This backpack is new and never used. It has room for a 2-liter bladder for liquid/ice. When I opened it, it didn’t have the bladder and I had removed the tags. It has a fleece-lined valuables pouch with a water-resistant zipper to protect your important stuff. Room for a 2 Liter bladder Mesh padded back with hideaway waist strap. Organizer pocket with key clip. Stuff pouch and dual zipper main compartment for storage and organization Measurements are 17.5" x 8.25" x 4.5" All the items I post are straight out of my closet, purchased and owned by my family and I. I am currently downsizing so I am selling all my beautiful items that are new and items that are in good, great, and excellent condition. HAPPY SHOPPING AND THANKS FOR LOOKING!
