I like this shirt alot as it breathes well and is a nice loose fit.  I like to wear over a T or other skimpy top & then take off when it gets hot, or put on when weather cools down.  The roll up sleeves are a little "shaggy" as fabric is not stiff for those who like that "perfect look" so with that being said - it's not for those who like a "crisp-looking" shirt.  I use this for hiking, camping, sailing, beach activities and ventures and own three (lime green (4/2001), black (6/2012), white (5/2005), bone (5/2012)).  I am a little miffed that ExOfficio deleted the square bottom on this shirt (at least it is not on their website) - my only gripe, as that made it a GREAT looking shirt.  Now it is just a GOOD looking shirt.  If anyone knows of this shirt in a square bottom at any stores, please let know.  Thanks!
