The tough and highly weather-resistant Black Hole��_ Pack protects your gear from scuffs, scrapes and miles of rough handling. The large main pocket holds the lion��_�s share, with an internal padded sleeve that protects most 15" laptops or holds a hydration reservoir, and a mesh pocket equipped with a key keeper and an organizer panel to hold your phone and small items. The bucket-style opening replaces a traditional lid and contains a small stash pocket that seals with a reverse-coil zipper. Daisy chain lash points secure a skateboard or yoga mat, and a stealthy zippered front pocket holds quick-access items. With padded shoulder straps for comfort and a molded back panel that sheds moisture and allows a cooling airflow. Made from 13-oz 450-denier polyester ripstop (50% solution-dyed) with a TPU-film laminate and a DWR (durable water repellent) finish.
