This MacPac Torlesse pack is a Women's 65 litre, with an adjustable spine which is great for comfort and fitting, and generous mesh padding through the back panels. It is a top loading pack with two zipped pockets on the top (see photo 3), one large zipped pocket on the front, and an internal divider with large zip towards the bottom which is very useful for getting things out of the bottom of the pack, such as a sleeping bag. There are two open water bottle pockets, one on each side. This pack has served me well on the Routeburn, Kepler, Rakiura and Pinnacles tracks, and is in good condition.
