Hi all, this is the Carryology x Trakke Muir Project Backpack Sling Hybrid Ultra Ecopak Backpack, a limited edition collab between the two brands!  Made with quality fabric and materials, including a custom made orange Scottish tartan fabric for the lining.  Very high quality hardware such as Fidlock and Cobra buckles. The unique thing with this backpack is that the top portion can be removed and used as a sling, and when you're on the go, it stays on the backpack, counting as one less carry-on if you're flying.  

Been used on several international trips and it's served me well. For the backpack, all the hardware works and in good condition still.  Inner lining is clean without stains or holes.  The outer itself is durable with no major stains or marks that I can see.  The top sling portion, which I did use much more liberally, does have a bit more wear on the hardware.  Orange lining has some very slight discoloration.  All patches are there on both pieces.

Thanks for looking!
