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 laptop sleeve protects most 15" laptops. A zippered pocket on the front panel holds your boarding pass and wallet. 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 pad or skateboard. The body is made from 600-denier 100% recycled polyester and lined with 200-denier 100% polyester. All fabrics have a DWR (durable water repellent) finish.
