Outstanding to say the least!!!!
Love these straps!! I don't do much backpacking, but on my travels to and from work and also the airport, they provide a sense of security and pull some pressure off my back as well. I love the tiny pocket located on the straps thats good for storing things like your debit card or ID for easy access. This is one of my favorite things as I travel through the airport while showing my ID to save me some time and knowing that it is in a safe spot. I detach the waist straps when not using them just so they aren't in the way. But this was an awesome addition and purchase to my 21L and 31L bags.
