Zpacksô Duplex Flex Tent Upgrade
The Flex tent upgrade is an add-on to our normal Duplex
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
You still have the option to leave
the flex poles behind and pitch with your trekking poles to save weight on
regular backpacking trips.
Watch the Duplex Flex Tent Setup
Four 96" (245 cm)
Easton Carbon Ion poles are included. Easton's carbon fiber poles are made using proven technology, and they are
super lightweight. Just 10 ounces (283 g) for a set!
The additional hardware for connecting the poles to the tent only adds
.2 oz (5 g).
The poles will flex and bow horizontally when the wind gusts. In really windy
conditions if you can find a couple sticks or trekking poles to prop the
peaks of the tent you can keep it more rigid.
The folded length of the poles is 17" (43 cm). A tent pole sack is
included. The best way to pack them is 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 w/o sending the
Older Duplex tents can be retrofitted, see additional info below.

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

"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."

"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.
