Selling my lightly used Kelty backpack. Capacity is 90L.
It has an internal frame with dual aluminum stays, padded adjustable shoulder straps, sternum strap, padded hip belt with mesh pockets, ventilated back panel, multiple compression straps, zippered top lid compartment, front gear attachment points/daisy chain, side mesh pockets, and various adjustment and load-lifter buckles.
It's been a solid and reliable hiking pack. I've included a screenshot of additional details from REI's product description, as well.
