Can anyone recommend a well built and preferably waterproof tailbag? I currently have this bag: which is a mini grantour bag from Kuryakyn. Two buckles have failed and the main zipper pulls open on its own. It also requires a separate rain cover. Having separate compartments is nice for glasses, GPS, etc., but for the cost, I am most disappointed in the quality. I have sent them an email asking for some customer service, so I will see what happens. Meanwhile, I like the Kreiga bags for their toughness and waterproofness (is that a word?), but they won't be as quick and convenient to get at something when I need it. Roadgear has a euro model tailbag that looks decent, but it needs a raincover. Can anyone here recommend a good tailbag for a street bike that is robust and hopefully waterproof without a separate cover? If not waterproof on its own, how about just robust and truly waterproof with its cover in place?
