Long before I was a backpacker, I toured various countries with a buddy, unsupported (just the two of us with our tents/sleeping bags/gear/maps/etc.). Usually three weeks at a time. I toured Scotland, Ireland, NE France, East Germany, New Zealand and Arizona like that, and Holland for a week.
When I turned 50 a few years ago, I decided to celebrate with a 9-day bike tour with my buds (two of them) in Vermont. One of my buds, Thomi, lives in Heidelberg, but he was more than happy to fly over here and celebrate with me. I promised when he turned 50 I'd fly over to Germany and celebrate with him with a short bike tour. That's this year. I'll be there Aug. 18-28.
Bike panniers are, in my opinion, notoriously overbuilt. And not the lightest things in the world. So I talked to, who else, Chris Zimmer about making some out of, what else, cuben. He did a fantastic job! Even made the top attachments exceptionally adjustable. Also had him make a small under-seat tool/tire bag. His wonderful craftsmanship is below.
The seat bag weighs an ounce. I sent Chris an Ortlieb pannier to use as a model. I sent a front pannier, and asked him to size up to make rear panniers. My new rear cuben/dyneema panniers weighs 6.5 oz. each, which is about 1 lb. 2 oz. less than the front pannier I sent him. Way cool!
