This is an amazing, durable backpack that is made of the highest quality. No visible tears or signs of wear. Shoulder strap included. Measures 21” x 14” x 9”, and is 3 lbs when empty. Retails for $99.99 From RS website: “Carry-On with Confidence: It fits within most airlines' carry-on guidelines. (Note: It's possible to over-stuff soft-sided bags beyond carry-on limits, and risk rejection. Pack light!) Outside: The classic, Rick Steves outer-pocket design gives it a clean, efficient look. A full-length side zipper opens to reveal a 14" x 20" compartment (perfect for a jacket). Three additional front pockets, a mesh water bottle pocket, external compression straps, two grab handles, padded shoulder straps and waist belt, and a breathable mesh lumbar panel complete the outside. Inside: The generous main compartment includes adjustable compression straps, a clip-in document pouch with two mesh drawstring bags, and a full-width lid pocket. Convertibility: To use it as a suitcase (or check it as luggage), the shoulder straps and waist belt securely tuck away in the back. Handy D-rings give you the choice of adding our optional Over-the-Shoulder Strap [only one of these for sale for additional $10 upon request]. Expandability: Gain an extra 2 inches of cargo depth in a pinch (making it "fatter" than the carry-on limit, but perfect for checking).
