I think I spent 2 solid hours on the Internet trying to find the right pannier. It wasn't until I searched via, "photos only" that I finally found the Frost River product. It was like trying to find a needle in a haystack. Search engines all had directed me to cheap Chinese products, and modern stylers that did not have full top closures or were made of rubber products that do not breathe, and look like bags used on a skin diving trip. The quality of the 61 is absolute top drawer as are the materials. I couldn't be happier! High quality costs, and I'm O.K., with that! Carry on...
