Altaplex Overview Video with Will Wood.
Sets up with a single trekking pole adjusted to around 56"-60" (142-152
cm). Our trekking poles are long enough, or you could
add a Pole Extender to any shorter trekking pole,
add a Tent Pole, or check out our Carbon Fiber
Sets up with a minimum of 6 stakes, 10 stakes are recommended in
Either of the storm doors can be opened or closed independently.
Leave them open on nice nights for a breeze and great views. Close
the upwind door to block cold wind, or close both for 360° rain
protection. The doors are closed with custom made metal hooks. Door hooks can also be retrofitted on any
The Altaplex has steeper walls which shed snow and drain
condensation a little better than less sloped walls. This tent has
enough headroom to be pitched lower to the ground to block more
wind, dust, or snow when needed.
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.
The tarp overhangs the bathtub floor by 4-5 inches (12 cm). In
calm rain or under wet trees the 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. For even better rain protection with a door open, use the
included clips to pull the screen door back away from the rain
A Rainbow zipper gives you extra space to get in or out of the tent and gives you access to the vestibule area. The
doorway is tall for easy entry.
This tent has a solid, sewn in 8 inch (20 cm) tall bathtub floor.
The bathtub floor is a rectangle 36 inches wide by 7.5 feet long
(91 cm x 2.3 m), plenty of space for one taller person to stretch
out, or for an average sized person plus gear. You can use a full
length wide width sleeping pad with room to spare.
This tent is a good
choice for a hiker up to about 6' 6" (2 meters). If
you need extra space try
propping up the side guylines for even more headroom. The
Duplex tent is also an equally good choice for a taller hiker if
you prefer dual doors. You can sleep at a diagonal in the Duplex.
The bathtub floor has a
at both ends for storing small items like your
flashlight, glasses, phone, etc. The pockets are about 8" x 8" (20
cm x 20 cm). Older tents can be retrofitted with stick-on
Mesh Tent Pockets.
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.
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. DCF is not a particularly
noisy fabric, however almost any tent will make a little noise in the
wind. Ear plugs are not a bad idea for windy nights.

These weights are as accurate as possible. Compare carefully! Many
other manufacturers leave out seam sealing, lines, line locs, stuff sack,
stakes, etc from their weights.
- Our tents are made from Dyneema Composite Fabric. DCF has several advantages over other materials:
- DCF has a very high strength to weight ratio. The
material can handle high wind force and does not tear easily.
- DCF is inherently waterproof. There is no DWR to worry about
- DCF is not coated with any chemicals. It is PFC free.
- DCF doesn't absorb any significant amount of water.
No extra water weight to pack up.
- DCF is made from Dyneema threads which do not
stretch. The tent stays taut all night. Nylon material by
comparison can stretch and sag, especially if it gets wet.
- The seams are stitched and then taped water tight. The tie
outs have bonded reinforcements for high strength. No seam sealing necessary!
- Tape sticks well to it. Any damage can easily be fixed in
the field with our
- DCF is semi-transparent. In bright sunlight you can see a
fuzzy silhouette of a person sitting inside the tent. You cannot see any
details and it has a suitable amount of privacy for changing clothes
etc. In lower light (such as in the evening or at night) you cannot see
through at all. We also have thicker, darker DCF material
available as an upgrade that you can choose.
One nice thing about DCF is you can also see the outlines of
trees and your surroundings for a more connected outdoor experience.
- This tent has fully enclosed .7 oz/sqyd (24 g/m˛) insect screen. The holes in this screen
are super tiny, 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 DCF. This material weight is more than twice as thick as the canopy
material and is more resistant to abrasion and punctures. As with all
DCF material it is easy to patch with tape.
- Lineloc 3 adjusters are sewn to all tie outs. Bright yellow Dyneema
Z-Line cord is cut for you and included. 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

"I’ve used the Altaplex in some pretty disgusting weather,
recently on the Cape Wrath Trail, and West Highland Way. A
total of 31 days of which I was rained on for 28, much of it
overnight. I never had any rain ingress with the doors shut,
stayed completely dry and on several occasions, when I thought
it would be dry overnight (yeah, right) and didn’t even bother
securing the doors but left the front open, I still remained

Zpacks Altaplex Tent Review
"I love my new Altaplex and the switch from trekking poles to
hiking staff is a huge improvement for me. I am so glad I made
that switch and I’m also really glad I now have the perfect
tent for me! Here is a
my Camo Altaplex
just off the Tonto trail in the Grand Canyon."
"Thanks again for a great service. Here is a
picture of the
in the Scottish hills. This is on Middle Rig near
Culter Fell in Southern Scotland. Really pleased with the tent
and the Arc Blast backpack. Awesome pack, it just feels part of
you when hiking." -Robert B.
"I wanted to share a picture of my Altaplex Tent
from my recent through hike of the JMT. It was taken at 2:00 AM with Mt.
Whitney in the background." -Andrew D.
"I walked the Anglesey Coastal path in Wales in the height of
summer, so naturally the weather was appalling. It rained every
day and most nights, with occasional high winds. I kept the Altaplex storm doors open when I could and closed them when I
needed to. I was warm and dry every night, with only a small
amount of condensation on just one night. This is a marvelous
tent! It’s roomy and light, and it can handle the weather. A
very clever design. Ideal for the bigger camper, or anyone who
wants room to cook, wash, change clothes, etc. The Altaplex Tent
the star of my trip." -John D.
"I'm rapt with your stuff - great, well designed gear & I can't believe how light it is!
I had the Altaplex tent up in really strong winds - no issues. I guess when you think about it,
the standard tent used in Antarctica (the windiest place on earth) for more than 100 years is the same pyramid shape." -Peter D.
"I’ve hiked about 1/3 of the CDT so far this year. Your Altaplex tent has been working like a champ.
It took a little while to figure out how to pitch it effectively but in the last six weeks it has weathered high wind (30+ MPH),
heavy rain, hail, and snow." -Steve J.
"My Altaplex tent is still in great shape and performing wonderfully after thru-hiking the CDT, the PCT and 400 Hayduke miles!
Thanks for sending the free replacement zipper sliders, after popping those on the zipper is working perfectly again." -Jeff D.
"Since this Spring my Altaplex Tent
has covered the distance of the Hayduke Trail,
Wind River High Route, Teton Crest Trail, Beartooth Traverse, and many weekend missions in the Rockies.
I've had a couple tears in the Dyneema (small punctures in the roof and a tear or two in the floor fixed with Tenacious Tape),
but am enormously pleased with how it has performed. It has done great in the wind and rain." -Ben "Cheetah" D
"The Zpacks Altaplex finished in the top spot in this test set, thanks to its chart-topping performance in nearly every category.
The most important feature of the solo backpacking tent—its weight—is this tent’s best characteristic.
The chief limitation is the high price tag." Read the full GearInstitute Altaplex Review
