What are PFAs (Perfluoroalkyl substances) and PFCs (Perfluorocarbons)?

PFA / PFC Chemicals

Perfluorinated and Polyfluoroalkyl chemicals, commonly known as PFCs or PFAs, are frequently used in outdoor gear, including sleeping bags, to repel water, dirt, and oil from treated fabrics. However the CDC and other scientific organizations have linked PFCs and PFAs to various health issues, such as hormone disruption, developmental problems in children, and even cancer.

Perfluoroalkyl substances (PFAs) and perfluorocarbons (PFCs) are a group of man-made chemicals used in various industries, including the production of fluoropolymer coatings and products that resist heat, oil, and stains.

They’ve earned their nickname “forever chemicals” because of their persistence in the environment and resistance to degradation. These compounds have become increasingly concerning due to their potential for adverse health effects on humans via endocrine disruption as well as reports linking exposure with pregnancy-induced hypertension and reduced birth weight.

PFAs can accumulate in the food chain gradually entering our bodies through eating contaminated foods or drinking contaminated water which means these environmental pollutants may be subjecting us to long-term health risks like weakening the body’s response to vaccinations.

Why should we avoid PFAs and PFCs?

PFA / PFC Scientific Analysis

Perfluoroalkyl substances (PFAs) and perfluorocarbons (PFCs) are man-made chemicals used in a wide range of industries, including the textile industry. These chemicals are widely used in certain types of winter gear, such as sleeping bags, tents and lunch boxes, to improve their water repellency.

Despite these benefits, PFAs and PFCs have been linked to significant environmental contamination through leaching into the aquifer from manufacturing processes or shedding off clothes during use.

This has subsequently resulted in their accumulation throughout the food chain with possible adverse impacts on human health. Studies have shown that exposure to certain levels of PFAs can cause liver damage while higher exposure could be toxic.

Additionally, long term contact with a related group of compounds known as Per-and PolyFluoroAlkyl Substances (PFASs) has been correlated with immune system disruption and developmental delays in children.

This is not to say that using products with PFCs and PFAs are going to immediately harm you or make you sick. However, a large body of the medical research on the subject indicates that reducing exposure to these chemicals is better, especially for children and immunocompromised people.

Common uses of PFAs and PFCs in the textile industry, specifically in sleeping bags

PFAs and PFCs are commonly used in the textile industry to enhance certain properties that make fabrics more durable, resilient or breathable. In sleeping bags, these chemicals can be used as impregnating agents to provide water and stain resistance which increases their longevity.

They also work to help resist oils, alcohol and dirt while providing increased breathability. These chemicals are praised for their beneficial properties but come with risk of potential health risks should one be overexposed.

This is why many people opt for products labeled PFA/PFC-free in order to reduce their own level of exposure as well as help decrease environmental pollution when disposing of such products.

Explanation of how PFA/PFC-free sleeping bags are made

To provide consumers with a healthier and more eco-friendly sleeping solution, companies are creating PFA/PFC-free sleeping bags. These bags come without the use of per- and polyfluorinated chemicals (PFA/PFCs), which have been linked to various health issues such as testicular and kidney cancer, thyroid disease, obesity, weakened immunity.

Instead of using traditional DWR coatings that contain these harmful toxins to make the sleeping bag waterproof, alternative materials or treatments are used during the manufacturing process.

For instance, some brands utilize natural fibers or innovative fabric processes to achieve water repellency without chemical additives or flame retardants. This makes PFA/PFC free sleeping bags safe for everyone including children and those who may be highly sensitive to toxic chemicals.

How to Choose a PFA/PFC-Free Sleeping Bag

When it comes to choosing a PFA/PFC-free sleeping bag, opting for one that is non-toxic and environmentally friendly should be top priority. It’s important to research and select reputable brands that prioritize using nonhazardous materials such as natural fibers with no intentionally added PFAs or PFCs.

For example, Kelty offers responsibly constructed sleeping bags ethically sourced from safe materials like organic cotton and down free of puddle contaminants linked to serious health issues such as cancer and weakened immunity.

Outdoor clothing treated with alternative materials such as DWR (durable water repellent) provide water resistance without having to resort to use of chemically hazardous agents like PFAs or PFCs – making them the ideal choice when shopping for outdoor gear.

Benefits of PFC-Free Sleeping Bags

PFC-free sleeping bags offer several benefits, including reduced environmental impact, improved health safety, and the use of recycled materials.


Reduced environmental impact

Opting to purchase a PFC-free sleeping bag brings you one step closer ditching some of the harmful chemicals that are found in most outdoor gear. This is turn also helps to reduce environmental harm and pollution.

Outdoor brands that create PFC-free sleeping bags also break the myth that it’s necessary to use these chemicals for effective gear performance – paving way for a more sustainable future in the outdoor gear industry.


Safer for health

The health benefits of PFC-free sleeping bags means sidestepping the risk posed by perfluorocarbons (PFCs), and creating a safer sleep environment.

By choosing low-impact and hypoallergenic sleeping bags, you also protect yourself against potential irritations or allergic reactions as well—another definitive plus point in making the switch to green options.


Use of recycled materials

PFC-free sleeping bags are not only better for the environment and your health, but they also often incorporate the use of recycled materials. By choosing a sleeping bag made from recycled materials, you’re making an eco-conscious choice that helps reduce waste and decrease the demand for new resources.

Thus, when you choose a PFC-free sleeping bag, you’re not just prioritizing your comfort but also supporting the circular economy.

1. What is a PFA-free and PFC-free sleeping bag?

PFAs (Perfluoroalkyl substances) and PFCs (Perfluorocarbons) are chemicals that are often used to waterproof sleeping bags and other outdoor gear. These hazardous chemicals are known as “forever chemicals”, because they never degrade and keep bioaccumulating (building up) in the environment over time. A PFA/PFC free sleeping bag is made without PFA, PFOA, PFC and PFO.

2. Are PFA / PFC-free sleeping bags as effective at repelling water and stains?

Yes, PFC-free sleeping bags can still provide good water and stain resistance. Manufacturers like the Patagonia, Sierra Nevada and Big Agnes have created alternative waterproof treatments like PFC-free moisture repellent coating without the use of forever chemicals.

3. Can I still use a conventional water repellent if my sleeping bag is PFAs/ PCFs free?

Yes, it is possible to use a conventional water repellent if your sleeping bag is PFAS/PFC-free. However, since many conventional water repellents often contain PFAS/PFC, make sure to use a non-toxic solution that is free of these chemicals.

4. How do I care for a PFA / PFC-free sleeping bag?

Caring for a PFC-free sleeping bag is similar to caring for any other type of sleeping bag. It is recommended to follow the manufacturer’s instructions for cleaning and storing the bag properly to ensure its longevity and performance.
