Summary
The Patagonia Black Hole MLC 45L blends suitcase-like organization with backpack carry, offering a roomy 45L capacity, a padded hipbelt and shoulder straps for comfortable carry, and strong weather protection thanks to a TPU-laminated shell and PU-coated liner. It's bulky and lacks external pockets, but its build and hybrid design make it a solid choice for long trips and as a travel-work crossover.
