not study enough for frequent travel [SEP] i purchased a set of two of these in january and just tossed them after a trip where both of them split at the seams if you are not a frequent traveler these are fine but we use them at least a month for anything from a weekend trip to a week trip to europe they replaced a set of rei bags that had one too many liquid leaks that did not get cleaned in time oops which lasted us years these made it just over a quarter of that timeours split next to the seams usually because something sharp like a toothpaste tube shifted in the bag and pushed up against the side i will not be buying them again and i am searching for something new again tsa please knock off the clear bags so i can use something more eco friendly like fabric
