Gusseted-Crotch Pants

I learned the difference between a gusseted-crotch pant and a non-gusseted one while shopping for shorts online. Gusseted ones are better for rock climbers because they prevent the shorts from splitting while you hyperextend your legs out of socket. They must be great for rock climbers (and other athletes like yogis and gymnasts), and have great practical construction for durably-built clothes, but why must they look so ridiculous?
