Understanding PFAS Chemicals in Tents

← Gear Maintenance & Repair | Tent Care & Repair

Quick answer

• PFAS are a group of chemicals used for waterproofing and stain resistance in tents.
• They are persistent, meaning they don’t break down easily in the environment.
• Look for tents labeled “PFC-free” or “PFAS-free” if you want to avoid them.
• Consider tents made from natural fibers or those with alternative water-repellent treatments.
• PFAS can be a concern for environmental persistence and potential health impacts.
• Research brands that are transparent about their material sourcing and chemical use.

What to check first (do this before you drive out)

Before you even think about packing the car, a little homework goes a long way. Especially when it comes to your shelter.

• Land manager / legality: Who’s in charge here? Is it National Forest, BLM land, a State Park? Each has its own set of rules. You don’t want to roll up to a closed road or a campsite you can’t legally use. Always check the official website for the specific area you’re headed to. It’s usually pretty straightforward, but a quick look saves headaches.

• Access/road conditions: Is that “road” to your dream spot really a road, or just a suggestion? Some trails are fine for your trusty sedan, others demand 4WD and high clearance. Mud, snow, or just plain washboard can turn a fun trip into a tow-truck situation. Check recent trip reports or call the ranger station if you’re unsure. I learned that one the hard way after getting stuck in a spring mud pit.

• Fire restrictions + weather + wind: This is non-negotiable. Fire bans are serious business, and getting busted for a rogue campfire is a quick way to ruin a trip. Check the current fire restrictions for the area. Then, look at the weather forecast. High winds can make setting up a tent a wrestling match and can also be a fire hazard. And don’t forget to check for severe weather alerts.

• Water plan + waste plan (Leave No Trace): Where are you getting your water? Is there a reliable source, or are you packing it all in? If you’re using natural sources, you’ll need a filter or purification method. And what about trash? Pack it in, pack it out. That’s the golden rule. Plan for all your waste, including food scraps and hygiene products.

• Safety (wildlife, distance to help, comms): What kind of critters are in the area? Bears, snakes, mountain lions? Know what to do and how to store your food properly. Also, how far are you from the nearest town or help? Cell service is often spotty at best. Tell someone where you’re going and when you expect to be back. A satellite messenger can be a good investment for remote trips.

Step-by-step (field workflow)

Alright, you’ve done your homework. Now it’s time to set up camp. This is where the rubber meets the road, or in this case, the tent poles meet the ground.

1. Scout your tent site:

• What to do: Look for a flat, clear spot, ideally with some natural shelter from wind. Avoid setting up in dry creek beds or directly under dead trees.
• What “good” looks like: A level spot free of rocks, roots, and debris. You can lie down comfortably without feeling a pointy bit poking you.
• Common mistake: Pitching your tent in a low-lying area that could fill with water if it rains. Avoid it by looking for slightly elevated ground.

2. Clear the ground:

• What to do: Remove any rocks, sticks, or pinecones from the area where your tent footprint will be.
• What “good” looks like: A smooth surface that won’t puncture your tent floor or make sleeping uncomfortable.
• Common mistake: Leaving sharp rocks or branches under the tent. This can lead to tears in the fabric, and trust me, that’s a bad time.

3. Lay out the footprint (if you have one):

• What to do: Place the footprint on the cleared ground, ensuring it’s oriented correctly for your tent.
• What “good” looks like: The footprint is centered and its edges are mostly within where the tent will be pitched, protecting the tent floor.
• Common mistake: Forgetting the footprint or laying it out so it sticks out beyond the tent. This can catch rain and channel water under your tent.

4. Unpack and orient the tent body:

• What to do: Unpack the tent body and lay it out on the footprint. Orient the doors where you want them, considering the view or prevailing wind.
• What “good” looks like: The tent is spread out flat, with the doors facing the desired direction.
• Common mistake: Not checking the door orientation before you start inserting poles. You might end up with your main entrance facing a bush.

5. Assemble and insert tent poles:

• What to do: Connect the pole sections and carefully insert them into the designated sleeves or clips on the tent body.
• What “good” looks like: Poles are fully connected and slide smoothly into place, creating the tent’s structure.
• Common mistake: Forcing poles or bending them incorrectly. Be gentle; they’re designed to flex, but not to be manhandled.

6. Raise the tent:

• What to do: Lift the tent structure into place by bending the poles and securing them to the tent corners or grommets.
• What “good” looks like: The tent is standing up, taut and stable, with the poles securely anchored.
• Common mistake: Not fully seating the poles in the grommets or clips. This can cause the tent to collapse under stress.

7. Stake out the tent body:

• What to do: Secure the tent corners to the ground using stakes. Angle the stakes at about 45 degrees away from the tent.
• What “good” looks like: The tent is taut, with no saggy fabric, and the stakes are firmly in the ground.
• Common mistake: Driving stakes straight down or not using enough of them. This makes your tent vulnerable to wind.

8. Attach and tension the rainfly:

• What to do: Drape the rainfly over the tent body and secure it to the poles and tent corners. Adjust the tension straps so the fly is taut and not touching the inner tent.
• What “good” looks like: The rainfly is evenly distributed, creating a waterproof barrier with good airflow between it and the inner tent.
• Common mistake: Not tensioning the rainfly properly. This can lead to condensation buildup inside the tent or the fly pooling water.

