Suitable for everything from fast-and-light overnights to a semester abroad, the Mystery Ranch Stein backpack comes with plenty of features for your next adventure. Made of durable 210d and 330d nylon fabric, it has a 65-liter main compartment with a full-length urethane side-access zipper that makes packing and finding your belongings a breeze. The frame is made of carbon fiber, which is stiffer and lighter than traditional steel and aluminum frames and better at bearing heavier loads. An integrated Speedzip sleeping bag compartment lets you grab your bag without opening the whole pack. The lid has two zippered pockets and can be removed and converted into a lightweight fanny pack for shorter day trips. Horizontal and vertical compression straps help you reduce overall pack size, while plenty of integrated loops let you lash on items like water bottles or ice axes.
