I bought my first Royal Robbins 5.11 trousers from an outfitter back East in 1985, but lost interest after the company was rebranded to 5.11 Tactical, the word is toxic. After I bought my first pair of RailRiders I stopped wearing RR 5.11 pants — it’s a cotton canvas versus nylon thing. RailRiders ultralight ripstop nylon is very comfortable and great on long walks.
