The sliding door on a beater climbing van inspired the design of the instant-access Ironwood Pack. This simple panel-loading backpack provides fast access to your urban or outdoor gear. The main compartment holds a rain shell, lunch, your books and a tablet. A raised, padded sleeve protects most 15″ laptops. A zippered pocket on the front panel holds your boarding pass and wallet. The padded Human Curve shoulder straps provide all-day ergonomic comfort for carrying a full load of chemistry textbooks. Finer points include a top-mounted, reinforced haul handle, an ice axe loop and exterior lash points for a yoga mat or skateboard. Made from 600-denier 100% recycled polyester with a 200-denier polyester liner. All fabrics have a DWR (durable water repellent) finish.
