I have been using the "Combat" vest this year. The material has a flaw in that it unravels behind the seams and leaves strings in the pockets. I've just been clipping them out, but a dedicated person could probably melt the threads with a soldering gun or some such and stop the unraveling. I figure I'll wear it out before the threads disappear. At the price, I could easily replace it each season. I had the cotton "Safari" and while I liked some things about it, I wore holes in it fairly quickly. It also started stinking from sweat, sun screen, and insect repellant after a fairly short period of time, which was OK for the track when I was away from everyone, but not suitable for polite society. I use khaki since it is very hot trackside in Kansas (I measured 120ºF about a month ago) and I figure black is not the best choice for those conditions. When this one wears out, I will buy another just like it.
