Lightweight Tents For Backpacking

Looking for a lightweight tent that won’t weigh you down on your next backpacking trip? Look no further than the Zpacks Duplex and Altaplex.

These two tents are known for their exceptional weight-to-feature ratio, making them a top pick among ultralight hikers.

The Zpacks Duplex weighs in at just over one pound, thanks to its use of Dyneema fabric and trekking pole structure. Despite its featherlight construction, this tent doesn’t skimp on features.

It boasts ample interior space for two people, as well as vestibules on either side for storing gear. Plus, having the interior mesh zippered walls provides excellent ventilation while also keeping bugs out.

If you’re looking for a top-notch ultralight shelter, consider the Altaplex. This pyramid-style tent has a smaller space footprint that can be attractive to those minimizing pack size.

And due to this smaller size, it has an impressive weight of only 18 ounces. The single-pole design makes setup a breeze, and the steep walls help to prevent serious condensation buildup inside the tent.

As you can see, both the Zpacks Duplex and Altaplex offer unbeatable value when it comes to tent weight and features. But how do they stack up when it comes to size and capacity? Let’s take a closer look.

Size And Capacity Comparison

When it comes to size and capacity, both the Zpacks Duplex and Altaplex offer ample interior space for backpackers. The Duplex has a floor area of 28 square feet, while the Altaplex provides slightly less with 22.5 square feet.

Overall, choosing between these two tents will depend largely on your personal preferences regarding space and weight.

Most would choose the Altaplex if tall or looking to be as low a weight as possible but if you prefer a lightweight but need extra floor space for multiple hikers or gear storage, then go with the Duplex.

In either case, both shelters are excellent options for ultralight backpacking adventures.

As we move on to discussing differences in design and setup between these two tents, keep in mind how each model’s size and weight distribution might affect your decision-making process when selecting which one to purchase.

Design And Setup Differences

Moving on from the size and capacity comparison, let’s take a look at the design and setup differences between the Zpacks Duplex and Altaplex.

Both tents are made by the same very reputable outdoor gear company in Zpacks, but they each have unique features that make them stand out from one another.

Firstly, when it comes to ease of use, both tents are relatively easy to set up. However, the Altaplex has a slight advantage in this department due to its single-pole construction which makes it simpler to pitch than a Duplex imho.

The only caveat here is that the Altaplex and the Duplex have lots of guy lines which also contributes to their set-up times.

In terms of maintenance requirements, both tents share minimal upkeep. They are both made with Dyneema Composite Fabric (DCF), which requires careful handling during use and cleaning as abrasion can weaken the material over time.

Moving forward into materials and durability comparisons between these two tents, we’ll see how well they hold up against harsh weather conditions and wear and tear in extended camping trips.

Materials And Durability

When it comes to choosing between the Zpacks Duplex and Altaplex, one of the most significant factors to consider is their durability.

Both shelters use high-quality materials that are designed to withstand harsh outdoor conditions, but which one offers a better long-term investment?

Durability comparison:

  • Each tents feature either a 0.55 or a 0.75 oz/sqyd Dyneema Composite Fabric (DCF) canopy based on color choice and a bathtub floor made from 1.0 oz/sqyd DCF with reinforced corners.

Material quality assessment:

Both shelters use top-of-the-line materials in construction, making them among the best ultralight backpacking tents available on the market today.

When considering these two shelters’ durability and overall material quality, there isn’t an obvious winner. While both have exceptional performance credentials, your choice may depend on other factors such as weight, pole need, price, or other more personal preferences.

Moving forward into weather resistance and performance, let’s examine how each shelter handles tough weather conditions like wind, rain, and snow.

Weather Resistance And Performance

Now that we’ve covered the materials and durability of both the Zpacks Duplex and Altaplex, let’s move on to their weather resistance and performance. These are key factors when it comes to choosing a tent for outdoor adventures.

One aspect where these two tents differ is their design. The Duplex uses two trekking poles as its main support while the Altaplex uses just one trekking pole.

