+1 on the quality.
I have the Expedition Panniers, and love them. Never had a leak. Their lightness- for something so solid is brilliant
I love the D-rings on these though and would love to have them on mine. Also- knowing that they will fit perfectly on the Wolf Racks I have on my F650GS- these would be a great second set of bags for a longer trip where I wanted to carry more- lower.
