The ideal ultralight tent for hikers up to 6’6”, the Altaplex is the perfect place to wait out the rain on the Appalachian Trail or to recover after a long day of bushwhacking.
Specifically designed for taller backpackers and thru-hikers, this lightweight tent provides ample head and foot room while still easily pitching with a single trekking pole.
A great fit whether you are a triple-crowner or just out for a weekend in the Smokies. This tent is roomy, well-ventilated, packs down small, can be pitched quickly, and can be set up in the tightest of spaces. Tall hikers won’t find a lighter tent with this much space anywhere on the market.
An optional flat groundsheet is available for added protection here.
Sets up with a single trekking pole adjusted to around 56"-60" (142-152 cm). If your trekking poles do not extended to 56" (142cm), you can add one of our trekking pole jacks to increase the height or considering using one of our Carbon Fiber Staffs.
- Sets up with a minimum of 6 stakes but 10 stakes are recommended in windy conditions.
The storm doors can be opened or closed independently. Leave one or two doors open in nice weather for a breeze and great views. Close the upwind door to block cold wind, or close both for 360° rain protection. The overlapping doors are closed with custom made metal hooks, with a toggle at the center to keep them pinned.
The canopy overhangs the bathtub floor and the screen doors by 4-5 inches (12 cm). In calm rain or under dripping 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 elastic cords to pull the screen door back away from the rain spray as seen in the photo gallery.
A single closed door creates enough vestibule space for storing a wet backpack or muddy shoes, if you don't want to bring them into the tent.
There is screen between the bathtub floor and the walls around the perimeter. An elastic cord keeps the bathtub elevated, ensuring the screen slopes downwards away from the bathtub. Any condensation, which single wall shelters may experience, will run down the walls and out through the downward sloping screen, rather than onto the floor.

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 36 inches (91 cm) wide. The floor is 7.5 feet (2.3 meters) long. There is plenty of space to stretch out, with room for your gear beside you or at the ends of the floor.
A Mesh pocket is conveniently located near the door so that it can be accessed from inside or outside the tent. It is a good place to store your cell phone, glasses, headlamp, the tent stuff sack, and spare seam tape (included). The pocket is about 8" x 8" (20 cm x 20 cm).
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. 60 mph (100 km/h) gusts are no problem. The material can handle high wind loads, and as long as your stakes stay in the ground (use rocks if available) your tent will stay standing. Dyneema® Composite Fabric is not particularly noisy, however almost any tent will make a little noise in the wind. Earplugs are not a bad idea for windy nights.
This tent rolls up to about 6" x 12" (15 x 30 cm). It is a loose fit in an included Medium-Plus size stuff sack which is 7" x 13" (18 x 33 cm).
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.

- Our tents are made from Dyneema® Composite Fabric. Dyneema® Composite Fabric has several advantages over other materials:
High strength to weight ratio – the material can handle high wind force and does not tear easily.
Chemical free, PFC free
Waterproof – there is no DWR or coating to worry about wearing out. The material will not absorb significant water that will add water weight to your pack
Stretch-free – the tent will stay taut all night. Nylon material by comparison can stretch and sag, especially if it gets wet.
Taped seams – our seams are sewn for strength then taped water tight. The tie outs have bonded reinforcements for high strength. No seam sealing will be necessary!
Easily repairable – Any damage can easily be fixed in the field with our Dyneema® Composite Fabric Repair Tape.
- This tent is semi-transparent. In bright sunlight, a fuzzy silhouette of a person sitting inside the tent would be visible, but you cannot see any details. It has a suitable amount of privacy for changing clothes.
In lower light (such as in the evening or at night), you cannot see through at all. We also have thicker, darker material available as an upgrade that you can choose. Another nice thing about this material is that you can see the outlines of trees and your surroundings for a more immersed outdoor experience.
- This tent has fully enclosed .67 oz/sqyd (22.7 g/m²) insect screen. The holes in this screen are super tiny, so 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 Dyneema® Composite Fabric. This material weight is more than twice as thick as the canopy material and is more resistant to abrasion and punctures. It is also easy to patch with tape.
- Lineloc V adjusters are sewn to all tie outs. Bright yellow 2.0mm Dyneema® Z-Line cord is cut and attached for you. 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 care.

Guylines are pre-cut and attached for you. Linelocs are sewn in place for adjusting the lines. If you choose to switch out your lines for a different cord these are the default lengths:
Peaks - Cut 102 inches (259 cm) and tie a stake loop at 40 inches (102 cm). The long end attaches to the tent and the short end attaches to the door hooks.
Side Walls (cut 4x) - 54 inches (137 cm)
Corners (cut 4x) - 32 inches (81 cm).
- Adjust your trekking pole to around 56 to 58 inches (147 cm). If you expect your pole tips to sink into the ground, add a couple inches to compensate.
- Give your corner guylines some slack. Stake out all four corner guylines at a 45 degree angle, roughly straight off the corner points.
- Insert the trekking pole outside the screen with the handle at the peak and the tip in the ground. Stake the front line.
- If the peak is too high, tighten the front corner lines. If it is too low, loosen them.
- The corners of the tent should be about 6-8 inches (18cm) off the ground.
- If the walls of the tent aren't smooth, you may need to reposition the corner stakes or adjust the lines tighter.
Both of the doors can be clipped down, or rolled up independently. The storm doors can be clipped down to the front center guylines, or rolled up depending on the weather. Leave at least one down-wind door open for air flow unless the weather is very bad.
All Zpacks shelters have taped seams and bonded tie outs! No seam sealing necessary.

