5.11 Tactical Rush Moab 6 Sling Backpack

"This 5.11 Tactical backpack features a durable canvas material and multiple compartments for storage. It's a comfortable sling design, perfect for everyday use or outdoor activities. Comes with adjustable straps and a padded shoulder strap." I used it for a year or so for commuting. It is very clean. The end of one strap is worn, but still holds. The cup holder sling is included (not originally sold with the bag.) I am open to reasonable offers.
