They say life is a journey, not a destination. So we designed the Black Hole(TM) Pack to carry everything you'll need along the way. Our tough and highly weather-resistant Black Hole(TM) Pack protects your gear from scuffs, scrapes and miles of rough handling. The large main pocket opens quickly with a half-moon style zipper and holds the lion's share of your gear. Internal features include a padded sleeve that protects your 15" laptop or holds a hydration reservoir, and a mesh pocket equipped with a key keeper and an organizer panel to hold a phone, keys, wallet and all of the small items of everyday life. A large front stash pocket keeps a headlamp, electronic paraphernalia and your guidebook handy. Daisy chain lash points provide multiple options for securing a skateboard or yoga mat and stretch-woven side pockets keep water bottles, map or a pair of gloves right where you can reach them. With padded shoulder straps for all-day comfort and a molded back panel that sheds moisture and allows a cooling airflow.
