Our Take:
4.4/5
Certified

The Patagonia Black Hole MLC ($239) is one of the roomiest bags we tested, and it ably splits the difference between a suitcase and a backpack. Its padded hipbelt and shoulder straps make it fairly comfortable to carry, while a TPU-laminated shell and PU-coated liner offer reassuring weather protection. It’s bulky, lacks external pockets, and the Black Hole sure ain’t cheap, but all in all, we’re fans of its hybrid design.

Pros

Padded hipbelt makes the pack comfortable to carry when fully loaded.
TPU-coated shell and PU-coated liner provide durability and weather resistance.
Solid internal organization for both large and small items.

Cons

May be too large to fit in the overhead compartment of small aircraft.
Main fabric isn’t as thick as the materials in more durable models.

I’d used previous versions of the Patagonia Black Hole MLC, and this updated design is much better. The improvement is mainly due to the new padded hipbelt, which makes a huge difference once the pack is loaded. With weight on my back, I could shift a meaningful portion of the load onto my hips instead of letting everything pull at my shoulders. Even if I was carrying a lot of weight, the thin-but-dense padding on the shoulder straps helped prevent soreness.


I tested the Patagonia Black Hole MLC across a month of travel, and it stayed comfortable in the ways that matter when your entire life (well, at least temporarily) is on your back. With up to about 25 pounds inside, the pack still felt stable and supportive, and it held up well on a 2-mile walk that would have been too much for some less comfortable models, such as the Topo Designs Global or Yeti Crossroads.


Ventilation is the main comfort drawback. The Black Hole’s backpanel does not have prominent airflow channels, and in warm, crowded conditions, my back got sweaty fast. The hipbelt is removable, though, and can convert into an over-the-shoulder strap for briefcase-style carry. I like having that option, but backpack mode is what I defaulted to because it is simply more comfortable once the bag is loaded. The shoulder straps also stow away cleanly, and the sternum strap helps keep the harness settled when I am moving quickly through airport terminals.

Rather than a whole bunch of small pockets and compartments, the Black Hole’s organization revolves around two main zippers, each of which opens the bag suitcase-style. One clamshell allows access to the main packing area, and the second opens a compartment with an admin panel and the laptop sleeve. If you like having big items and small items separated into two distinct areas, this layout feels intuitive and easy to maintain.


The main compartment is spacious and works well for holding clothing. A zippered divider keeps the primary packing area secure, and the opposite side includes smaller zippered pockets that are ideal for socks, underwear, hats, and other loose items. I like that the system keeps everything visible and contained once zipped up, especially when I am living out of the bag for multiple days.

The second clamshell sits closer to the backpanel. One side includes a spread of sleeves and pockets for chargers and accessories, plus a key clip. The other side houses the laptop compartment, which is notably large for this category, and it can fit up to a 19-inch computer. That size makes the Patagonia Black Hole MLC feel more like a true work-and-travel crossover, not just a hauler with a token laptop slot.


This pack’s major design fault, though, is the lack of exterior pockets for storing things you want to grab on the go (that includes a water bottle). If you’re someone who tends to keep everything in your pants or jacket pockets until you get to your destination, you’re all good. But for travelers who like to frequently return to their pack while in transit, the Black Hole makes doing that a more awkward proposition. The spartan exterior is an odd counterpoint to the feature-heavy interior, which my wife wished wasn’t so cluttered with options. Travel pack storage is perhaps the most subjective category of them all, though, so you may like the Black Hole’s layout more than she did.

This bag feels quite well-made when it's in your hand (Patagonia’s usual quality is no surprise), but on paper, its specs are quite a bit thinner than other leaders in the category. The Black Hole is made with a 300-denier ripstop polyester that has a TPU film laminate, and inside it has a polyester liner with a PU coating. The exterior has one of the lowest denier ratings of any travel backpack we've tested. For comparison, the REI Co-op Ruckpack is made with 400-denier polyester, while the Thule Aion has 600-denier polyester material. Neither of those models ranks near the top of the class for durability, and the Black Hole doesn’t come close to approaching the toughness of bags like the Topo Designs Global, with its 1,000-denier body and 1,680-denier back.


However, the Black Hole’s construction still feels good, all things considered. The zippers operate smoothly, and nothing about the bag came across as fragile during real-world use. Its TPU coating helps resist abrasions and offset the polyester’s thinness. When I was living out of the Black Hole for several weeks, it emerged without any issues. There aren’t any obvious reinforcements in high-wear zones, so I would not treat it like a pack designed to be dragged across rock or pushed into constant outdoor use. But for typical travel, the Black Hole held up well and felt like it could last for years if you are not trying to punish it.

