Patrick Goodmanwrote a review of Outdoor Research Astroman Shirt - Short-Sleeve - Men's on May 6, 2015
Familiarity: I've put it through the wringer
Fit: True to size
The Astroman was love at first touch. It was eyes-burning-with-sweat-hot out the other day cragging and this shirt wicked moisture, stayed dry and didn't stink. At the bistro later that night dinner would've been covered had I charged a quarter to each person who fondled my shirt.
I'm 5' 9", 167 and have a 40" chest - I find the large fits me perfect (airing on the roomy side) for casual wear and rock climbing.
I have had zero issues with durability; no problems with the snaps and the fabric is still like new after many washings and countless hours of wear.
