To make a long story short, all of which are worth the money, the more expensive the shirt all the clever details. All shirts are very well made and comfortable to wear. The shirt NosiLife is rather small for XL, from I'd say it's a Grossel L. On the shoulders it fixes into place, in the abdomen, it is too far but still OK. The color is more of a safari beige. Well, I think the air vents on the back and the zip pocket. The shirt Kiwi is also very comfortable to wear a nice casual shirt without ventilation. In dark blue, it looks good and fits in size L good but is on the belly cut loose. The shirt of Columbia Silver Ridge sizes bigger. It also has air vents on the back and is very comfortable to wear. The Fabe Grill is an olive gray.