The Black Hole’s weather protection is one of its strongest attributes. The TPU-laminated shell helps water bead and roll right off, and the PU-coated liner adds another barrier that can keep moisture from pushing through if the exterior gets saturated. I have not used it in sustained, genuinely nasty weather, but the material inspires more confidence than a simple, durable water-repellent finish does.


In real-world terms, this is the kind of bag I trust for brushing off drizzle, spills, and being placed on wet ground for a decent amount of time. It is not fully waterproof—the closest you’ll come in this category is the REI Co-op Ruckpack, which has a rain cover—and I’d obviously prefer to find shelter quickly in heavy precipitation. But the Black Hole is still one of the best performers in this metric across the whole category.

At 3 pounds, 10 ounces, the Black Hole is heavier than many travel backpacks, and you feel that heft when you lift it into an overhead bin. In my view, though, the weight felt justified because it combines plenty of capacity with a supportive carry system and solid weather protection. This is not a bag that feels heavy without a reason.


The bigger story is bulk. The “MLC” at the end of the Black Hole’s name stands for “Maximum Legal Carry-on,” and this is definitely a big bag. It should fit into most overhead bins on a flight (hence the moniker), but you might get some guff on smaller planes or budget carriers. Compression straps help rein in the size a bit, but it is still a beast. It is also not a realistic under-seat personal item.

Longevity

Choosing durable outdoor gear is perhaps the most effective way to reduce environmental impact—the longer it lasts, the less it needs to be produced. Our proprietary longevity rating evaluates overall build quality based on factors such as materials, fabric denier, component durability (including zippers and toggles), real-world performance as reported by our field testers, and our experiences with the brand.

I tested the 45-liter Black Hole, and Patagonia also makes smaller versions (22 and 30 liters), plus a wheeled variant. I stand 6-foot-2 and weigh 175 pounds, and the pack felt appropriate for my size and shape when I was carrying it. It did not overwhelm my body, and the hipbelt fit me well enough to actually transfer weight to my hips the way it is supposed to.


However, smaller travelers might get overwhelmed a bit. My wife is 5-foot-2 and weighs 103 pounds, and on her, the Black Hole looked and felt oversized, and the straps had to be cinched down aggressively just to get it to sit acceptably. If you are on the smaller end of the spectrum, I would look hard at the 30-liter size before committing to the 45.

Cotopaxi Allpa 42L ($250): A More Streamlined Alternative
Travelers who prefer a smaller, more straightforward pack will find the Allpa 42L a worthy alternative. It’s slightly more compact at 42 liters and has a noticeably pared-down layout. While the main compartments are similar, the Allpa forgoes theBlack Hole’s organization panel in favor of two simple top pockets and a separate laptop sleeve. Still, it includes a mesh water bottle pocket, something we missed on the Black Hole. The Allpa’s build is tougher as well, with a thicker, 840-denier nylon exterior. Both packs offer similarly padded shoulder straps and hipbelts that stow away when not in use. However, only the Black Hole’s hipbelt can be reconfigured into an over-the-shoulder strap, which increases its versatility. But if you don’t need that, or any of the Black Hole’s additional features or space, then the Allpa will serve you well—you’ll just have to pay a little more for the durability boost. For more, read our Allpa Travel Pack review.


Topo Designs Global Travel Bag ($199): The More Affordable Option
Like the Black Hole, the Global Travel Bag also has over-the-shoulder carry and features two clamshell openings—what it lacks, though, is the MLC’s hefty price tag. It also goes a step further with an additional dorsal pocket, a separate laptop compartment, and two water bottle sleeves, making it an impressive value buy, comparatively. When it comes to carry comfort, however, the Black Hole’s shoulder straps are more ergonomically designed, and its hipbelt is padded and more supportive. In addition, the Black Hole is coated with TPU and PU to ward off precipitation, though the Global counters with thicker fabrics overall. And while both packs have stowable shoulder straps and hipbelts, the Black Hole offers 15 liters more capacity. If you don’t need the extra space or aren’t planning extended trips, it’s hard to justify. For more, read our review of the Global Travel Bag.

4.4/5

The spacious Black Hole MLC melds the capacity of a duffel with the convenience and comfort of a travel pack. Its roomy design and well-built carry system let you haul your stuff for sizable distances without discomfort. That said, we wish it had a dedicated water bottle pocket, and its size may feel bulky to travelers with smaller loads.

Is the Black Hole MLC for You?

We’d pick the Patagonia Black Hole MLC if you’re in it for the long haul—both in terms of the length of your travels and the distance from your transport to where you’ll lay your head. This travel pack has a ton of space and a carry system that makes long days feel doable on foot. It also has better weather protection than most competitors offer. If you need a super-durable bag, want more external organization, or are sticking to a budget, we’d look elsewhere. For the overpackers among us, though, it’s a quality choice.
