Osprey makes backpacks people trust for decades, so an ultralight packing cube from them isn't a random accessory — it's made by a company that treats every gram as the enemy. That focus shows. These cubes use nano-ripstop that weighs a fraction of standard cube fabric, and they pack down to almost nothing when empty. If you carry your bag on your back and count weight, that's the whole pitch, and Osprey delivers it about as well as anyone.
Ultralight, and what that actually means
A standard cube adds a few ounces of fabric and zipper each; across a full kit that's real weight you carry all day. Osprey's nano-ripstop shaves most of it off. The trade-off is honest and unavoidable: thin, light fabric is less abrasion-resistant than heavy fabric. For a careful one-bag traveler that's a non-issue; for someone who drags a pack across gravel and stuffs it past full, a sturdier cube lasts longer. That's why the weight score is a 9 and the build a 7 — genuinely good for the fabric class, but not a tank.
No compression — and why that's fine here
Osprey's ultralight cubes skip a compression zipper, which is the right call for the job: a compression zipper adds weight, and the whole point of this set is to have none to spare. If you need to reclaim space, that's a different tool — a compression set — and you accept the extra grams for it. Trying to get both the lightest cube and real compression in one product usually means compromising both.
Where it fits: one-bag and backpacking
These are backpack cubes. A top-loading pack rewards low weight and findability, and light cubes that pack down small suit it perfectly. If you're building a one-bag kit, this set sits right at the top of our backpacking roundup and our ultralight roundup. For a roller-bag traveler who doesn't carry weight, the durability trade tilts the other way — a standard set makes more sense.
Who should buy it
One-bag and backpack travelers who count grams and treat their gear with reasonable care. If you want maximum durability, or compression, look elsewhere — but for pure weight-to- organization, Osprey is hard to beat.
