I've used this backpack several times and it's awesome! I'm only selling it because I have two of these bags and no longer need both of them. This Glacier Blue color is Limited Edition and no longer available for sale on the Calpak website! There's a couple small blemishes on the outside of the bag, but overall it's in very good condition. Dimensions: 18" x 12" x 7.5" This bag fits perfectly underneath the seat on the airplane. Has a luggage trolley sleeve for effortless transport during travel. Padded laptop pocket fits laptops up to 17”. Adjustable padded shoulder straps with sternum strap for optimal comfort and support. Durable carrying handles ensure long-lasting durability and convenience. Compression straps with buckles for secure and organized packing. Detachable adjustable shoulder strap offers versatile carrying options. Clamshell opening provides convenient access to contents. Interior compression strap keeps items secure and prevents shifting during transit. Crafted using 27 recycled plastic bottles, this product embodies our commitment to eco-consciousness and functionality. Website: https://www.calpaktravel.com/products/terra-26l-backpack-duffel
