What Are PFAS Chemicals in Tents?

← Camping Essentials & Setup | Shelter & Sleeping Gear

Quick answer

• PFAS are a group of man-made chemicals found in some outdoor gear, including tents.
• They’re used for water and stain resistance.
• Look for tents advertised as “PFC-free” or “PFAS-free” to avoid them.
• While effective, there are growing concerns about PFAS’s environmental and health impacts.
• Research and choose brands committed to safer alternatives.
• Understanding these chemicals helps you make informed gear choices for your next adventure.

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

Before you even think about packing, a few key checks will save you hassle and ensure a good trip.

• Land manager / legality: Who’s in charge of where you’re going? Is it National Forest, BLM land, a State Park, or private property? Each has different rules. A quick check on their official website or a call can clear up any confusion about permits, camping limits, or specific regulations. Don’t assume you know the rules; they can change.

• Access/road conditions: Is that dirt road a gentle path or a muddy mess? Check recent reports online or ask locals if you’re unsure. A standard sedan might be fine for some spots, while others demand 4WD and decent ground clearance. Getting stuck miles from nowhere is a bad start to any trip. I learned that the hard way once with my old Subaru.

• Fire restrictions + weather + wind: This is non-negotiable. Fire bans are serious business. Check the land manager’s site for current restrictions. Then, look at the weather forecast. High winds can make camping miserable and dangerous, especially in exposed areas. Rain? Wind? Be prepared.

• Water plan + waste plan (Leave No Trace): Where will you get water? Is it potable or does it need filtering/treating? And what about trash? Pack it in, pack it out. This is fundamental. Plan for gray water disposal too, away from water sources.

• Safety (wildlife, distance to help, comms): Know what critters are in the area and how to store food properly. How far is the nearest town or ranger station? Do you have cell service? Consider a satellite communicator for remote trips. Better safe than sorry.

Step-by-step (field workflow)

This is how you set up camp smoothly, like you’ve done it a thousand times.

1. Arrive and Scout: Pull over at your designated spot or a promising area.

• Good looks like: You’ve found a level, clear spot, ideally with some natural windbreak, and it’s away from hazards like dead trees.
• Common mistake: Rushing and picking the first flat spot you see, only to realize later it’s in a mosquito haven or prone to flooding. Take a minute.

2. Clear the Ground: Remove any sharp rocks, sticks, or debris from the tent footprint.

• Good looks like: A clean, smooth surface ready for your tent.
• Common mistake: Leaving small rocks or roots, which can puncture your tent floor or make sleeping uncomfortable. A quick sweep makes a big difference.

3. Lay Out the Footprint/Ground Tarp: Place it where the tent will go, ensuring it doesn’t extend beyond the tent’s edges.

• Good looks like: The footprint is perfectly positioned, ready to protect your tent floor.
• Common mistake: Letting the footprint stick out from under the tent. This catches rain and directs it under your tent, defeating its purpose.

4. Unpack and Orient Tent: Lay out the tent body and identify the doors and poles.

• Good looks like: The tent is spread out logically, poles are easily accessible, and you know which way is up.
• Common mistake: Trying to force poles into sleeves without checking orientation, leading to frustration and potential damage.

5. Assemble Poles and Insert: Connect the pole sections and feed them through the tent sleeves or attach them to clips.

• Good looks like: Poles slide smoothly and are securely in place, forming the tent’s structure.
• Common mistake: Bending or forcing poles. If it’s not going in easily, something’s wrong. Recheck the sleeve and pole path.

6. Raise the Tent Body: Lift the tent structure and connect the poles to the grommets or clips at the tent corners.

• Good looks like: The tent stands up on its own, looking taut and stable.
• Common mistake: Not fully seating the poles in the grommets, which can cause the tent to sag or collapse in wind.

7. Stake Out the Tent Body: Secure the corners of the tent to the ground with stakes.

• Good looks like: The tent is firmly anchored, with taut fabric walls.
• Common mistake: Skimping on stakes or not driving them in deep enough. This is crucial for wind resistance.

8. Attach and Stake the Rainfly: Drape the rainfly over the tent and secure it, ensuring it’s taut and doesn’t touch the inner tent.

• Good looks like: The rainfly is evenly distributed, creating a protective barrier and good ventilation.
• Common mistake: Not adjusting the rainfly properly. If it’s flapping or touching the inner tent, condensation or leaks can occur.

9. Stake Guylines: Use the guylines to further secure the tent and rainfly, especially in windy conditions.

• Good looks like: Guylines are tensioned correctly, adding significant stability.
• Common mistake: Forgetting guylines or not tensioning them. They’re your best friend in bad weather.

10. Ventilate: Open any vents on the rainfly and tent body to allow airflow.

• Good looks like: You can feel a gentle breeze moving through the tent.
• Common mistake: Keeping everything zipped up tight. This traps moisture and leads to condensation.

11. Organize Inside: Set up sleeping pads, bags, and gear, keeping the floor clear.

• Good looks like: A tidy, functional living space within your tent.
• Common mistake: Throwing gear everywhere. A little organization goes a long way for comfort and easy access.

