Zpacksô Duplex Flex Tent Upgrade


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 bike packing, canoe trips, or car camping.

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


Ordering a new tent:

Add a normal Duplex Tent to your cart, then add the poles and hardware here. The normal tent lead time applies.

What's Included:
4x Flex tent poles with 4x rings, 2x toggles, stuff sack - $125

Retrofitting an older tent:

If you would like to update an older Duplex tent produced before 11/15/15 you will have to send it in to us to sew on the required attachment points and add hardware. This includes adding the attachments to the tent for the poles, adding Lineloc 3 adjusters to your tie outs, updating your guy lines to 2mm cord to fit the Linelocs, and return shipping. This does not include poles. Add the pole kit above to your cart too.

If you order this we will email you our address and instructions to send the tent in. Retrofits are usually completed within a week or two. Let us know when you order if you have a return due date.

**If your tent already has loops on the walls, and loops at the peak (but no metal rings at the peak) you do not need to send your tent in. Rings can be tied on at the peaks. Please order the poles above and email us for extra rings.

"My Free-Standing Duplex Flex Tent worked great on my Arizona Trail section hike. It even got christened with some overnight hail and rain at 6000 feet." -Robert H.
"We have just come back from a trip to Iceland, the maiden voyage for our Duplex free standing tent. Overall it functioned great. Would bring it again. The freestanding poles allowed for more placement flexibility which was helpful for stake-unfriendly soils as well as for swift adjustments/adaptations to local site-irregularities in the harsh volcanic Icelandic conditions. The good air flow and dual entries were much appreciated. Although tent-integrity never appeared threathened, glacier-plain wind forces made the poles flex horizontally a fair bit (good thing, no breakage risk). -Gerrit B.
"I love your gear, the Duplex tent is unreal especially with the free standing poles, made it very easy to find the perfect spot to sleep :)." -Devlin G.
"I have a tent problem: I canít stop buying them. Iíve been tempted by Zpacks tents for a long time, but was able to resist since I have an aversion to non-freestanding tents. Then your Duplex Flex came along. Itís still amazingly light with the poles (1.5lbs lighter than my previous, smaller solo tent). Itís like Doctor Whoís TARDISÖ somehow bigger on the inside than on the outside. Itís huge in there! I may be able to stop buying tents now. Iíve found the ultimate shelter. Hereís a picture of my Duplex Flex in Dolly Sods, Monongahela National Forest, West Virginia." -Shannon
"Just used my new Duplex Flex tent on a hike and really love it. You really have designed the best lightweight tent on the market. The freestanding tent pole setup really suits coastal hiking in Australia." -Rick V.
"Great designs Ö really forward thinking with the uses of Cuben Fiber in products. I personally think the Duplex Flex Tent Upgrade is brilliant. I was on a tent innovation committee with a mainstream company a few years back (I did a bunch of photography for them, and they invited me to participate), and I asked why something like what you did wouldn't work to turn some of their new tent designs to be free standing with added poles (when one doesnít want to use trekking poles and when free standing is needed), I was told it was imposible. Clearly you had the wisdom to make it work, and matched it with a beautiful tent design." -Dave S.,
"I ordered the Duplex Flex, and took it out for a long weekend test. The tent is great, gusts over 40MPH and the tent barely budged. We kept asking ourselves what we forgot at home, our normally light packs seemed unreasonably light with a shared quilt and an insanely light tent." -Dave S.
"Here is a photo of the Duplex Flex that I took while camping recently in Portugal. We love the everything about the tent and couldn't be happier! We are in Spain now and will surely be posting more pictures of the tent during our two year cycling tour." -Steve C.
