I'm military and travel on trips at least 5 times a year (not counting my leave time flying) and I was getting soooo tired of having to replace my suitcases all the time. I decided to get the Blackhawk ALERT Bag (hell, all my backpacks are Blackhawk, and have lasted for YEARS on many deployments!)I would rate it 5 stars for looks and 6 stars for zipper durability. I do not, however, think the bag is indestructible, but I do think it will last a lot longer than previous luggage I have bought. It wheels well and I really like the inside mesh zippered compartments. and you cannot go wrong with the large YKK zippers they use throughout...most luggage falls short on the zipper and that is usually where the problems start. I bought one for my wife for her Europe Vacation and she loved it (she travels a lot and had the same issue with her suitcases as well. My9 year old daughter is getting one next along with my son who will be going off to the military soon. Like I said, they are not indestructible, and I'm sure I will have to replace it in the future..but it won't be right away and I know I will replace it with another just like it!
I would also recommend the Blackhawk Tactical Ultra-light 3 in black (3 day pack) to go with as your perfect travel Backpack...everyone in the family has one of those as well
UPDATE: 2-11-2015 were now up to a total of four of these in the family, the original is still going strong- no complaints!
Combining exceptional compartmentalization and versatility, the BLACKHAWK medium alert bag unzips and folds out flat for quick, convenient loading. The BLACKHAWK medium alert bag is made from 1000 denier nylon with reinforced stitching for durability.
