A backpacker's backpack, The North Face Zealot 70 is a multi-day pack that is constructed of super durable waterproof ripstop 315D auto-airbag fabric that is welded at the seams and impervious to the elements. For the support of large, heavy loads the Zealot 70 (AP0F) has an X Radial 2.0 frame that is lightweight, but exceptionally strong. Some of the details mentioned in Zealot 70 reviews have included the Opti Fit torso adjustment system, the molded foam back panel, anatomical hipbelts and shoulder straps, and a stowable side water bottle pocket. This multi-day pack is top loading by design, but there are a multitude of storage pockets. It is also hydration compatible, there are many gear loops, and the dual pivot hipbelt distributes the load across your lower body.
