Quality & Comfort
The quality of the recycled ripstop fabric with its TPU laminate is immediately apparent – it feels burly and highly water-resistant, ready for adventure. Users confirm it protects contents well. Handling it via the shoulder strap or side handles is comfortable enough for transit. However, backpack mode is where opinions diverge sharply. Many users find the straps basic and uncomfortable for extended wear. "Excellent build quality... awful backpack straps," stated one reviewer bluntly. The lack of a rigid structure also means the bag can feel poorly balanced and awkward on the back if not packed carefully.
Durability
Durability is a major strength of the Black Hole line. The recycled polyester ripstop fabric with its heavy-duty TPU laminate is exceptionally resistant to abrasions, tears, and weather. "My Black Hole MLC has been my only bag for three years... bombproof bag... keeps my stuff dry," shared a Reddit user. Users consistently report it holding up well to rough handling, airport baggage systems, and challenging environments. Patagonia's Ironclad Guarantee provides further assurance.
Packability
Packability is maximized by the simple, cavernous main compartment accessed via a clamshell opening. "Love how this looks, love how it's just a big cavernous compartment," noted one owner. The 45L volume allows for substantial packing, often suitable for trips of 1-3 weeks. However, the lack of internal structure and minimal built-in organization (just a couple of mesh lid pockets) means packing cubes are almost essential to prevent items from shifting and creating the awkward weight distribution users complain about. The external compression straps help manage volume.
Functionality
Functionally, the MLC excels in versatility and weather protection. The ability to switch between backpack, shoulder bag, and briefcase carry is highly practical for different stages of travel. The materials offer excellent protection from rain and spills. The clamshell opening provides easy access. Its primary functional weakness is the uncomfortable backpack carry for many users. "It's lumpy. All the stuff slides down to the bottom and feels bad shifting around on my back," is a common sentiment. It functions best when carried via shoulder strap or handles, or as a backpack for short distances only.
Value
Priced around $219, the Black Hole MLC offers good value for travelers prioritizing capacity, durability, weather resistance, and sustainability. "It's made from high-quality waterproof materials, the bag is sturdy and comes with a reliable warranty," supports the value proposition. However, if comfortable backpack carrying is a primary requirement, the value diminishes compared to packs with better harness systems. Its worth depends on whether its strengths align with your travel style and tolerance for basic carrying comfort.
My Black Hole MLC has been my only bag for three years... been through downpours... sandstorms... countless airport conveyor belts... bombproof bag... keeps dry. For minimalist traveler, perfect.

Did You Know?
The "MLC" in the product name stands for "Maximum Legal Carry-on," reflecting Patagonia's design intent to create the largest possible bag that would still comply with most airline carry-on requirements, maximizing packing space for adventure travelers.
