He may be retired, but Bob Beckman made a line in lightweight, high modulus fabric that looked pretty light. they zipped together to make bigger or smaller panniers to fit the tour. Years ago, he made panniers expressly to fit Bruce Gordon racks. They were way over built, and my set is heavier that my Ortliebs. He used large zippers, removable dividers, they were limed in bright yellow, and had a set of compression straps. Altogether state of the art for 1985-95. The fabric on mine has had a lot to its laminated waterproofing peel off, but the have removable covers that work fine.
