Specifically designed for ultralight backpacking and thru-hiking, the award-winning Duplex hits the sweet spot when it comes to size, weight, and features. This tent will allow you to push your limits and explore over greater distances, whether you’re finding the best route on the Pacific Crest Trail, or losing yourself in the beauty of the Swiss Alps. This tent is roomy, well-ventilated, packs down small, offers simple set up, and can be set up almost anywhere! You won’t find a lighter functional version of this tent anywhere on the market.


  • Sets up with two trekking poles adjusted to around 48" (122 cm). Slightly taller or shorter fixed length poles will also work.  If you do not use trekking poles, we have straight tent poles available, or you could consider our Freestanding Duplex Flex Tent Upgrade.  Eight stakes are required for this tent.

  • Any of the four storm doors can be opened or closed independently. Leave all four open on nice weather nights for a breeze and great views. Close the upwind doors to block cold wind, or close all four for 360° rain protection. The overlapping doors are closed with custom made metal hooks, with a toggle at the center to keep them pinned.

  • The tarp overhangs the bathtub floor by 4-5 inches (12 cm). In calm rain or under wet trees one or two doors can be left open for air flow without water dripping on the floor space. In almost all conditions at least one downwind door can be left open for air.  Tip: For even better rain protection with a door open, use the included elastic cords to pull the screen door back away from the rain spray, as shown.

  • Rainbow zippers on both sides of the tent allow easy entry regardless of which doors are closed, and they give you access to every vestibule area.

  • This tent has a solid, sewn in 8 inch (20 cm) tall bathtub floor. The bathtub floor is a rectangle 45 inches wide by 7.5 feet long (114cm x 2.3m). Plenty of space for two average people to stretch out plus space for gear at the ends of the floor.  If you are particularly tall, you might try propping up the side guylines for even more headroom. Some couples prefer the additional width in a Triplex tent.

  • Mesh pockets are conveniently located near each screen door so that they can be accessed from inside or outside the tent. They are a good place to store your cell phone, glasses, headlamp, the tent stuff sack, and spare seam tape (included). The pockets are about 8" x 8" (20 cm x 20 cm).

  • A separate groundsheet is NOT required for this shelter. The floor material is reasonably durable, and all Dyneema Composite Fabric gear can be easily patched in the field with repair tape. If you do prefer to use a groundsheet as a precaution, Flat Groundsheets are available.

  • There is screen between the bathtub floor and the walls at the ends of the tarp. An elastic cord keeps the bathtub elevated ensuring the screen slopes downwards away from the bathtub. Any condensation will run down the walls and out through the downward sloping screen, rather than onto the floor.

  • All of our tents do pretty well in the wind. The material can handle high wind loads. As long as your stakes stay in the ground (use rocks if available) your tent will stay standing. Dyneema Composite Fabric is not a particularly noisy fabric; however, almost any tent will make a little noise in the wind. Earplugs are not a bad idea for windy nights.

  • All Zpacks gear has a two year limited warranty against defects in materials or workmanship. Please see our return / warranty policy.

  • Made in the USA.

Weight:

The Duplex in the standard .51 oz/sqyd Dyneema Composite Fabric material weighs a total of 19.4 ounces (550 grams) including guy lines, sewn in linelocs, taped seams, and a stuff sack. A piece of repair tape is included with the tent.

*8x Stakes are required but are not included. We have a variety of Ultralight Stakes to choose from.

Exterior Dimensions:

Peak height: 48" (122 cm)

Ridgeline width: 53" (135 cm)

Width including vestibules: 86.5" (220 cm)

Vestibule space: 20.75" (53 cm) depth on each side

Length: 100" (254 cm)

Interior Dimensions:

Peak height: 48" (122 cm)

Floor width: 45" (114 cm)

Floor length: 7.5 feet (2.3 meters)

Zipper entry height: 36" (91 cm)

Packed Dimensions:

7" diameter by 13" tall (18 cm x 33 cm) / 520 cubic inches (8.5L)

  • Our tents are made from Dyneema Composite Fabric. DCF has several advantages over other materials:

     

    • High strength to weight ratio – the material can handle high wind force and does not tear easily.

    • Chemical free, PFC free

    • Waterproof – there is no DWR or coating to worry about wearing out. The material will not absorb significant water that will add water weight to your pack

    • Stretch-free – the tent will stay taut all night. Nylon material by comparison can stretch and sag, especially if it gets wet.

    • Taped seams – our seams are sewn for strength then taped water tight. The tie outs have bonded reinforcements for high strength. No seam sealing will be necessary!

