When I started back into backpacking and assembling lighter gear, I never thought about tent fabrics, and I found what was the best option at the price I was willing to pay. I started reading about this tent called the Duplex from Zpacks and dug into dyneema. I wanted to know why people were infatuated with it in the thru-hiking world.

DCF tents are built using material that requires specialty machinery to assemble, making it expensive and not widely used by bigger outdoor companies. This is what makes it more common with cottage gear companies. Dyneema tents costs 2-3 times a similar sil-nylon tent, but a DCF shelter is half the weight or sometimes less; the savings in weight is what pulls in thru-hikers.

For me, it is a perfect option for trail life since it is fast to set up and ultralight to carry for 1000s of miles. Let's dig into the benefits and drawbacks to DCF, as it may be a good decision for you to make when gearing up for a thru-hike.

Understanding the Unique Properties of Dyneema Composite Fabric

Dyneema fiber was built originally for sailboat sails, as it is incredibly strong for its weight and, along with its waterproofness, makes it ideal for constructing a durable and lightweight tent.

Though with all these benefits, there are still problems which cause it to be less used as a material for many manufacturers. It is costly to purchase, machine, and nearly impossible to dye, so you also have very limited color choices.

The High Costs and Challenges of Producing DCF Gear

Much of this has to do with exceptional costs, being both labor-intensive and difficult to acquire and to create, let alone sell. DCF requires very specific needs in equipment to sew it, and this gear isn't the same as traditional equipment.

This keeps the number of companies that can produce DCF products limited to those with a lot of financial backing and those willing to create and possibly suffer losses from failed sales runs.

This has been slowly changing as more and more companies can acquire the right equipment, but it is still a significant investment.

The end product is also much more expensive than what you find, limiting the audience who can and will buy, leading many bigger brands to avoid it entirely.

The Limited Color Palette of DCF Shelters

Most colors are limited to very light colors; the most common are translucent white, blue, and light green.

There is also black, but this makes for a poor shelter color as it warms the interior from the sun's heat, making it unbearable in hot weather.

Field Testing DCF: Strengths and Weaknesses Revealed

Dyneema is a tough fabric, but it is not indestructible. The material's weave can catch on and tear; however, it will not run like traditional nylon fabrics.

You need to be most careful with the seams as they are sewn and not glued, making for a less resistant connection point.

Take care when setting up and taking down your shelter not to catch anything on the corners.

I could not pull apart the bonded seam but I could pull apart every stitched seam that I made. The bonded seam performed as if there were no seam at all, and it was just like trying to pull apart a continuous piece of 2″ wide DCF which I cannot do. - Backpacking Light

One of the great things about DCF is that it can be repaired in the field with needle and thread quite easily as long as you have a little patience.

I have had to do this a few times already, and it has been relatively painless.

Weighing the Pros and Cons of DCF Tents

There are definite pros and cons between a DCF tent and other more traditional materials like sil-nylon.

First, let's look at the Pros:

DCF’s Winning Features: Lightweight, Waterproof, and Durable

There are loads of beneficial parts to DCF as a shelter material that can make the exorbitant cost well worth the investment.

The biggest are weight reduction, waterproof, not stretchable, and strong tear resistance; let's dig in.

Large Weight Reduction

The primary advantage of DCF is how incredibly lightweight it is for what it can do. You will often see a sil-nylon tent that weighs around 3 lbs and then a comparable DCF one at 1.

This is due to most single-wall tents are the gold standard for lightweight shelters on the trail.

Throughout 2000+ miles, this is significant to your bodily health, including your knees and feet. This weight savings also allows you to use a lighter and smaller backpack as you aren't hauling as much weight around.

Waterproof

One of the main reasons that DCF was created in the first place was for sails on boats; it needs to be incredibly waterproof while being lightweight, which made it perfect for extending use into hiking.

This excellent waterproofing extends to DCF tents and excels in heavy rain. At the same time, you may think that since the fabric is waterproof, this alone would keep you bone-dry, but since you need to attach doors and parts to the tent, you create micro holes to attach with a sewing machine.

