Our Flex Kit allows you to transform our standard Duplex Tent into a freestanding palace.  Simply install the hardware and attach the Flex poles and you're good to go. Freestanding poles make pitching your tent easy on packed down campsites and locations where staking is difficult.

The Flex tent upgrade is an add-on to our normal Duplex Tent that allows it to be pitched with freestanding tent poles. It can be set up with zero stakes in calm conditions, or with just 2 stakes if you want to use the vestibules. It is not necessary to stake the corners or side walls except in extreme weather.

Freestanding tents are convenient in situations where stakes are difficult to use. They make it easier to pitch on beach sand, snow, or on rocky or compacted terrain. You can set up on a tent platform, or other suboptimal locations without struggling with stakes. Flex poles are also handy on trips when you don't have trekking poles, for example bikepacking, canoe trips, or car camping.

The poles also lift the side walls of the tent outward for more interior space, which is especially valuable for tall hikers.

You still have the option to leave the flex poles behind and pitch with your trekking poles to save weight on regular backpacking trips.

The poles will flex and bow horizontally when the wind gusts. In very windy conditions, you should use sticks or trekking poles to prop the peaks of the tent to create a very rigid shelter.

  • Four 90" (229 cm) Easton Carbon 3.9 poles are included. Easton's carbon fiber poles are made using proven technology, and they are super lightweight.

  • The Dyneema® Composite Fabric material stuff sack and hardware for connecting them to the tent are included in the price and weight.

  • The folded length of the poles is 19.25" (49 cm). A tent pole sack is included. The best way to pack them is to stand them in your pack's side pocket or tuck them inside your pack vertically.

  • Any new Duplex tents made in 2016 and later include attachment points for the Flex upgrade, and poles can be added at a later date without sending the tent in.

  • 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.

Duplex Flex Instructions

Click here for a printable version.

If you have purchased the optional Flex tent pole kit you should have 4x 90" (229 cm) tent poles, 4x metal rings, 2x toggles, and a tent pole sack.

Setup Instructions:

  1. Untie each of the four corner stake loops, and re-tie the loops the same way but with a ring attached.

  2. Loop each of the two toggles on to the two wall tie outs on the tent.

  3. 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.

  4. Cinch the corner guy line to give the pole some flex and keeping it snugly in place.

  5. Insert the other three tent poles in the same fashion.

  6. 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.

  7. 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.

  8. In very windy conditions you can get a more solid pitch by using sticks or trekking poles to brace the peaks of the tent.

Awesome kit!

This kit not only does what it should, but it actually (I would argue) does it better than many inherently-freestanding tent models. When you get the tent fully rigged with the poles, you can actually grasp both walls and fold the tent over kind of like an envelope or a halved piece of paper! Makes it easier to move than most freestanding tents, in that it’s a more compact carry... and I welcome any opportunity to reduce the chances of snags!

Well thought out, well designed tent and poles. Probably the best, certainly the lightest, 2-person tent I've owned. Superb customers service and care.

Kept me dry in the rain at the Grand Canyon!

The poles are a wonderful addition to the tent, especially in rocky and heavily impacted campsites at Grand Canyon locations like Clear Creek and Bright Angel Campground: the tent stood up on its own with no problem, and the bathtub bottom stayed high enough to keep me dry even on the night when it rained and it turned out I had pitched my tent in a puddle. The only snag was that I really should have read the instructions first, as I didn't know where to attach the toggles; but now that I'm home and have reviewed the setup video, I should have no problem the next time I'm out. Great product, and I didn't even notice the weight!
