The 40L Black Hole has been the default answer to the question “what bag do you take on a long weekend?” for good reason. It holds enough for four days if you pack sensibly, compresses smaller when you don’t need the volume, and shrugs off the kind of abuse that destroys less serious luggage in a season.
The shell is 100D ripstop nylon with a DWR finish — not waterproof, but resistant enough that a damp overhead bin or a rain shower between car and hotel won’t ruin anything inside. Haul loops and compression straps are positioned to handle both airline overhead and roof-rack strapping. The large U-shaped opening gives full access to the main compartment, which sounds minor until you’re hunting for a charger at the bottom of a less well-designed bag.
The 40L sits in the useful middle ground between a small carry-on and a full expedition pack. It travels as cabin luggage on most European carriers, fits under a 4x4 seat, and doesn’t look out of place in a city. The Black colour is the right choice: neutral, doesn’t show wear, doesn’t attract attention.
