Sure, it's a stupid question. I recently ordered some pants from them. I was trying to get double knees but they kept saying double front. I finally decided that there were other stats that I cared more about than that, and I went with them. The pants arrived and...big mistake. I don't mean unwearable. I can do that. The thing is I wanted tough pants for those outdoor jobs, messy stuff, etc. How do I get double knees next time?