9. Stake out guylines:

• What to do: Extend and stake out the guylines for added stability, especially in windy conditions.
• What “good” looks like: Guylines are taut and anchored securely, providing extra support to the tent and rainfly.
• Common mistake: Skipping guylines. They are crucial for wind resistance and keeping the rainfly from flapping.

10. Organize your gear inside:

• What to do: Bring your sleeping bag, pad, and other essentials inside. Use internal pockets for smaller items.
• What “good” looks like: Your gear is neatly stored, leaving ample space for you to move around.
• Common mistake: Piling everything in a heap. It makes finding things difficult and reduces usable living space.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Ignoring fire restrictions	Fines, damage to the environment, and a wildfire.	Always check current restrictions before you go. If in doubt, have a stove or cold meal.
Pitching in a dry creek bed	Flash floods can happen even if it hasn’t rained where you are.	Scout for slightly elevated ground away from obvious water channels.
Not checking road conditions	Getting stuck, vehicle damage, or needing a tow.	Call the ranger station or check online for recent conditions. Know your vehicle’s limits.
Forgetting a water filter/purifier	Dehydration or getting sick from untreated water.	Pack a reliable filter, purification tablets, or boil water. Always have a backup plan.
Leaving food accessible to wildlife	Bears or other animals raiding your camp, potentially becoming habituated.	Use bear canisters, hang food properly, or store it in your vehicle away from sleeping areas.
Not staking out guylines	Tent collapsing in wind, rainfly flapping, or poles bending.	Always use guylines, especially if wind or rain is in the forecast.
Not tensioning the rainfly correctly	Condensation inside the tent, water pooling on the fly, or reduced ventilation.	Adjust all tension points until the fly is taut and there’s a gap between the fly and the inner tent.
Leaving trash behind	Polluting the environment, attracting wildlife, and ruining the experience.	Pack out everything you pack in, including food scraps and toilet paper. Leave No Trace.
Setting up under dead trees/branches	Falling limbs can damage your tent or cause injury.	Look up! Scan for any “widowmakers” before you commit to a spot.
Not bringing a first-aid kit	Minor injuries becoming major problems, or being unprepared for emergencies.	Pack a comprehensive kit and know how to use its contents.
Assuming cell service will be available	Inability to call for help or communicate your location.	Download offline maps, carry a satellite messenger, and always tell someone your itinerary.

Decision rules (simple if/then)

• If the forecast calls for heavy rain, then pitch your tent on slightly higher ground because water naturally flows downhill.
• If you’re in bear country, then store all food and scented items in a bear-resistant container or hang them properly because you don’t want a midnight visitor.
• If the wind is picking up, then deploy all guylines and ensure they are taut because a well-guyed tent can withstand much stronger gusts.
• If you see signs of animal activity (scat, tracks), then be extra vigilant about food storage and campsite cleanliness because you’re sharing the space.
• If you’re unsure about water source safety, then always filter or purify it because giardia is no fun.
• If the road to your campsite is rough, then proceed slowly and check for obstacles because damaging your vehicle miles from help is a bad situation.
• If you’re camping solo, then tell someone your exact location and expected return time because it’s critical for your safety.
• If there are fire restrictions in place, then do not have an open fire and use a camp stove because violating these rules has serious consequences.
• If you notice any damage to your tent before pitching, then assess if it’s repairable or if you need to find an alternative shelter because a compromised tent is a risk.
• If you’re setting up in a popular area, then consider arriving earlier in the day to secure a good spot because the best spots go first.
• If you’re experiencing condensation inside your tent, then check that the rainfly is properly tensioned and that vents are open because airflow is key to managing moisture.

FAQ

What are PFAS chemicals in tents?

PFAS are a group of man-made chemicals that manufacturers often use to make tent fabrics water-repellent and stain-resistant. They are sometimes called “forever chemicals” because they don’t break down easily.

Are all tents treated with PFAS?

No, not all tents contain PFAS. Many brands are moving away from these chemicals and offering “PFC-free” or “PFAS-free” options. It’s worth checking product descriptions.

Why should I care about PFAS in my tent?

PFAS can persist in the environment for a very long time. While direct health impacts from tent exposure are less understood, there’s growing concern about their environmental presence and potential long-term effects.

How can I find a tent without PFAS?

Look for labels or product descriptions that explicitly state “PFC-free,” “PFAS-free,” or “DWR-free” (Durable Water Repellent, if the DWR is not PFAS-based). Some brands are more transparent than others about their materials.

What are the alternatives to PFAS for waterproofing?

Some tents use alternative DWR treatments that are not PFAS-based. Others rely on the inherent water-resistance of tightly woven fabrics or use natural materials like canvas, though these often require re-waterproofing over time.

Can I remove PFAS from my tent?

Once applied, PFAS treatments are generally integrated into the fabric and cannot be easily removed. The best approach is to choose a tent made without them from the start.

Do PFAS treatments affect the performance of my tent?

Historically, PFAS-based treatments were very effective at providing durable water and stain resistance. Newer, PFAS-free alternatives are improving, but performance can vary by brand and specific treatment.

Where can I learn more about PFAS in outdoor gear?

Many outdoor gear review sites and environmental advocacy groups publish information on PFAS and their use in products. Researching specific brands and their sustainability reports is also helpful.
