I'm not sure you can put plaid & cool in the same sentence w/o violating some sort of universal law or another
On a more serious note - I've been idly wonderin' the same (nice panniers, not plaid lol) for my Rollfast... I'm thinkin' mebbe smaller ones ofn' a Harley Sportster... While it's true HD stuff is a pretty penny, there's "off brands" too.
Worth lookin' into anyway
