This Zpacks Free Duo Tent review examines a two-person, two-door, two-vestibule, freestanding, hub-and-pole, single-wall shelter with a tent body constructed of Dyneema Composite Fabric. The Zpacks Free Duo Tent retails for $849 and weighs 30.1 ounces (852 g) including carbon poles.

Zpacks designed The Free Duo Tent for backpackers who camp regularly on surfaces such as sand or rock where stakes are sometimes useless. It may draw the attention of nonfreestanding tent users weary of pounding stakes into rocky, sandy, or frozen soil or current freestanding tent users looking to drop a pound from their current setup.

Review context

The Zpacks Free Duo is one of a handful of two-door, two-vestibule, hub-and-pole, two-person freestanding tents weighing around two pounds (.9 kg). A few shelters in this category are made from Dyneema Composite Fabric (DCF), such as the Big Agnes Tiger Wall 2 Carbon. A few are made from 7D silnylons, such as the Big Agnes Tiger Wall 2 Platinum.

The Free Duo differs from most tents in this category because it is single-walled instead of double-walled and constructed from more durable fabrics.

Increasing the weight range by about a pound reveals more shelters that could match the Free Duo’s durability at the expense of weight.

These shelters generally cost about half the price of the Zpacks Free Duo. The Big Agnes Copper Spur HV UL2 and the MSR Hubba Hubba 2 are examples of tents in this sub-category. It is hard to say if the Free Duo competes directly with either of these tents. However, it makes sense to imagine a user turned off by the Free Duo’s downsides but who still appreciates the features of tents in this category. In this case, the next logical step is to start looking at something like the Hubba Hubba 2, even though it weighs a pound more.

This article is a Performance Review based on using the Zpacks Free Duo Tent in a variety of environments on several multi-day backpacking trips. Read more about our types of reviews here.

Category overview

In this Zpacks Free Duo review, I will identify the best use-cases for the shelter. I will judge its performance within the category of two-person, two-door, two-vestibule, hub-and-pole shelters instead of comparing it to trekking-pole supported shelters. Rather than spending too much time in the body of the review discussing the relative pros and cons of the category, I would like to take a moment and do that here.

List of performance criteria

I reviewed the Zpacks Free Duo based on the following criteria:

  • freestanding design / pitching
  • fabric
  • durability
  • weight
  • livability
  • storm worthiness
  • finish quality / aesthetics
  • price

Freestanding design / pitching

The Zpacks Free Duo Tent uses a hub-and-pole system of two H-shaped carbon fiber poles, one for each end of the tent. The poles meet each other on each side of the shelter at the center axis but do not connect.

The two h-poles don’t connect, but rather overlap at the peak, secured by tiny metal rings.

The pole ferrules insert into tiny metal grommets sewn to the corners and peak of the tent. The fabric end panels then snap to the horizontal part of the pole-set with plastic tent-pole clips. I found it easiest to connect these clips to the poles by snapping them to the center of the pole and then sliding the clips horizontally towards the pole hubs. The flexibility of the pole makes this possible. With all the poles in place, the canopy fabric is tight.
