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.

- 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.
.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

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) - 32 inches (81 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.
- 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.
- Give your corner guylines some slack. Stake out all four corner guylines at a 45 degree angle, roughly straight off the corner points.
- 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.
- 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.
- Stake out the two wall tie outs.
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.
All Zpacks shelters have taped seams and bonded tie outs! No seam sealing necessary.
I'm really happy with the tent and looking forward to using it outdoor! The delivery was fast and customer service was excellent! Thanks!
Good ultralite pack.
I like the pack. I own 3 Hyperlite packs and this is a good, less expensive alternative.
Triple Crown tent
This is my second one. First is still in great shape but about to be a Triple Crowner.
Just what I'd hoped it would be
Love this tent, its super light, easy to set and drop, and roomy. I'm looking forward to spending a lot more nights in it.
