Great 3-season shirt.
Overall this is an excellent shirt. The material is exceptionally comfortable to wear. The shirt offers the usual 5.11 features - chest pockets (that have pen holes - yes!), hidden document pockets underneath the chest pockets, a concealed button-down collar and this shirt also has sleeve pen pockets. The length is perfect for wearing tucked in or untucked, the buttons are very solidly sewn and the stitching along the main seams also appears to be both durable and well made. So why only 4 stars? While the material is very hard wearing and is exceptionally comfortable to wear next to the skin, the material really doesn't wick sweat all that well, limiting this shirt to 3 season use or possibly use on cooler summer days. I recently wore mine in about 33 degree (centigrade) heat and ended up being a huge sweaty mess. Anything 25 degrees and under is fine but not for use in super hot weather. All that being said, this is a superb shirt for use during any 'normal' temperature weather. Highly recommended.
