Duplex Freestanding Flex Kit
This kit not only does what it should, but it actually (I would argue) does it better than many inherently-freestanding tent models.
Transform your Duplex Classic, or Duplex Pro tent into a freestanding ultralight tent for when stakes aren’t an option. Our Flex Kit is perfect for platform camping on the Overland Track or in the White Mountains, or for packed down campsites along the John Muir Trail. The poles fold up short, which is perfect for bike packing and smaller backpacks.
The Flex Kit is like owning two ultralight tents in one. Simply install the hardware and attach the lightweight Flex poles to your Duplex and you're good to go.
Now available in Ultralight Carbon Fiber, or Aluminum. Both styles have comparable flexibility, durability, and overall performance. Choose Carbon to go as light as possible, or Aluminum for a slightly shorter folded length and more economic option.
*TENT NOT INCLUDED
*The Duplex Flex Kit is only compatible with our Duplex Classic, Duplex Pro, and Duplex Zip tents manufactured in 2016 or later. If you have an older tent please make sure it has 2x rings sewn at each peak or it is not compatible.

- Fits the Duplex Classic or Duplex Pro tents.
- Pitch on beach sand, granite, tent platforms, packed down car-camping tent sites and other places where stakes are tricky.
- Fast, easy setup. The four poles slip into rings at the peaks and corners of the tent, and there is a toggle at the center.
- Use trekking poles, or 48" tent poles to brace the peaks in high wind. The Flex poles can be used alone in moderate weather, but they will bow and flex in high wind if the peaks aren't braced.
- Combining Flex poles and Trekking poles creates a very rigid shelter that is stronger in high winds compared to either style alone.
- Compact folded size allows the poles to roll up with your tent. Great for bike-packing and small backpacks.
- Flex poles lift out your tent walls, adding more head and foot room relative to trekking poles alone.
- Leave your Flex poles at home on ultralight backpacking trips when they aren't needed, or add them for tricky conditions or trips where ounces aren't as critical.
- Attachment hardware and a Dyneema Composite Fabric stuff sack are included in the price and weight.
- All Zpacks gear has a two-year limited warranty against defects in materials or workmanship.
Choose from Easton Carbon 3.9 poles, or Aluminum.
Carbon Poles: Four 91.25" (232 cm) poles with 8 sections each. Folded length 12.5" (31.75 cm).
Aluminum Poles: Four 91.5" (232.4 cm) poles with 9 section each. Folded length 11.25" (28.5 cm).
The folded/packed girth is about 2.5" (6.4 cm). The Duplex tent stuff sack is large enough to accommodate the poles rolled up with the tent for convenient packing.
A Dyneema® Composite Fabric tent pole sack (about .2 oz) and hardware for connecting the poles to the tent (about .2 oz) are included in the total price and weight shown.

Duplex Flex Instructions

If you have purchased the optional Flex tent pole kit you should have 4x 91.25" (232 cm) tent poles, 4x metal rings, 2x toggles, and a tent pole sack.
Setup Instructions:
- Untie each of the four corner stake loops, and re-tie the loops the same way but with a ring attached.
- Loop each of the two toggles on to the two wall tie outs on the tent.
- Insert a tent pole diagonally such that one end is through a metal ring at the peak, and the other end is through the metal ring at the opposite corner guy line.
- Cinch the corner guy line to give the pole some flex and keep it snugly in place.
- Insert the other three tent poles in the same fashion.
- Attach the toggle around the center of the X formed by the tent poles. The poles should have a moderate amount of flex so that the wall is pulled outward.
- In calm weather no stakes are necessary. If you wish to use the vestibules stake out the front and back door stakes. In moderate weather stake the two wall guy lines to keep the tent anchored. In extreme weather all eight stakes can be used including the corners.
- In very windy conditions you can get a more solid pitch by using sticks or trekking poles to brace the peaks of the tent.
