I couldn't find any results searching about hiking pants with reinforced knees. I'm curious about whether people here own or use summer-weight pants with reinforced knees.

I always find after a few days on the trail my pants' knees are dirty as can be, from kneeling for cooking, fire building, or just general wear. Also, with moderate knee problems already, a single thin layer of nylon isn't exactly good protection for my knees.

I find that sometimes I will zipoff the legs when I get into camp (if I'm wearing convertible pants obviously), just to keep the pants cleaner, even though that can end up with bug bites, muddy knees, or whatever.
