Travis Tzioumis wrote a review of Icebreaker Departure Shirt - Short-Sleeve - Men's on September 29, 2014
Familiarity: I've used it once or twice and have initial impressions
Fit: True to size
Very comfortable and light weight. I don't find this piece to be itchy at all, if you are sensitive to merino you might have a different experience. It fits great around my shoulders and chest, but does run a little bit long. I wouldn't suggest sizing down since the rest of the shirt fits great. Kept me comfortable on a hot day short hike with the pups.
My measurements: 37.5 inch chest; 19.5 inch torso; 15 inch neck.
6'0" 155 lbs and I wear Medium.
Also, it's important to note that the Night color is more of a dark blue than the photos show. I'll post a photo soon.
