Have two of these shirts and they are fantastic. I can wear them in the office or out in the field under body armor. I am 6'3" and 225 lbs and the XL is perfect. I love Arc'teryx products but this is one of my particular favorites

I am 6'-1", 255lbs , 48 chest and 40 waist and got XXL. I have had other Arcteryx shirts in XXL and liked the fit. This one is very long and slightly looser than others. I loved the fabric and feel and quality looks great. Unless you tuck in your shirt or are 6'4" or taller this shirt will look too long on you. I am not into tight shirts being a bigger guy but this looks just a little too loose and probably needed an XL. As far as length it was about 9" past my belt line. The photo looks long but didn't see any other reviews stating it being so long so I took the chance, it is possible the smaller sizes are not as long.

Standard outdoor industry plaid shirt. Great fit, not too tight, not too loose, good collar, and does not wrinkle easily.

I got this shirt for my brother for his birthday. He loves it! it works perfect for wearing to work as well as casually on the weekend. He fit his really well and was true to size.

Love this button up shirt, the monochrome plaid, cut and style is great. This seems like a "fitted" cut and is form fitting in the torso area. Great shirt!

As you would expect from Arc'teryx (and this high price), it has a nice cut (note that a relaxed fit in Arc'teryx terms is still somewhat trim), great seems (several of which are nicely hidden) which gives a very clean look. I appreciate that they didn't put a big logo on it other than a fairly discreet Arc'teryx bird in the middle of the back. The fabric is soft and smooth.

I like to wear shirts like this untucked and I feel for that, the shirt is a bit long. The length and the price are the only reasons I'm knocking one star off.
