I love these back packs. I first bought one from a crowd funding site and have had years of use out of it. I bought a second one recently as we are going to Europe soon and wanted a small backpack which offers security and peace of mind. I love these bags and hope to get many more years use out of them
I love the idea of this bag, but was afraid that pulling the sack closed would be hard on my hands. It was not, and it really worked well on my trip. I wish it had and outside pocket or strap for a water container. Otherwise, it is great quality and easy to manage.
I haven’t carried the bag yet, but think it will be very secure. Just what I needed. It’s much heavier and stiffer than I thought it would be. And why does it make so much noise?
