Summary

This tent provides amazing space and livability in an ultralight package. It provides everything tents weighing three times as much do without really sacrificing anything. Very impressive.

Pros

  • Ultralight weight
  • Livability
  • Tight pitch when done well

Cons

  • High price
  • Not free-standing (but there is now that option)

The Zpacks duplex is a two-person single-wall cuben fiber (now Dyneema?) shelter that weighs about 22 oz (without stakes or poles—but with all guylines). The amount of room you get for a tent this light is pretty amazing. It is a two-man tent - an like most ultralight two person tents, it would be a tight fit for two big guys. But it makes a palace-like solo tent at a weight that many other very small solo tents cannot match.

It is essentially a tarp-tent design that has a bathtub floor attached to the tarp by lightweight mosquito netting—so you are fully protected from bugs. Amazingly, it provides two doors at this weight, with zippered bug netting entrances on each side along with zipperless vestibule doors. The doors halves are designed so they overlap and are closed at the bottom with a clever little hook device and halfway up with a toggle and loop closure. I haven't been in the rain with it yet, but the doors look like they would be pretty weather tight if the tent was set up correctly and the closures were tight.

It is a basic A frame design using trekking poles. The tarp part hangs at least four inches past the bathtub floor all around, providing plenty of coverage for bad weather. You can lower the pole height to lower the pitch to provide a more weather resistant pitch, but I don't think that would be necessary unless it was a super windy storm. And because it is a single wall design, ventilation is important. I had no issues with condensation in temps ranging from 22 to 37 at night.

The tent is very "livable". It is bright—partly due to the almost translucent nature of the material—it lets in a lot of light. If you follow the pitching instructions, the center height is about 48 inches, so when you sit up in the center of the tent you have plenty of headroom. The bathtub floor is a little strange compared to a conventional tent design—because the floor itself is not really staked out—only the tarp top and door/vestibules are staked. Before you get your gear into the tent to weigh down the floor it can kind of billow around in the breeze. This is absolutely harmless, but is kind of weird at first.

The construction is top quality, with reinforcements everywhere they are needed. It comes with six guylines—for all the staking points—that have tensioners attached. I found the tensioners a little hard to operate with one hand. I almost always had to use two hands. But they seem very sturdy. Same thing goes for the screen door zippers - because of their lightness they pretty much require two handed operation.

The tent requires six stakes or anchors. There is no getting around that. You don't have the convenience of a freestanding tent. BUT Zpacks now offers a two pole set that makes the tent free-standing for folks that don't use trekking poles or who just prefer that convenience and don't care about the extra weight.

The newer versions have the loops required for the poles and I think Zpacks will retrofit previous models with the loops. The freestanding version has two long, crossing poles, that I would assume still require staking, but allow you to easily move the tent around and open up the full entry to the doors that are normally split in half by the trekking pole setup design. Pretty cool.

A really great feature (benefit) of cuben fiber for tents is that it does not absorb moisture like a silnylon material. You know how on cold mountain mornings your tent fly will be wet on the outside and you have to spend some time during the day drying it out? Never happens with cuben fiber because the material itself is waterproof so there is not a layer that absorbs moisture. I love that about the stuff and in my opinion that is something that makes it ideal for tents.

The floor is a heavier weight material and it seems to stand up to abuse very well. I've spent 11 nights in it so far and I never use a groundcloth. The other really great thing about cuben fiber is how easy it is to repair. Just slap some cuben fiber tape on a tear and it is about as good as new.

Of course, this tent is pretty pricey. That's the cost of going ultralight. But you are supporting a U.S. handmade product and it is an excellent product in design and execution, that's for sure. And Zpacks is well known for its personal service.

Of course it comes with a cuben fiber stuff sack and packs down pretty small. Because of the "crinkly" nature of cuben fiber, it seems a little bulky, but when you stuff it in your pack it crushes down really well.

One word of caution, I know the video on the website shows a guy they say is 6'6" in the tent, but I am 6'2" and when I am in a 20-degree sleeping bag I come close to touching the ends. I think I have about two inches to spare on each end. I think if you are 6'4" you are almost too tall unless you are solo and can sleep diagonally. For normal sized people the tent is plenty big for two, and really big for one.

All in all, if you want a great, versatile shelter that really is ultralight and you don't mind spending the extra money, I think you will be very happy with the Zpacks Duplex. Great design!

Great review of your ZPacks tent, Paul! Thanks for taking the time to post it. If you have any pictures of yours in use you could show others in your review, that would be great.

Thanks for your review. It's great lightweight shelter, probably one of the best on market. Is it made as a single piece, without dividing to inner tent and rainfly? Also it worth noting that there are straight carbon poles available for those who don't use the trekking poles. They are 2 times lighter and cheaper that freestanding kit.

Sounds like a great UL tent. Thanks for posting.

Vladimir, this isn't a double-wall shelter, it only has a tarp (the "rainfly"), a bathtub floor, and netting that covers the door ends and the gaps on the sides between tarp and floor.

