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. Click here for tips to avoid condensation.
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.

- 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.
.66 oz/sqyd Dyneema® Composite Fabric
This canopy material choice has the same Dyneema® thread count as standard .55 oz/sqyd, but with a slightly thicker laminate that allows for a darker color or pattern to be printed on the material. The thicker laminate brings the fabric weight to .66 oz/sqyd. It blends in to nature well. It is darker, less transparent and offers more privacy. Dyneema® Composite Fabric has a bit of a sheen to it when it is new, but it dulls down significantly with some use.
This video by John Abela shows the opacity and color of the camo fabric. It adds around 1.0 ounces (30 grams) to the weight of the Duplex.
Tensile Strength: 63 lb/in (552 N/5cm)

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.

Shipped all the way to the UK very quickly. Used for over a week in strong wind and rain, it's bomb proof!
Easy setup and packup. Good durability predicted; Highly functional and practical for most 3 season use- to simulate a freestanding tent, I will be using snow/sand anchors attached to its guylines. Need to be more selective about staying out of high winds compared with my 4 season Hillebergs (Soulo and Allak) but so much lighter!!!!!!! Highly recommended.
High quality and elegant design.
so far so good lighter than a fart in a fan and half the size;)) ty bunches love it
Used for a quick overnighter on the pinhoti. Very good shelter overall. All the seams i saw looked good. Weight was spot on as advertised. Easiest pitch of all my shelters. Cant wait to get it on the AT.
