At $700, the Osprey UNLTD packs in a heap of features and technology. But who should buy it, and why?
Regarding backpacks, I tend to be a bit of a minimalist. I like a big, open sack with a light but strong frame and a couple of organizational features.
So in looking at Osprey’s UNLTD, I’m coming from the perspective of a hopeful skeptic. I like the idea of a truly dialed backpacking pack, but am dubious about all the bells and whistles. Would this wildly complicated backpack enhance my experience on the trail?
After testing the pack on a few outings, I have split feelings about it. For some, this pack will be a godsend. For others, it’s simply overkill, with features that you won’t use that add too much weight. Read on to learn more.
In short: The Osprey UNLTD is one of the most technologically advanced backpacks ever made. It has an incredibly comfortable 3D-printed back panel that results in bespoke fitting. And it has many organizational and comfort features. But these come with a heavy weight and a very hefty price tag that force the UNLTD into the realm of a niche product.
Osprey UNLTD Backpack Features

The UNLTD is packed with more technology than any backpack I’ve used. And with a sky-high price tag, it should. I like to compare it with a luxury SUV. It’s heavy, cushy, and comes with industry-topping creature comforts. I know it’s an odd way to look at a backpack, but it feels fitting.
Let’s start with the star of the show, the 3D-printed lumbar support. Osprey officially calls it the “3D-printed Fitscape lumbar support with Carbon DLS technology.” This honeycomb of 3D-printed material has both visual and tactile appeal.
When wearing the pack, it sits across your lumbar on the user’s lower back. It provides an extremely airy contact point that is both pliable and supportive. Even with quite a decent load, it feels really nice.
Moving up the back, you get Osprey’s Antigravity Mesh back panel, in this case, called Airscape. This supports the pack away from the user’s back while allowing airflow. I tested the pack in some very hot conditions at the Great Sand Dunes National Park and noted that my back stayed dry and cool even while hauling lots of gear for sandboarding up the tall dunes.
