We tried this pack out this past summer and loved it. To the point where we've made a limited run for you, our PRB faithful. There are only 25, so get them while you can. The pouch for a hydration reservoir makes water easily accessible while outdoors. (Hydration reservoir not included), adjustable straps to fit wearers of all size, lash points on the outside extend the capacity to carry extra gear, like hats, scarfs or trekking poles. lashing is included, clever design keeps water within reach, extra lash points for holding outdoor gear like carabiners and clips, our zipper opening holds secure when closed and easily opens for a wide view of the bag contents.
