This is an older model. I purchased it in 2021 and used it for hiking about 10 times. I am selling it to organize my belongings. It shows signs of use overall, but there are no noticeable stains, scratches, or holes. Please consider this a pre-owned item, and refrain from purchasing if you are overly concerned about its condition. The Ducan Spine 28-35 is a groundbreaking hiking backpack that improves comfort with Active Spine technology. It excels at weight distribution and offers excellent freedom of movement for the hips and shoulders. It is very lightweight and features pockets that can be attached to the shoulder straps or hip belt, as well as side pockets that are easily accessible while walking. In addition to its high level of comfort, this practical item also offers a variety of packing capacities.
