These vests are fantastically well constructed for the price you pay, but that's of little comfort when they don't fit. By my estimation, my vest is 3 sizes smaller than it's labeled to be. These are also short vests, so if you're a beer-gutted biker with low-slung jeans, the vest won't reach your pant-line, even in a tall size. That's fine for skinny folks, but I don't want my love handles framed for display by my clothing. Despite the advertised big sizes, these vests are NOT for big folks. If you need bigger than a 2x in normal clothes, the largest size of this vest won't work. If you wear a 2x, order the 5x. If you're 5'9" or taller, get the tall size...unless you like a gap between your vest and pant-line or you wear high-waisted mom jeans. Good luck.