This means tents have extra work added to either tape these seams in creation, hot bond the DCR layers together, or seam seal with a sealant to help protect you fully in the heaviest of downpours.

Not Stretchable

As DCF is not stretchy, it will hold its shape in all conditions, so you won't have to worry about your tarp or bathtub floor sagging in the rain as waterlogged sil-nylon can.

This also keeps the tent more stable in high winds as it can't flap as much due to the lack of giving.

Massive Tear Resistance

One of the lesser-known advantages of DCF is its incredible tear resistance for how light it is. This is due to the extremely tough fibers used in its construction and is a result of it being designed for sails.

You will often see people use this as their only shelter material on long-distance hikes as it can take a beating day in and day out and still perform admirably.

Potential Downsides: Cost, Transparency, and Noise Issues

There are some drawbacks to DCF as your go-to material, but most are avoidable with a little extra care.

The main issues are its sheer cost, the fact the material is very translucent, providing limited privacy, and that the DCF can make loads of noise when it's windy.

Extremely Expensive & Cost Prohibitive

Any tent body built with Dyneema will not be light on the wallet. For most DCF shelters, you will have to look at paying a minimum of around $600 for the shelter alone without tent stakes.

This is a lot of money for most people and often puts the DCF option out of reach. If you have the budget, it's well worth the investment as you will save so much on weight while not losing any strength or durability.

Near Translucent & Limited Privacy

As I mentioned above, since DCF is so light, it is also very translucent. This doesn't mean you can see through it like a window, but in the right lighting or with a headlamp inside, you can easily make out the shape of a person.

🚨
This translucency provides little in the way of privacy and can be a deal-breaker for some people. Many will be concerned when hiking with or around others, especially strangers.

For many, this limits its use as they don't want to be on display, and it is often one of the main reasons people shy away from DCF shelters outside of the cost itself.

Noisy Enough To Interrupt Sleep

Another drawback that can often discourage people is how incredibly loud DCF can be in high winds. When the wind is whipping around your shelter, it can make a loud crinkling sound that can be enough to disrupt sleep.

To help combat this, some companies have started using a thicker DCF that helps to deaden the noise somewhat, but it's still an issue for those particularly sensitive to noise when trying to sleep.

Most Require Trekking Poles

Many DCF shelters are trekking pole tents which means you will need to use trekking poles as the primary support structure. Due to this, if you choose to day hike you wouldn't have them available without taking down your shelter.

⚖️
The need for poles is due in large part to the choice people make wanting to be ultralight and not single-use gear that isn't easily fixed on trail.

While this isn't an issue for some, others may not carry poles or want to use their trekking poles for a chair or other needs, limiting the usefulness of DCF shelters in those situations.

Assessing the Longevity of Your DCF Tent Investment

The lifespan of any tent depends on how you care for it and how often you use and abuse it, and a thru-hike is pretty brutal on gear due to the length of time you use it.

For most, a DCF tent will last them many years if they take care of it, with some companies even offering a lifetime warranty on the material itself.

In terms of a thru-hike, the normal life expectancy would be a single thru-hike. Many people, though, have had their same tent through multiple thru-hikes. Much of this longer life comes from the way you treat the material while travelling.

So the real story is your mileage may vary. You might get years out of a Dyneema tent or just one thru-hike, but what matters is you take care of your gear and know its limitations.

Making the Case for Investing in a DCF Tent

When you are on a thru-hike, you are on the trail, and your shelter is your "home," Most homes will cost you much more than $600-700 dollars and be nowhere near as transportable.

To me, this makes a DCF tent as a shelter for 5+ months worthy of the investment for a thru-hike attempt.

Having a safe place to sleep that is comfortable, dry, and bug-free makes all the difference in the world when you are out there for months.

Due to its durability, the DCF option will cost you less in the long run. So while the upfront cost may be high, the long-term savings make this a great investment for those who can afford it and treat their tent with care.

Ultimately, what matters is what works best for you and what you are willing to spend to make your hike more comfortable.
