Outdoor backpack for trekking/ backcountry/hiking

Reselling this backpack which I had bought on here used. There’s a zipper in down the middle to access the inside there’s water holders on the sides . The seller and I are unaware of the Liters but it should be less than 65L. The backpack has had some wear and tear but no holes that I’ve seen. I’ve only used it once on a section hike of the LT. Measurements from previous seller: both are measurements of back board W:10 inches L:23.5 inches