    • Easily repairable – Any damage can easily be fixed in the field with our Dyneema Composite Fabric Repair Tape.

  • This tent is semi-transparent. In bright sunlight, a fuzzy silhouette of a person sitting inside the tent would be visible, but you cannot see any details. It has a suitable amount of privacy for changing clothes.

    In lower light (such as in the evening or at night), you cannot see through at all. We also have thicker, darker material available as an upgrade that you can choose. Another nice thing about this material is that you can see the outlines of trees and your surroundings for a more immersed outdoor experience.
  • This tent has fully enclosed .67 oz/sqyd (22.7 g/m²) insect screen. The holes in this screen are super tiny, so even the smallest insects cannot get through. Our tent screen is about 30% lighter than comparable Noseeum screen with no noticeable decrease in durability.
  • The bathtub floor is made from 1.0 oz/sqyd Dyneema Composite Fabric. This material weight is more than twice as thick as the canopy material and is more resistant to abrasion and punctures. It is also easy to patch with tape.
  • Lineloc 3 adjusters are sewn to all tie outs. Bright yellow Dyneema Z-Line cord is cut and attached for you. The yellow lines are very easy to see night or day, and Dyneema has very low stretch.
  • The expected life span of this shelter is at least one full 2500+ mile thru hike, or many years of casual use with some care.

 

.51 oz/sqyd Standard Dyneema Composite Fabric

The default canopy material choice on this tent is .51 oz/sqyd Dyneema Composite Fabric. It has high tensile strength and can handle strong winds, storms, and all the typical conditions a tent will be in. All Dyneema Composite Fabric material can easily be repaired in the field with the included repair tape if it were to get a puncture.

The material is semi-transparent, allowing you to see the silhouette of trees when looking out. In bright sunlight, you can see the fuzzy silhouette of a person when looking in, but it is opaque in low evening light.

Tensile Strength: 63 lb/in (552 N/5cm)

Puncture Strength: 
1.8 lb (8 N)

Water Resistance:
 15,000 mmH₂O

Made in the USA.



.67 oz/sqyd Dyneema Composite Fabric

This canopy material choice has the same Dyneema thread count as standard .51 oz/sqyd, but with a slightly thicker laminate that allows for a darker color or pattern to be printed on the material. The thicker laminate brings the fabric weight to .67 oz/sqyd.  It blends in to nature well. It is darker, less transparent and offers more privacy. Dyneema Composite Fabric has a bit of a sheen to it when it is new, but it dulls down significantly with some use.  

This video by John Abela shows the opacity and color of the camo fabric.  It adds around 1.0 ounces (30 grams) to the weight of the Duplex.


Tensile Strength: 63 lb/in (552 N/5cm)

Puncture Strength: 1.9 lb (8.5 N)

Water Resistance: 15,000 mmH₂O

Made in the USA.



.74 oz/sqyd Dyneema Composite Fabric


This canopy material has a higher Dyneema thread count which gives it a higher tear strength. The standard material is already difficult to tear, so this weight is unnecessary. Many thru-hikers like this feature for added peace of mind.  It is also a bit thicker and darker than the standard weight. It is less transparent and offers more privacy, but it is not as dark as .67 oz/sqyd.  It adds around 2.1 ounces (60 grams) to the weight.

Tensile Strength:
 104 lb/in (911 N/5cm)

Puncture Strength:
 3.1 lb (14 N)

Water Resistance:
 20,000 mmH₂O

Made in the USA.



1.0 oz/sqyd Dyneema Composite Fabric

Our tent floor material is made with a membrane that is more than twice as thick as our canopy material. It is more puncture and abrasion resistant. This is the standard floor material on all of our tents.


Tensile Strength:
 104 lb/in (911 N/5cm)

Puncture Strength: 3.5 lb (15.5 N)

Water Resistance: 20,000 mmH₂O

Made in the USA.

.67 oz/sqyd Ultralight Nano-Noseeum Insect Netting

Regular "No-see-um" bug netting weighs about 1 oz/sqyd. This ultralight version weighs roughly a third less without a noticeable difference in performance. It has extremely small holes which block even the smallest of insects, including mosquitoes, noseeums, etc. Nothing gets through this screen.

Cutting Guylines:

Guylines are pre-cut and attached for you. Linelocs are sewn in place for adjusting the lines. If you choose to switch out your lines for a different cord these are the default lengths:

Peaks (2x) - Cut 102 inches (259 cm) and tie a stake loop at 40 inches (102 cm). The long end attaches to the tent and the short end attaches to the door hooks.