12. Final Check: Walk around the tent, checking stakes, tension, and zippers.

• Good looks like: Everything is secure, taut, and ready for whatever the weather throws at you.
• Common mistake: Skipping this final sweep. A loose stake or snagged zipper can be a nuisance later.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Ignoring fire restrictions	Fines, devastating wildfires, jail time.	Always check official sources; if in doubt, no fire.
Driving on unmaintained roads unprepared	Getting stuck, vehicle damage, needing a costly tow.	Research road conditions; know your vehicle’s limits; have recovery gear if needed.
Not checking weather forecasts	Being caught in severe storms, hypothermia, damaged gear, miserable trip.	Check multiple sources; pack appropriate clothing and shelter.
Improper waste disposal	Attracting wildlife, polluting water sources, leaving a mess for others.	Pack out <em>all</em> trash, including food scraps. Use designated latrines or dig catholes properly.
Leaving food unsecured	Attracting bears, raccoons, or other animals to your campsite.	Use bear canisters or hang food properly; never store food in your tent.
Not staking guylines	Tent collapsing or blowing away in high winds.	Always deploy and tension guylines, especially in exposed areas or predicted wind.
Setting up camp too close to water	Contaminating water sources, damaging riparian areas, potential flooding.	Camp at least 200 feet from lakes, rivers, and streams.
Over-tightening tent poles/stakes	Damaging poles, ripping fabric, making tent difficult to set up/take down.	Apply firm but not excessive pressure; if it feels wrong, stop and reassess.
Not ventilating the tent	Excessive condensation, damp sleeping bags, uncomfortable sleeping.	Open vents and slightly crack zippers to ensure airflow.
Ignoring wildlife warnings	Dangerous animal encounters, injury to yourself or the animal.	Research local wildlife; maintain safe distances; know what to do if you encounter an animal.
Using a tent with a faulty zipper	Difficulty accessing tent, insect entry, potential gear damage.	Inspect zippers before your trip; carry a zipper repair kit or spare zipper pulls.
Not using a footprint	Punctured tent floor, premature wear and tear on the tent.	Always use a footprint or ground tarp sized correctly for your tent.

Decision rules (simple if/then)

Here’s how to make the call when things aren’t crystal clear.

• If the road is unmarked and overgrown, then turn back, because it might not be maintained or legal access.
• If the forecast calls for high winds and rain, then set up your tent in a more sheltered spot, because it will be more comfortable and safer.
• If you see animal tracks near your intended campsite, then reassess your location, because you don’t want to camp right on a game trail.
• If you can’t confirm fire regulations, then assume fires are banned, because it’s better to be safe than sorry.
• If you’re unsure about water availability, then pack extra water, because dehydration is a quick trip-ruiner.
• If you’re in bear country and don’t have a bear canister, then find a proper hanging spot, because your food is too tempting.
• If your tent fabric feels damp inside after a night, then open the vents more, because you need better airflow to reduce condensation.
• If you’re camping near a river, then check the water level and weather upstream, because flash floods are a real danger.
• If you find a great dispersed camping spot but it’s within 100 feet of a water source, then move on, because Leave No Trace principles matter.
• If you’re unsure about the legality of dispersed camping, then contact the local land management agency, because you don’t want to get cited.
• If you’re experiencing severe wind, then double-check all stake and guyline tension, because your tent’s stability depends on it.
• If you pack out more trash than you packed in, then you’re doing it right, because leaving a place cleaner than you found it is the goal.

FAQ

What exactly are PFAS chemicals?

PFAS stands for per- and polyfluoroalkyl substances. They are a group of man-made chemicals used in a lot of products for their resistance to water, grease, and stains. You’ll often see them referred to as “forever chemicals” because they don’t break down easily.

Why are PFAS used in tents?

Manufacturers use PFAS treatments on tent fabrics to make them waterproof and stain-resistant. This helps keep you and your gear dry in wet conditions and makes cleaning up easier. It’s a performance feature that many campers have come to expect.

Are all tents treated with PFAS?

No, not all tents contain PFAS. Many brands are moving away from using these chemicals due to growing environmental and health concerns. You can find tents specifically advertised as “PFC-free” or “PFAS-free.”

Are PFAS in tents dangerous?

There are ongoing studies and concerns about the potential health and environmental impacts of PFAS. While direct exposure from a tent is generally considered low, the chemicals can leach into the environment over time. Many people prefer to avoid them altogether.

How can I find a tent without PFAS?

Look for product descriptions that explicitly state “PFC-free,” “PFAS-free,” or mention alternative waterproofing treatments like DWR (Durable Water Repellent) that are not PFAS-based. Reading reviews and checking brand sustainability pages can also be helpful.

What are the alternatives to PFAS for waterproofing?

Brands are using various alternatives, including different types of DWR coatings that don’t rely on PFAS. Some tents use tightly woven fabrics with minimal coatings, relying on the fabric’s inherent properties for water resistance. Innovation in this area is ongoing.

Do PFAS treatments wear off over time?

Yes, like most DWR treatments, PFAS-based waterproofing can wear off with use, washing, and exposure to the elements. This is why tents might seem less waterproof after several seasons. Reapplying a PFAS-free DWR treatment can help extend a tent’s water resistance.

Is it okay to still use my old PFAS-treated tent?

This is a personal decision. If your tent is still functional and you’re not overly concerned, using it is fine. However, if you’re looking to replace gear or are concerned about environmental impact, consider PFAS-free options for future purchases.
