A perfect choice for those packed down campsites in the Sierra or camping along the beach, the Free Duo is a 1 or 2 person ultralight freestanding tent designed with versatility in mind.

Featuring a unique H-Pole frame design, the lightweight Free Duo excels in high wind situations.

This freestanding tent is ideal for hikers who regularly pitch on a variety of tough surfaces like bedrock, compacted dirt, sand, snow, or other places where using stakes may be difficult.

The Free Duo provides the versatility of a freestanding tent with all the benefits of an ultralight shelter made from Dyneema® Composite Fabric.  It is truly a go-to tent for just about any backpacking trip.

An optional flat groundsheet is available for added protection here.

Check out The Trek's review of the Free Duo review here.


  • The Free Duo is a dedicated freestanding tent which pitches with two included ‘H’ shaped tent poles. It can be pitched on difficult surfaces like bedrock, compacted dirt, sand, snow or other places that staking is inconvenient. This tent CAN NOT be set up with trekking poles.

  • The included ‘H’ shaped Easton Carbon 6.3 tent poles are made with proven technology and are the cutting edge of strength and weight. These poles are thicker and stronger than the Easton Carbon 3.9 poles used on our Duplex Flex shelter.

  • The Free Duo is our best tent in demanding, high wind situations. The Easton Carbon poles can handle a gale with minimal deflection. The tent body comes down nearly to the ground at the ends to help block cold wind. It pitches with a lower profile and a smaller footprint compared to our non-freestanding tents.

  • The tent can be picked up and moved around after inserting the poles to find the perfect root-free spot.

  • The tent can be pitched with zero stakes in calm, dry weather, however 2 stakes are required if you wish to deploy the storm doors. Up to 8 stakes should be used in windy weather.

  • Any of the four storm doors can be opened or closed independently. Leave all four open on nice weather nights for a breeze and great views. Close the upwind doors to block cold wind, or close all four 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 tarp overhangs the bathtub floor by 4-5 inches (12 cm). In calm rain or under wet trees one or two 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.

  • Rainbow zippers on both sides of the tent allow easy entry regardless of which doors are closed, and they give you access to every vestibule area.

  • This tent has a solid, sewn in 6 inch (15 cm) tall bathtub floor. The bathtub floor is a rectangle 42 inches wide by 7.5 feet long (107 cm x 2.29 m). The floor width will fit two adults side by side on standard width sleeping pads, or the tent is excellent for one hiker to spread out with gear. The freestanding poles lift up the head and foot ends of the tent for excellent space so that you don’t contact the walls.

  • Mesh pockets are conveniently located near each screen door so that they can be accessed from inside or outside the tent. They are a good place to store your cell phone, glasses, headlamp, the tent stuff sack, and spare seam tape (included). The pockets are 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.

  • There is screen between the bathtub floor and the walls at the ends of the tarp. The edges of the floor are 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.

  • The tent packs down small, around 6” x 12” (15 cm x 30 cm). It ships in a loose 7” x 13” (18 cm x 33 cm) stuff sack. The tent poles fold to 20” (51 cm) long and have their own stuff sack. They pack well standing vertically in your backpack’s side pocket, or inside your pack.

  • Dyneema Composite Fabric is naturally waterproof and is not treated with any potentially harmful chemicals such as flame retardants or water repellents. Our shelters are all PFC/PFAs free.
  • 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 .66 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 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.

.55 oz/sqyd Standard Dyneema® Composite Fabric

Available in Blue, Olive Drab, and White

The default canopy material choice on this tent is .55 oz/sqyd Dyneema® Composite Fabric. It has high tensile strength and can handle strong winds, storms, and all the typical conditions a tent will be in. All Dyneema® Composite Fabric material can easily be repaired in the field with the included repair tape if it were to get a puncture.

The material is semi-transparent, allowing you to see the silhouette of trees when looking out. In bright sunlight, you can see the fuzzy silhouette of a person when looking in, but it is opaque in low evening light.

Tensile Strength: 63 lb/in (552 N/5cm)

Puncture Strength: 
1.8 lb (8 N)

Water Resistance:
 15,000 mmH₂O

Made in the USA.

.75 oz/sqyd Dyneema® Composite Fabric

Available in Burnt Orange, Dirt, and Spruce Green

This canopy material has a higher Dyneema® thread count which gives it a higher tear strength. The standard material is already difficult to tear, so this weight is unnecessary. Many thru-hikers like this feature for added peace of mind.  It is also a bit thicker and darker than the standard weight. It is less transparent and offers more privacy.

Tensile Strength:
 104 lb/in (911 N/5cm)

Puncture Strength:
 3.1 lb (14 N)

Water Resistance:
 20,000 mmH₂O

Made in the USA.

1.0 oz/sqyd Dyneema® Composite Fabric

Our tent floor material is made with a membrane that is more than twice as thick as our canopy material. It is more puncture and abrasion resistant. This is the standard floor material on all of our tents.

Tensile Strength:
 104 lb/in (911 N/5cm)

Puncture Strength: 3.5 lb (15.5 N)

Water Resistance: 20,000 mmH₂O
Made in the USA. 

.67 oz/sqyd Ultralight Nano-Noseeum Insect Netting

Regular "No-see-um" bug netting weighs about 1 oz/sqyd. This ultralight version weighs roughly a third less without a noticeable difference in performance. It has extremely small holes which block even the smallest of insects including mosquitoes, noseeums, etc. Nothing gets through this screen.

Cutting Guylines:

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, there are six pieces of cord, each cut at 54 inches (137 cm). The front center stake loop is tied at 20" (51 cm) from the end of the cord.

Setup Instructions:

  1. Insert the the tips of the "H" shaped tent poles into the rings at the corners and peaks of the tent. The center part of the "H" should be horizontal. Make sure that the tips at the peaks of the tent are criss-crossed. Crossing the tips at the peak helps keep the tent splayed open.

    Clip the wall clips to the horizontal part of the "H" poles. They may be tight, especially on the first few pitches.

  2. If conditions warrant it, stake out the storm doors, the side walls, and the corners. In strong wind use all eight stakes for the best stability.

Storm Doors:

Any of the four 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. 

Seam Sealing:

All Zpacks shelters have taped seams and bonded tie outs! No seam sealing necessary.
