I am bit of a pain in the rear end with how picky I am about things, I even get to myself...  That being said, I purchased two sets of each size of this Xover Line by Thule.  My family now has a full set of matching luggage that is so versitile that each family member loves their bag.  Even with all of the different types of Traveling and also different sports and hobbies we are accomodating, these bags are fitting in quite well with everyone.  I spent over 2k on the luggage but it is worth every dime.  This bag, the 56L, is definitely the favorite though. We purchased two and it looks like we may still need another.  Perfect size bag with perfect storage compartmets to keep everything safe and seperate.  The hard shell compartments are available on every bag including the backpacks I purchased. I was able to ditch a case for my Oakleys.  Nice job Thule, it's definitely a case of getting what I paid for.
