Our Verdict

Out of all the new, ultralight packs that have finally made it to the women's specific arena, the Osprey Lumina 45 was hands down our favorite model. This pack combines the comfort and suspension that is typical of Osprey packs with an incredibly light, streamlined design. For the ultimate lightweight adventure, look no further than the Lumina to carry all your high tech, ultralight camping gear. The minimal design is a bit overwhelming at first, but we ended up enjoying the simplicity of the few pockets and features this pack offers.

Our Analysis and Test Results

As the lightest pack in this review, we were surprised to see that the Osprey Lumina 45 was also able to hold its own across the board in our performance comparisons. The feature set on this pack is simple, but all you need to travel light, while the suspension system provides support and comfort, even with heavy loads.

Performance Comparison


The beauty of the Osprey Lumina 45 is the fact that the pack is incredibly lightweight while still providing support and comfort. The shoulder straps and hip belt, while not excessively padded are wide and made of soft mesh.

This makes them both breathable and relatively comfortable as the width disperses the load and reduces the potential for hot spots. We enjoyed the shoulder straps on the Lumina more than those of the Osprey Eja 58, even though the latter had more padding. The Thule Versant 60, while being a much heavier pack and made for an entirely different purpose also had comfortable shoulder straps.

The waist belt  though lacking padding  is wide and made of mesh  making it very comfortable.

As far as weight goes, the Lumina soars above its contenders. This pack weighs a total of 1.86 pounds, which is 2-3 pounds lighter than the majority of the packs in this review.

The only two packs that come close to the Lumina are the Osprey Eja 58, which weighs 2.6 pounds, and the Gregory Octal 55, which weighs 2.58 pounds. This additional weight may be worth it for the versatility that both of these packs have over the very specific Lumina. The lightweight nature of this pack means that storage and extra padding are the two features that are skimped on. As far as storage goes, this pack is minimalist. The body is very narrow, so it's tough to fit much into it. Unlike models with wide bottoms, like the Osprey Aura AG, the Lumina does not have much room in the bottom of the pack for sleeping bags or bear cans.

The slim hip belt and shoulder straps of the Lumina are shown above. Though they are not very well padded  they are still comfortable and provide tons of ventilation.

The 3D-tensioned breathable back panel on the Lumina 45 feels like a trampoline against your back. Adding a bit of weight to the pack makes the suspension system more comfortable.

The idea behind this pack is that the suspension will still provide support via the aluminum frame while allowing air flow and ventilation through the mesh paneling. All of this makes for a comfortable carry, with very little additional weight. The Lumina is much like a very streamlined version of the Osprey Ariel AG or the Osprey Aura AG. Both of these packs provide plenty of comfort and support due to the Anti-Gravity suspension system, that somewhat resembles the suspension of the Lumina.

Ease of Use

This pack is one of the simplest regarding features among all the packs in this review. That means that the Lumina also gets a relatively high score in the ease of use metric as well.

The biggest downsides to the Lumina is that it is almost too small. It is difficult to get a bear can into the bottom of this pack because it has such a narrow profile, which can be a drawback if you are traveling in bear country. The Osprey Eja 58 is a better option for an ultralight pack that can fit a bear can. This narrow shape also makes it a bit tough to pack — we found that even a sleeping bag is hard to shove into the bottom of this pack without taking up too much space. For those who have pared down their kit to the essentials, the Lumina will feel like a dream, whereas those who want to bring more, may look toward a pack like the Osprey Aura AG.

Though the Lumina is narrow  it has the ability to extend upward with the added material shown above. This allowed us to get a little more into this streamlined pack.

As you may have guessed, the features of the Osprey Lumina 45 are on the minimal side.

Compared to packs like the Gregory Deva or the Osprey Aura AG, this pack is as complicated as a canvas sack. But of course, it is more advanced than that! The Lumina has a few large, external stow pockets, similar to the Gregory Octal 55. It also has a full-size lid with two zip pockets for small, essential items. Another feature that should be noted is the incredibly lightweight material that this pack is made out of. The nylon that makes up this pack feels as thin as a plastic bag and is what allows this pack to still have a frame and simple suspension system while keeping such a low overall weight.

Packing up the Lumina is no joke. There is no room for extra gear with this sleek little pack.

Best Applications

This pack is designed for a specific use. It is small, streamlined, and incredibly lightweight, and probably too specific for the majority of backpackers out there. The Lumina 45 is designed for the thru-hiker, for the folks who carry very little and travel very fast. We were excited to see a women's specific pack out there for the ultralight hiker, but also realize that this is a fairly niche market. If you are not concerned with keeping your base weight low or do not find yourself weighing the extra straps on your pack, debating whether or not to remove them, then this pack is not for you! The Osprey Eja 58 is a slightly larger, heavier option that is better suited for those who still want to go light but want to carry a bit more.

Because it is designed for such a specific use, the Lumina 45 comes at a fairly high price for a pack with a relatively small capacity. This pack is sold for $250, which is on the more expensive end of the spectrum. It is made of the lightest material on the market, while still maintaining a full frame and supportive suspension, so it makes sense that this specific of a design comes with a high price tag. If you are certain you need a pack that is this light and streamlined, then the cost of the Lumina should not be too much of a deterrent.



In the end, we liked the Osprey Lumina because of its specificity. We were happy to see that Osprey came out with an ultralight pack designed specifically with women in mind. The Lumina also has comfortable, breathable shoulder straps and hip belt, along with an innovative suspension system that is both light and functional. Though it comes at a cost, this pack is a great investment for women who are after long thru-hikes where ounces matter.
