Here we go again. Most threads will give you folks that say not to use them. Most jeans are not designed to flex in the crotch. Buy some jeans with a diamond gusset in the crotch. I have jeans from two different companies and both have different good features. www.duluthtrading.com www.gussetjeans.com Diamondgusset has jeans with kevlar for motorcycling or regular jeans. Either company makes a good product. I have some of both. I also have a pair with the kevlar for motorcycle use. Duluth trading catalog has a bit of humor in it. Good luck in your search. I enjoy the jeans for colder weather. Duluth Trading also has lots of coomax items. Shirts, socks, bandannas, and more.