This means you’ll need to bring your full set of trekking poles if you choose the Duplex, which could be an inconvenience for some hikers.

When it comes to body/rainfly coverage, both tents offer the best protection against rainfall due to the use of Dyneema as this material is waterproof with the exception of how seams are sewn.

The Altaplex has a smaller footprint compared to the Duplex, which affects its overall protection and coverage area.

While not necessarily a dealbreaker, it’s something to keep in mind especially if you’re planning on long-distance hiking where you may want more inside space to air out gear and maybe wait out a storm when in areas with unpredictable weather conditions.

Transitioning into ventilation and breathability: Despite their differences, both tents provide decent ventilation thanks to their ability to open the doors and pitch high allowing airflow in from below.

Ventilation And Breathability

One of the most important factors to consider when choosing between the Zpacks Duplex and Altaplex is their ventilation and breathability performance.

Both tents have slightly different designs that affect airflow, which can affect moisture management inside the tent.

The Zpacks Duplex design allows for plenty of airflow through its dual doors as you can open one or both on either side to allow air movement.

This helps prevent massive condensation buildup inside the tent, making it an ideal choice for humid environments.

Additionally, its two opposite sets of two doors make it easy to ventilate from either or both ends of the tent, allowing for optimal circulation.

On the other hand, the Altaplex offers less ventilation due to its single opening side. However, its doors being opened can help circulate air efficiently while still keeping out rain. Its steep pitch also aids in preventing moisture buildup on its interior walls.

Choosing between these two tents ultimately comes down to personal preference and intended use. If you’re looking for maximum condensation support and superior ventilation, then go for the Zpacks Duplex.

But if weight is your primary concern and you’ll be camping in areas where humidity isn’t as much of an issue, then you may find that the streamlined design of the Altaplex fits your needs better.

Price And Value For Money

When it comes to backpacking gear, the price point can often make or break a purchase decision. Both the Zpacks Duplex and Altaplex are high-quality ultralight tents that come with a hefty price tag.

However, when considering their long-term investment value for money, there are some pros and cons to consider.

The Zpacks Duplex is more expensive than the Altaplex but offers more space for two people and has two doors and vestibules. It also sets up quickly and easily with trekking poles.

On the other hand, the Altaplex is lighter in weight and more compact when packed down, making it easier to carry on long trips. Its single pole structure also makes set-up faster.

Overall, while the price point may initially seem steep for both options, they offer great value for money as high-quality ultralight tents that can withstand years of use .

Considering personal needs and weighing out pros and cons can help determine which tent will be worth investing in for each individual user.

User Reviews And Recommendations

Now that we have discussed the price and value for money in the previous section, let’s move on to user reviews and recommendations.

When it comes to choosing between the Zpacks Duplex and Altaplex, hearing from those who have personally used these tents can be incredibly helpful.

Based on personal experience and extensive research, here are some pros and cons of each tent:

Zpacks Duplex:

  • Lightweight and packable
  • Spacious interior with two doors
  • Durable construction
  • Condensation buildup can be an issue

Zpacks Altaplex:

Of course, everyone has their own preferences when it comes to gear. However, taking into account the experiences of others can help make a decision easier. Overall, both the Zpacks Duplex and Altaplex offer great options for backpackers looking for lightweight and reliable shelter on the trail.


After comparing the Zpacks Duplex and Altaplex, it’s clear that both tents have their strengths and weaknesses. The Duplex offers more space for two people and a slightly easier setup, while the Altaplex is lighter in weight and has better packability.

When it comes down to personal preference, your backpacking needs will dictate which tent is right for you. If you prioritize comfort over weight savings, the Duplex might be the way to go with their new Duplex Zip which is a version with a Zipper and Peak Vents.

However, if you’re looking for an ultralight option with top-notch weather protection, then the Altaplex could be worth the investment.

Overall, both tents are great options for lightweight backpackers who want high-quality gear that performs well in various conditions. It ultimately comes down to what features matter most to you and how much you’re willing to spend on your shelter. Regardless of which tent you choose, happy trails!
