I used this panier and it's matching left sider on a self contained Pacific Coast trip of 38 days. They are heavy, but "bullet proof". They have an inside rain protector, which coupled with the optional rain covers, are completely waterproof. The attachment system is superb, easy to attach and rock solid. The only slight negative, which I informed Arkel about, was the fact that the top outside pockets tended to catch wind and billowed out, when descending hills. I cured this with duct tape, but hope that Arkel has done something to rectify this small annoyance.
