Oniwrote a review of Patagonia Fore Runner Shirt - Sleeveless - Men's on April 19, 2016
Familiarity: I've used it several times
Fit: True to size
This is the sleeveless version of the shirt that Patagonia is marketing as bike jersey. Didn't really need another bike jersey but I can get by with a sleeves shirt for casual or the gym (I'm huge like that! Ha!). And I liked the gray color better in this style.
It's okay. I have some other sleeveless Patagonia shirts and that material is more textured so it's cooler. This one isn't too bad, I've worn it on a ride and it's comfy, it's just not special. Wicks reasonably well, dries well. It doesn't smell when I sweat, which is nice. One of the things I don't like about it (and I realize how dumb this sounds) is that it doesn't look cool. Take a look at a Fox Attack jersey. While it's more expensive, you can take a look at the different fabric types and cuts and vents. This is simple. But works.
I got the large, and it fits well. Not too tight or loose. Might get the zipped version if/when it comes out in this colorway. Maybe.
