The ExOfficio Geotrek'R shirt is perhaps one of the best shirts I have owned. Why? Well, for one thing the materials of which the shirt is constructed are VERY durable, being made from rip-stop nylon. This was the biggest factor for which I purchased this shirt. You can't go wrong with nylon; the stuff lasts forever. Furthermore, the shirt feels like your wearing nothing at all, for it is super lightweight and very breathable. The shirt feels as though it is a dual purpose article of clothing; semi-casual wear or something you'd wear when your camping or making a day hike. I purchased this shirt to help me feel comfortable and look professional while working in the EXTREMELY hot climate of Iraq. After wearing the shirt all day and  being outside in 115 degree weather, the shirt looked as though I had just purchased it and I was comfortable because it didn't look as though I was wearing a shirt that was sweat stained or dirty, despite the austere conditions in which I found myself.  The shirt is wickable, has a 30+UPF sun guard protection rating (meaning the shirt protects your skin from the sun's rays and withstands being in the sun without becoming damaged itself, such as fading.), and the shirt will dry rather quickly if it becomes wet. I tested this by completely submersing the shirt in water and letting it dry outside in 90 degree weather (which is night time temperature in Iraq!!!). It was completely dry within approximately 10 minutes. The shirt is wrinkle resistant, so it always has a nice, ironed look.

I could not find anything wrong with the shirt. The stitching and cut of the shirt is meticulous and well made. I think the only thing ExOfficio could have done better is offer a broader selection of colors for the shirt because most of the colors offered for the shirt seem a bit extreme or radical. Other than that, the shirt is the best around in quality and construction. You won't go wrong in purchasing this shirt.
