The short version
The Eagle Creek Pack-It Isolate earns a Kit Score of 8.6 and our top overall slot. It is a two-cube set (Small and Medium) in 70D ocean-recycled nylon, with a dedicated compression zipper that collapses each cube to roughly one-inch depth, water-resistant fabric, and Eagle Creek's No Matter What lifetime warranty. It is the best pick if you want proven compression and a warranty that outlasts the trip. If you want the lightest set with three sizes, the Osprey UL cube set is the alternative; if you want to spend less, the Gonex 4-piece compression set is the budget call.
The Eagle Creek Pack-It Isolate is the set we recommend first in our best packing cubes guide, and it is the one most carry-on travelers should look at before anything cheaper. This review covers exactly what you get, the spec details people get wrong, and where it wins or loses against the alternatives.

Who it is for
This set fits one traveler especially well: someone packing a carry-on who wants to squeeze a few extra days of clothing into a fixed bag. The compression zipper does real work, collapsing each cube to about one inch of depth, which frees meaningful suitcase real estate without adding bulk. The semi-structured sides hold a clean rectangle in the bag, so packing stays tidy rather than turning into a loose pile. At 4.8 ounces for the pair, the system stays light enough that the weight you save in volume is not eaten back by the cubes themselves.
It is less ideal if you are packing for a longer checked-bag trip. The two-cube set covers carry-on travel well, but a full week in a large suitcase may need a second set to organize everything. If you are still deciding how to build your kit, read our one-bag travel kit guide first: it walks through how many cubes most trips actually need and where compression matters most.

The single spec people get wrong: this is a two-cube set, not a three or four-cube lineup. You get a Small and a Medium, sized for carry-on. Plan around that pair, and add a second set if you routinely check a larger bag.
Pros and cons
What it does well:
- Compression zipper drops each cube to roughly one-inch depth, freeing meaningful suitcase space rather than just organizing it.
- 70D ocean-recycled nylon is water-resistant and machine washable, and the No Matter What lifetime warranty signals real manufacturer confidence in the build.
- The two-cube set keeps total weight low (4.8 oz) and the system simple, which suits carry-on travel.
- Semi-structured sides hold a clean rectangle in the bag, so packing stays orderly under compression.
Where it falls short:
- The two-cube set covers carry-on trips well but may need a second set for longer checked-bag travel.
- Compare the current set price with the number and size of cubes you need; this set has two pieces.
How it compares
Against the Osprey UL packing cube set, the trade is compression versus pack count. The Osprey set gives you three sizes (Small, Medium, Large) and proven outdoor-brand build with YKK zippers, and it sits a few dollars cheaper, which makes it the better value if you want more cubes and do not need to squeeze volume. What it does not do is compress: owners consistently note the lack of a compression feature. The Eagle Creek gives up a third cube but wins on the one thing that matters most for a tight carry-on, collapsing your soft goods down to free real space.
Against the budget option, the Eagle Creek sits well above it on materials and warranty. The Gonex 4-piece compression set is cheaper, runs four sizes from Small to XL, and uses a double-zip compression system that genuinely works, all for under $25. The catch is the hardware: its zippers are not YKK-grade and can catch the fabric under heavy load, and the ripstop nylon, while decent for the price, is budget-tier. If you want the most cubes per dollar, the Gonex is the value pick. If you want compression backed by a lifetime warranty and a shell that holds up trip after trip, the Eagle Creek is worth the step up.
For building out a full carry-on system, our one-bag travel kit guide goes deeper on how the cubes fit alongside the rest of your gear, and the Eagle Creek Pack-It Isolate is a pick there too.

Frequently asked questions
How much does the Eagle Creek Pack-It Isolate set compress?
The dedicated compression zipper collapses each cube to roughly one-inch depth once it is loaded and cinched. That is enough to free meaningful suitcase space, which is the main reason it earns our top compression-cube slot. The listed compressed dimensions are 10 x 7 x 1 inches for the Small and 14 x 10 x 1 inches for the Medium. Actual packed depth depends on the contents.
Is the Eagle Creek Pack-It Isolate worth it?
For carry-on travelers, yes. It earns our highest packing-cube Kit Score (8.6) because it combines effective compression, water-resistant 70D ocean-recycled nylon, a clean structured pack shape, and Eagle Creek's No Matter What lifetime warranty. The main reasons to spend less are if you do not need compression or if you want more cubes per dollar.
How many cubes come in the set?
Two: a Small and a Medium. That pair is sized for carry-on travel and keeps the total weight to about 4.8 ounces. If you regularly check a larger bag, plan to add a second set so every category has a cube.
Can you wash the Eagle Creek Pack-It Isolate cubes?
Eagle Creek specifies a gentle machine wash and flat drying. Follow the care label. Its No Matter What warranty covers defects under the published terms, not every kind of damage.
Eagle Creek Pack-It Isolate vs Osprey UL: which is better?
The Osprey UL set gives you three sizes and a slightly lower price, which makes it the better choice if you want more cubes and do not need compression. The Eagle Creek Pack-It Isolate compresses to free real suitcase space and is backed by a lifetime warranty, which makes it the better pick for a tight carry-on where volume is the constraint.
