Cglex, having the bars inside may give you a few more centimeters of packing space for small items. However, I would much rather pack less in my suitcase than go through the trouble of steaming or ironing my wrinkled clothes when I have a meeting to rush to. So, I would definitely choose wrinkle-free packing over a little extra space. Plus, I am beginning to believe that Briggs and Riley offer the best warranty on luggage right now. Where Tumi offers 5 year warranty on their bags and covers airline damage only in the first year, BR's "Simple as that" warranty
covers all kinds of damage for the life of the bag. This to me translates to peace of mind!
