The Science: Understanding the Risks of Traditional Winter Gear
Many traditional winter garments contain harmful chemicals known as PFAS (Per- and polyfluoroalkyl substances). Think of PFAS as an invisible, permanent raincoat that's sprayed onto fabrics to make them repel water and stains. While effective, the problem is that this chemical "raincoat" doesn't break down and can leach off the fabric and into our bodies and the environment.
Health Risks of PFAS
According to the National Academies of Sciences, Engineering, and Medicine, PFAS exposure has been linked to various health issues. Children are particularly vulnerable due to their developing bodies, lower body weight, and longer potential exposure time over their lifespans. Documented risks include:
- Developmental problems in children
- Weakened immune system & Reduced vaccine efficacy
- Thyroid disease & Hormonal disruption
- Certain cancers (including testicular and kidney)
- Elevated cholesterol levels, asthma, and liver problems
Environmental Concerns
- PFAS are known as "forever chemicals" because they do not break down in the environment, leading to widespread contamination of water and soil, as documented in Environmental Science & Technology.
- They can enter the food chain and have been found in wildlife across the globe, including polar bears.
How Common Are PFAS in Kids' Clothes?
Recent studies show a concerning prevalence of PFAS in children's outerwear:
- A CHEM Trust study found PFAS in **64% of 72 clothing samples** tested.
- Research by Environmental Defence Canada found that a shocking **91% of tested children's gloves** contained these harmful chemicals.
Your Quick Shopping Checklist: What to Look For in Sustainable Winter Gear
Navigating labels can be confusing. Here’s a detailed guide to the most important features and certifications that ensure your child's gear is safe, durable, and sustainable.
For Winter Coats and Snow Pants
- PFAS-Free Water Repellency: Look for explicit terms like "PFAS-Free," "PFC-Free DWR," or brand-specific technologies like BIONIC-FINISH® ECO.
- Recycled Materials: Choose outer shells made from recycled polyester or nylon, ideally with Global Recycled Standard (GRS) certification.
- Non-Toxic Insulation: Opt for Responsibly Sourced Down (RDS) or high-quality recycled synthetic insulation like PrimaLoft®.
- Durable Construction: Look for reinforced seams and adjustable features for growth ("grow-with-me" sleeves and legs).
For Base Layers
- Natural Materials: Merino wool is the gold standard for its warmth, moisture-wicking properties, and odor resistance. Look for ZQ or Responsible Wool Standard (RWS) certifications. Organic cotton is another good option.
- Safety Certifications: OEKO-TEX® Standard 100 certification ensures the fabric is free from a long list of harmful substances.
For Mittens, Gloves & Boots
- PFAS-Free Waterproofing: Just like with coats, this is the most crucial feature for keeping hands and feet dry without harmful chemicals.
- Durable, Non-Toxic Soles: For boots, look for natural rubber soles with good grip for traction on snow and ice.

How to Make Gear Last Longer: A Minimalist & Sustainable Approach
Choosing sustainable gear is the first step. The next is making it last. A mindful approach reduces waste, saves money, and teaches valuable lessons about consumption.
Smart Tips for Longevity
- Size Up (Within Reason): Buying coats or snow pants one size larger can often get you a second season of wear. Look for adjustable cuffs to keep sleeves and legs from dragging.
- Look for 'Grow-With-Me' Features: Many brands like Polarn O. Pyret, North Face, and Burton build in special seams that can be let out to extend the length of sleeves and pant legs.
- Choose Gender-Neutral Colors: Opting for versatile colors like navy, green, grey, or red makes it easy to hand gear down to younger siblings, regardless of gender.
- Care for It Properly: Follow washing instructions carefully. Use a gentle, eco-friendly detergent and re-apply a non-toxic water-repellent spray (like Nikwax) once a season to maintain performance.
- Repair, Don't Replace: A small tear doesn't mean the end. Keep a gear repair patch (like Tenacious Tape) on hand for quick, durable fixes to extend the life of your investment.
Frequently Asked Questions
Is PFAS-free winter gear more expensive?
While some high-performance brands have a premium price, this is often due to their overall quality and durability, not just their non-toxic status. Brands like Quince have proven that it's possible to get affordable, high-quality, PFAS-free gear. We recommend viewing it as an investment; a well-made, durable coat that lasts for multiple seasons and can be handed down is often more economical in the long run than a cheaper alternative that needs to be replaced every year.
What's the difference between PFC-free and PFAS-free?
These terms can be confusing! PFAS is the broad family of "forever chemicals." PFCs (perfluorinated chemicals) are a large subgroup within the PFAS family. For consumers, **"PFAS-free" is the gold standard** as it means the entire class of chemicals has been avoided. "PFC-free" is also a very strong indicator of a safer product, and brands often use the terms interchangeably. The key is to look for an explicit statement that the product is free from these fluorinated compounds.
Is recycled polyester safe for kids' winter coats?
Yes, recycled polyester from a reputable brand is a safe and highly sustainable choice. The recycling process for materials used in children's clothing is well-regulated to ensure safety. Certifications like the **Global Recycled Standard (GRS)** and **bluesign®** provide an extra layer of assurance that the material is free from harmful substances and was produced in an environmentally responsible way.
How can I tell if older, hand-me-down winter gear has PFAS?
Unfortunately, it's almost impossible to tell just by looking. As a general rule, if an older garment (pre-2020) is highly water- and stain-resistant, it's very likely it was treated with PFAS. While these items are still functional, you can create a safer barrier by layering a high-quality, non-toxic merino wool base layer underneath to minimize direct skin contact.
