There are several drawbacks to these bags (I didn't really expect Tumi for this price). The first is that they are not very strong; the fabric wears out easily and the sides bend. The second is that the pull up handle on each of the set is loose. The third is that the "carry-on" is internally sized not to hold much and the outside pockets are small (I could not get a 15" Power Book in the "big"one.) The fourth and most irritating of all is that there are no side handles making it difficult to lift and load all of the bags. I suspect that with the weak inner material the handles would just pull out. I do a lot of traveling and cannot recommend these bags for the regular traveler or even students going away to school. Sorry guys I sure can't imagine a polo team using these! [I did order two sets through Amazon and they were shipped from two different  warehouses and arrived (even with Prime!) several days apart.)
