The Black Hole 25L Backpack from Patagonia.
Patagonia built the Black Hole backpack with an urban aesthetic and an alpine psyche that scoffs at rough granite, half-frozen mud and angry chaparral. Highly weather-resistant, their Black Hole Pack protects your gear from rough handling and miles of abuse. The large main pocket holds the lion's share, with an internal sleeve to carry most 15” laptops or a hydration reservoir, and a mesh pocket equipped with a key keeper and an organizer panel to hold your phone and zip drives. 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. A stealthy zippered front pocket holds quick-access items and side compression straps cinch the load and/or secure external items. A molded back panel sheds moisture and allows a cooling airflow; padded shoulder straps and a simple waistband secure the pack.
