For sure the Gobis are known to be really thick because of their double wall...
I really don't know what to order. Before visiting this foruml, I did know anything about the caribou / pelican luggage (we don't have them in France, I guess). And after reading a few pages of a vendors post, I'm convinced they are well made, really tough, durable, and not SO expensive. They are not really wide, that's a good point, but you can't load them by the top, and that could be, in my opinion, a problem (I think a top loading is better). The only thing I'm definitely wondering on is to conserve or not my Givi rack, that have no reinforcing bar at the rear.
Without reinforcing bar, I'm not sure I would be tough enough to carry a travel loading. Any feedback on this type of rack??
