tx. Its a "gearsack" aussie brand tailpack, i challenge you to find one, my pals had them and i scoured the internet and ebay.... they ARE 100% waterproof (i know everyone claims it - but that bit of kit truely is) - can get enough clothes, tools, toiletries in that thing for 10 day trip + excess, inc champagne bucket and a couple of bottles of pink for the missus whilst zipping back through Reims... granted bungies were involved but the bucket was in the pack..