Loving the Altraplex. I practiced setting it up around 6 times and have mastered that. I am excited to have a tent that is waterproof, I can sit up in and weights less than a pound. I bikepack and keeping my over all weight low is crucial to successful bikepacking adventures. Thanks ZPacks.
Very nice, lightweight, and expensive tent. I was torn between this tent and the Duplex, but I am happy that I went with this one. The steep pitch allows for noticeably more headroom (and footroom) than the Duplex (my friend has one). While the Duplex appears to be much bigger on the outside (dual vestibules), it really is not that much wider on the inside (ok, 9"). I can still fit all of my gear, inside this tent along with my "normal-sized" pad. I use two regular MSR Groundhog stakes for the front and back of the ridge line and then mini-Groundhogs for everything else. You can set it up with 6 stakes, but I use 8 to help increase the head/foot room a little more. Ten stakes can be used, but is probably overkill in most conditions. It does take some practice to set it up properly and the included instructions were not entirely clear on the best way. I watched a video by darwinonthetrail ("how to get the perfect pitch") and it was extremely helpful in getting the tent set up properly. I use the CNOC trekking pole and it works very well. I also "slept" for at least a few hours with one of the doors rolled up, while it was raining - straight down. It did a surprisingly good job of keeping water out of the tent because of the slight canopy overhang. Once the wind picked up and it started raining harder, I started to get some splash and easily dropped the door down for better protection. The door set-up is novel, but it works and I haven't really missed having a zipper. Condensation has been mild so far. Really, an excellent tent for a premium price, but so far I'd say that it's worth it.
Definitely a learning curve switching from a double wall tent w/ poles to an ultralight single wall. First week in backcountry it performed beautifully. Stayed dry thru rain, wind, and hail storms. Still learning the condensation/ventilation conundrum but small no problem. This is one excellent piece of hiker kit for a tall hiker. Thanks, Zpack
AN ABSOLUTE OUTPERFORMING SOLO LIGHTWEIGHT TENT. But I get ahead of myself. First, some context. I grew up in Fairbanks, Alaska, in the woods. Camped in central Alaska as a child, son of an outdoor adventurer. As a young adult, I solo hiked in Denali, camped in Thailand, and camped my way across the lower 48 states. Now in my 50's, I rock climb and actively camp and hike outdoors. Four trips to the Wind Rivers in Wyoming. Ten canoe trips in central Alaska wilderness. Climbed Rainier. Climbed the Grand Teton. Hiked short stretches of the A.T. Winter camped in the New Hampshire and Vermont hills. Camped in the Florida Everglades, Joshua Tree, Big Bend National Park, the Grand Canyon -- the list goes on and on. So, when I recommend gear, I come at it with some experience. At this point I have more gear failure experiences than grey hairs in my beard. I am one of those gear hounds. The price doesn't stop me -- the quality of the gear is all I care about. When it comes to tents, I have tried North Face, REI, and everything in between. My current tent inventory is about ten in total, but I have probably tried about 20+ tents in my day. And while there are some "good" tents out there, from a variety of brands, for me it all boils down to two makers, each for different applications. One of them is Hilleberg who make heavier but truly BOMBER tents for winter expeditions and take-a-beating three season trips. I know this is a Zpacks review, but I have to make a short call out to Hilleberg -- they are the real deal. The other tent maker that I now trust is Zpacks. My Altaplex weighs in at a pound and does the work of most five pound tents -- in fact, it outperforms all but the very best of my five pound tents! I just got out from a streak of Wind River hiking with my Altaplex, and it is a true performer. Set up was FAST and worked well in a variety of settings. Interior space is totally solid for my 6'1" frame. It withstood 30 mph winds with buckets of sideways rain. I woke up one morning in a giant overnight-formed puddle an inch deep and there was ZERO sign of water in the tent. The material is waterproof, and I mean totally waterproof. The ventilation was super and never got condensation. The tension system worked perfectly. I was skeptical of the door system, but, hey, it REALLY worked for me. It blew, rained, snowed lightly, and blew harder. I worried about my food supply, whether my headlamp batteries would hold out and whether my InReach Mini would get a signal -- but I NEVER had to worry about the tent system. It rocked. Would I want more in a tent? Sure, but not at this weight class. I would love bigger and more pockets. And more attachment points for 50 mph winds. But that is NOT what this tent is. This is a go-light, go-fast tent -- and in that category this thing is vastly superior to the competition. So, if you are looking for a super solid solo tent for all but the worst conditions (and by really bad conditions, I am referring to winds over 45 or 50 mph and serious snow conditions or truly constant tropical downpours) this is the tent for you. If you have those other conditions on your trip plan, look up the Hilleberg Saivo and know you will never be forced back to base camp or to your car or motel! Forget the price tag, and pony up for the Altaplex. You won't regret it. I already have the two person version on order for trips with my climbing buddy. Zpacks rocks!
This is my first Zpacks shelter, the Altaplex in olive drab color. When I initially received it I was surprised at the small size and dubious about its ability to shelter my 6'5" frame. Setting it up for the first time was easy - I used a tip that I found online and staked out the back corners first, put the pole into position with the pole guyline, then staked out the rest including the rest of the guylines. When I climbed inside I was very surprised at the head room I had, given the small footprint. For tall folks I recommend using all of the guylines since it helps create more head and foot room. For the first time ever I did NOT seam seal a new shelter. I figured I would test this one to see if the factory seam sealing was adequate, and it's proved to be waterproof so far (two nights backpacking with overnight rain, no leaks). If you like having a lot of gear inside your shelter this may not be the one for you. I had about 12" of space along one side to store a few items. But overall I am very glad I purchased this one!
