Our Take
The ZPacks Duplex Tent is the go-to choice for gram-counters tackling long trails, coming in at just over a pound while still offering enough floor space for two wide sleeping pads.
Setup is straightforward once you get the hang of the trekking pole pitch, and the symmetrical design means less fumbling in camp after a long day.
That said, the $699 price tag stings, and you'll want to manage your ventilation carefully because condensation can be an issue.
It's a solid ultralight option for thru-hikers who prioritize weight savings, but the durability score suggests you'll need to baby it more than burlier alternatives.

What We Think
At 19 ounces, the ZPacks Duplex is the tent that convinced a generation of thru-hikers that ultralight shelters don't have to mean ultralight compromises.
It scored a 7.5 overall, with standout marks in livability and owner satisfaction, but meaningful gaps in durability that serious buyers need to weigh.
This is a tent built for people who count grams and log miles, not casual weekenders looking for a simple shelter.
User Reviews
Owner feedback on the Duplex is remarkably consistent and overwhelmingly positive, earning a 9.0 in User Reviews.
The most common praise centers on that 19-ounce Dyneema construction, which thru-hikers describe as life-changing after weeks of carrying heavier shelters.
Owners repeatedly confirm that two wide sleeping pads fit side-by-side without the squeeze you get in many ultralight two-person tents.
The symmetrical A-frame design also earns consistent praise for intuitive pitching, even from first-time trekking pole tent users.
Space & Comfort
The Duplex delivers 28.1 square feet of floor area and a 48-inch peak height, which is genuinely spacious for the ultralight category.
Four doors mean you and a tent partner aren't climbing over each other for midnight bathroom trips.
It scored an 8.0 in Space & Comfort, and the REI Co-op Flash Air 2 offers similar livability at $429 but weighs nearly a pound more, which illustrates the premium you're paying for Dyneema weight savings.
Ease of Use
The 8-10 minute setup time is honest, not marketing optimism, and owners report the pitch becomes second nature after a few tries.
If you're new to non-freestanding tents, know that you'll need stakes and good site selection, but the Duplex's symmetrical design makes the learning curve gentler than many trekking pole shelters.
It scored an 8.0 in Ease of Use.
Weather Resistance
The Dyneema Composite Fabric bathtub floor is inherently waterproof, and the screen panels at each end provide ventilation without sacrificing protection.
However, a recurring theme in owner feedback is condensation, particularly in humid conditions or when camped near water.
This is a physics problem with single-wall shelters, not a Duplex-specific flaw, but it's real and worth planning for.
It scored a 7.0 in Weather Resistance.
Quality & Durability
Here's the required honest conversation: Dyneema Composite Fabric is ultralight because it's thin, and thin means more vulnerable to punctures and abrasion than burlier materials.
The 6.0 in Quality & Durability reflects this tradeoff.
The Big Agnes String Ridge VST 1.5 weighs nearly identical at 1.2 pounds but uses more robust fabrics, making it worth considering if longevity matters more than shaving every gram.
The two-year warranty and USA manufacturing are reassuring, but careful site selection and a footprint are smart investments.
Value for Money
At $699, the Duplex is an expensive investment, and owners consistently acknowledge this in their reviews.
It scored a 7.0 in Value for Money because the price-per-ounce math only makes sense if you're logging serious trail miles.
For weekend backpackers, that $699 buys a lot of tent elsewhere.
Who It's For
The Duplex is built for committed long-distance backpackers and thru-hikers who prioritize weight savings above all else.
If you're planning a PCT or AT attempt and have already dialed in your overnight backpacking checklist, this tent makes sense.
If you need room for a third person, ZPacks makes the Triplex at $769.
The Bottom Line
The ZPacks Duplex scored a 7.5 and remains the benchmark ultralight shelter for serious thru-hikers.
The 19-ounce weight and genuine two-person livability justify the price for high-mileage backpackers.
Just know that Dyneema's weight savings come with durability tradeoffs, and condensation management is part of the deal.
