small in I/O and Icebreaker, but read that this top ran big and the XS is still a bit loose on me. That is why it is appropriately labeled a T shirt and not a performance base layer.
