I dont have a Givi, but I do have the JC Whitney large topcase. I too love it. I keep my helmet in there when im not on the bike (I always got crap from the road/chain on it when id try to use the helmet hook) as well as a warmer pair of gloves, rain suit, RAM mount for my GPS when no in use. You name it, for a day trip you can put anything you need in it. One of the best aspects of a hard top case in my opinion is when you're traveling, you can take it inside, load all your cloths, toiletries, etc (stuff you probably wont need on the road) and at the end of the day, take it into the hotel or whatever and get what you need out. Top case is my far the best (and most useful) addition to my bike