Side Walls (cut 2x) - 54 inches (137 cm)

Corners (cut 4x) - 34 inches (86 cm).

*The two loops with rings at the peaks of the tent, and the upper loops on the side walls are used for the Duplex Flex tent poles add on.

Setup Instructions:

  1. Adjust your two trekking poles to around 48 inches (122 cm). If you expect your pole tips to sink into the ground, add a couple inches to compensate.

  2. Give your corner guylines some slack. Stake out all four corner guylines at a 45 degree angle, roughly straight off the corner points.

  3. Insert the front trekking pole outside the screen with the handle at the peak and the tip in the ground. Stake the front line.

    • If the peak is too high, tighten the front corner lines. If it is too low, loosen them.

    • The corners of the tent should be about 6-8 inches (18cm) off the ground.

  4. Insert the back trekking pole the same way and stake it out.

    • If the walls of the tent aren't smooth, you may need to reposition the corner stakes or adjust the lines tighter.

  5. Stake out the two wall tie outs.

Storm Doors:

Any of the four doors can be clipped down, or rolled up independently. The storm doors can be clipped down to the front center guylines, or rolled up depending on the weather.  Leave at least one down-wind door open for air flow unless the weather is very bad. 

Seam Sealing:

All Zpacks shelters have taped seams and bonded tie outs! No seam sealing necessary.

Best backpacking tent I have ever owned

Took my Duplex on a walk along the Offa's **** walk. The June weather was terrible, with flooding,wet ground and rain most days. The light weight was appreciated during the hill climbs, and the speed that we could get the tent up in the rain (less than 2 minutes, using trekking poles) was impressive. It is equally quick to pack up in the morning, and comes with the huge advantage that DCF doesn't absorb water, so no wet heavy fabric to worry about; we just rolled it up wet and when it came to pitch it at night we simply had to dry the inside with a small pack towel - this adds maybe a minute to the pitch time. Porch space was great for two backpacks, plenty of room for two of us to live and sleep comfortably inside (I am 6'3" tall), and - crucially - our down duvets stayed dry during some shockingly wet nights. We didn't notice a major problem with condensation inside the tent, most nights it was dry, one morning it needed a wipe when we woke as we had to pitch in a wet muddy bowl next to a river - we were expecting some condensation. If something happened to my Duplex i'd replace it with another one without hesitation.

Pull The Trigger On The Purchase of a Duplex

I have waited to post a review until I had a chance to use my Duplex a bit. I just got back from a trip and the Duplex was everything I hoped and more. My set up time was under 3 minutes and I got a perfect pitch. It even rained last night and every thing was great. If you are sitting on the fence waiting to pull the trigger on the purchase of a Duplex, just do it. You won’t regret it.

My Favorite Piece of Gear

This is by far my favorite piece of gear! Light, waterproof, comfortable, roomy and easy to set up. My two favorite aspects of this tent is the room to weight ratio and that it is waterproof and does not soak up rain like my nylon tents did. You literally just shake the tent off and rain bead off it. Then I wipe it with a mini towel. It tool me a while to purchase this tent because I was worried about condensation. I have used this tent in all conditions now. Snow camping, summer hot weather, rain and wind. The only time I have condensation is when every one in my camp party does based on surrounding conditions and weather. The benefit of the duplex with condensation is that it runs down and out the mesh on the outside of the tent and first thing when I wake up I just take a towel wipe the walls and the condensation is gone. Most of the time I have none. So don’t worry about condensation with this single wall tent. I have had no increase in condensation over my nylon tents in the past which were Big Agness Copper Spur, Nemo Hornet and Marmot Ajax. Those were all great but the DUPLEX is my favorite and exceeds my expectations. The only critique I have would be I don’t like the pockets at the side zipper entrance. So I bought their add on pocket and placed at head and foot. I bought the poles to make it freestanding if needed. I have used them with snow camping and when I camped on a rock bluff over a lake. They work good but I do prefer just using my trekking poles. Thank you Joe and team for a great tent!!!

Exceptional Design

I'm a fairly new long distance hiker with my only shelter experience being with an 8 year old MSR Hubba Hubba, so carrying and using a Duplex was astounding to put it mildly. Over my life, I've encountered a few things that, when you first look at them, you know instinctively that the design is spot-on. The Duplex is one of those things. Every aspect of it, the shape, zippers, guylines & locks, doors, toggles, support system, is thoughtfully designed for maximum efficiency and function. It is a significant investment, but you will get a high quality product that will exceed your expectations.
