OSPREY sirrus26 Osprey Sirrus 26 Raincover Osprey backpack, size S, with a capacity of 26L. Features a blue mesh design and a back panel for a comfortable fit. This lightweight, mid-sized pack is equipped with many user-friendly pockets, suitable for day hikes to one-night, two-day mountain trips. Height: Approximately 53cm (outer dimensions) Width: Approximately 33cm (outer dimensions) Depth: Approximately 18cm (outer dimensions) Measurements are approximate. Please allow for some margin of error. The mesh back is quite comfortable, and as it's a women's model, it fits the body well. I've used it for a long time, but I haven't been hiking recently. I've taken good care of it, and there don't appear to be any major stains at first glance, but there is some fading, the Osprey mark is faint, and the elastic in the side pockets may be stretched. Please check the product images carefully. This is a used item, so please refrain from purchasing if you are looking for perfection or are overly concerned about details.
