You should check out TE's website under knickers/capris. The Ibex El Fito wook knickers has a 20.5 inseam and the Sugoi Midzero RC Pro has a 20-inch inseam. Those are about as long as I've seen in a knicker. A couple of others have a 19-inch inseam--the Pearl Izumi Elite Thermal and the Terry Bella.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
