We built the Black Hole Pack because more often than not, your day has its own plans. This rugged, highly weather-resistant gear bag protects your belongings when the weather turns surly or your hike morphs into a contentious scramble. The large main pocket holds the lion’s share. An internal sleeve carries most 15" laptops or a hydration reservoir, and two mesh pockets equipped with a key keeper organize your phone and small items. A lid pocket for quick-grab stuff seals with a reverse-coil zipper; daisy chain lash points secure a skateboard or yoga mat. A zippered front pocket holds quick-access items. Compression straps on both sides cinch the load and/or secure external items. For carrying comfort, the backpack’s padded shoulder straps have a sternum strap. A molded back panel sheds moisture and allows a cooling airflow, and a simple waistband secures the pack. Made from 13-oz 450-denier polyester ripstop (50% solution-dyed) with a TPU-film laminate and a DWR (durable water repellent) finish.
