Zpacks Duplex Review

Zpacks Duplex Review

Looking for one of the lightest fully enclosed backpacking shelters on the market? In this Zpacks Duplex review, we break down why this ultralight Dyneema tent is so popular among thru-hikers, minimalist backpackers, and anyone looking to shed serious pack weight.

The Zpacks Duplex is an ultralight, two-person trekking-pole tent made from Dyneema Composite Fabric (DCF), a high-performance material known for being incredibly light, waterproof, and strong. Weighing in at just 18.5 oz (without stakes or poles), the Duplex is a standout for thru-hikers looking to keep their base weight as low as possible. Despite its minimal weight, it still offers ample space for one person plus gear or a snug fit for two.

The single-wall design and non-freestanding setup require some practice, and condensation can be a factor in humid conditions, but those are common trade-offs for ultralight tents. For experienced hikers who prioritize weight savings, the Duplex is a serious contender.

Comparisons

Zpacks Duplex vs Big Agnes Copper Spur HV UL2

The Zpacks Duplex is dramatically lighter and packs smaller, making it ideal for thru-hikers and ultralight purists. However, the Copper Spur HV UL2 offers easier setup, more durability, and better protection from condensation. Choose the Duplex for weight savings and the Copper Spur for all-around comfort.

Zpacks Duplex vs MSR Hubba Hubba 2

The MSR Hubba Hubba 2 is much heavier but offers better storm resistance, ease of setup, and long-term durability. The Duplex requires more care and is best suited for experienced backpackers who know how to pitch non-freestanding shelters in varied terrain.

Frequently Asked Questions

Is the Zpacks Duplex good for beginners?
Not really. It’s best suited for experienced hikers who are comfortable with non-freestanding shelters and pitching with trekking poles.

Does the Duplex require trekking poles?
Yes, it uses two trekking poles for setup. You can also buy separate carbon poles from Zpacks.

How does the Dyneema fabric hold up?
It’s waterproof and strong, but it can puncture more easily than heavier fabrics. It requires more care, especially on rocky terrain.

How does it handle condensation?
Like many single-wall tents, it’s prone to condensation in humid or wet conditions. Proper ventilation and site selection help reduce this.

Can two people use it comfortably?
Yes, but it’s a snug fit. It works best as a roomy solo shelter or a shared space for hikers who pack light and don’t mind close quarters.
