In an other thread I noted I returned the Ortleib Rollers I recently purchased, then on a whim I checked FB Marketplace and there were a set of Jandd Large Mountain panniers selling for 20 bucks. Couldn't pass on them and sure am happy that I didn't. Each pannier is about 33.5L providing a total of 67L. Perhaps my math or measuring is incorrect and they are 70L, but who really cares?
The sleeping bag or quilt I use take up a full pannier, and the when using the smaller ones the bag or quilt had to go into a stuff sack strapped to the rack. What I really like is the organizational perfection these big bags provide. Because I switched from only using zip-lock bags to half zip-lock and half waterproof stuff sacks for my stuff, vertical placement in one pannier works really well. Nervana found by accident.
One more thing to note is I have moved all tools, tubes, levers, and chain lube from the h-bar bag to the top left rear compartment (kinda like a pocket, yet better) which reduces the weight in the h-bar bag by a pound.