Thanks, Paul, for stating my opinion also! Bought the " camouflage " version about six months ago, and love it! Super easy to set up and plenty of room for one. The Camouflage lets in less light for only a fraction more weight, and more privacy. One thing some folks don't know, is you can monitor ZPacks website for their " Bargain Bin." I bought my Duplex there for $50 less, because of some minor imperfections, which was a minor patched flaw in one area. Worked perfect, and saved some money. I have the carbon tent poles, since I don't use trekking poles, and they work great! Only problem for interested folks, is that you can't adjust the carbon poles like a trekking pole: this was a problem in Yosemite at the Backpacker's Camp, with hard packed dirt on an uneven tent site. I had to scoop out the ground on one side and slide the pole into a makeshift hole, but worked fine. I've spent four days in rain: one in a hail storm in Yosemite this last July, and the tent is amazing in waterproofness and the ability to keep the door open because of the overlap of the roof. Glad you like!

Rating: rated 4.5 of 5 stars

Summary

Overall it is a great tent—roomy, light, and comfortable both in the desert and above 12,000 feet. Sturdy when pitched well and stands up to storms (though you will notice tiny micro-holes appearing after moderate use). I used this tent for six months (April-September) while hiking the PCT, and I'd make the same tent choice again.

Pros

  • Ultralight
  • Compact
  • Comfortable for two people (a castle for one)
  • Keeps you dry

Cons

  • Micro holes appear after moderate use
  • Guyline exterior can rip if rocks are needed to pitch tent
  • Very expensive
  • Sleeps cold during shoulder seasons

Is it worth the money?! Yes—IF you plan on getting A LOT of use out of it, or if lowering your base weight is very important to you. Both were true for me and I really liked this tent.

Comfort: Very comfortable for one person—comfortable for two with room to store gear in vestibules if storm doors are closed. I am 5'9" and it was plenty long enough for me. I bet if you are much taller than 6'2" or 6'3" you will run into issues with you head or foot box of your sleeping bag getting wet from touching the slopped roof of tent. 

Setup: Easy to set up after you get the hang of it. Only six guylines are needed for a great pitch. If you have never used a non-free standing tent before, your first few attempts may be uneven/less than perfect pitches, but small adjustments to a pitched Duplex often do the trick.

If you are camping on hard rock or on soft soil, rocks can be used to fix guylines instead of stakes, however if you are using rocks during a storm or windy conditions the guylines can begin to fray due to friction from movement against the rocks.

Stability: Very stable. I put this tent through extreme wind, rain, and two inches of snow accumulation and it never fell.

Whether Resistant: The ultralight nature of this tent, means you sacrifice a little bit of durability—this is demonstrated in the micro-holes that will (definitely) appear in the roof of the tent (especially near joints), however they are easily patched with the supplied Dyneema Composite Fabric repair tape or other sturdy tapes.

The bathtub floor does well to keep out rain and pooling water during storms. If pitched improperly there may be a gap in the vestibule doors where they clip together, resulting in some rain/snowfall inside the vestibule. It dries quickly in the sun and wind.

Ventilation: Excellent. The two large mesh sides, mesh above the bathtub floor and four doors allow for great cross ventilation, and you can choose your level of air flow v. warmth from closed doors. Of course if you are camping in a low-lying area near water, you'll get condensation. Because there is so much mesh, and the materials are light, it sleeps cold during the shoulder seasons—October is chilly in a Duplex if you are in a colder climate or in inclement weather.

Packability: Excellent. You can ruff stuff it into your pack or fold and roll it up so it is just larger than a nalgene water bottle. And no tent poles to pack :)

Ease of Use: Easy peasy. It's a simple tent with no frills so what you see is what you get.

Construction & Durability: For an ultralight tent, it does pretty well under heavy use. I mentioned the guyline and micro-hole issue above, outside of those issues it does well for a tent made of ultralight materials. After six moths of use I plan on getting a few more years of smaller trips out of it!

Conditions: I used this tent every night for six months in the desert, the high Sierra, and in inclement weather on the border of Canada. I plan to continue using it between the months of April-September. I'd find a different tent for late fall through very early spring.

I appreciated the photos Christine. Always nice to add a little perspective. Any tent that is easy-peasy to set up is favorable in my book!

These shelters are pretty amazing when you consider they weigh 21 ounces in the .51 oz DCF version. I have the .74 oz and it is 24 ounces total weight. I think 26 ounces when I add in the six stakes.

Summary

The ultimate three-season, two-person backpacking shelter.

Pros

  • Lightweight
  • Waterproof
  • Very roomy
  • Livable
  • Easy to pitch
  • Strong

Cons

  • Cost

This is a ridiculously nice shelter. It's really easy to set up, uses 6 to 8 stakes for a taut pitch. It's very stable in wind and hard rain, the bathtub floor stands up to streams flowing under you (don't pitch it in a stream bed...).

There is great ventilation, room for two and a 60-lb dog easily. It is easy to pack up small. All in all it's just fantastic if you can get past the price. One month's rent for a tent is quite a bit, but I absolutely love it so far.
