PFAS in Life Jackets: Safe Personal Flotation Devices

Life jackets are supposed to keep your family safe on the water. But a lot of PFDs (personal flotation devices) use PFAS-based treatments in their fabric, foam, and webbing. So every time someone straps one on, they’re wearing forever chemicals against their skin. It’s one of those categories most people never think to check.

Where PFAS Hide in Life Jackets

Life jackets are built to repel water. That’s their whole job. And the way most manufacturers get there is through fluorinated DWR (durable water repellent) coatings on the outer shell fabric. But that’s not the only place PFAS show up. The closed-cell foam inside may contain fluorinated additives to resist water absorption over time. The webbing and buckle straps sometimes carry surface treatments too. Even the inner lining fabric can be treated for moisture management. So you’re looking at multiple layers of potential exposure, not just the outer shell.

Research in eBioMedicine found that routine consumer product exposures add up to measurable PFAS levels in blood. Most PFAS exposure happens through what we eat, drink, and breathe rather than through the skin, but a life jacket worn against wet skin for hours, often with snacks and wet hands going to the mouth, is the kind of all-day contact worth reducing where you can.

Why PFAS Exposure from Life Jackets Matters

Life jackets get a lot of contact time, usually on warm days when kids are in and out of the water with wet skin and snacky hands. Kids are the bigger concern here. They wear life jackets for longer stretches, they put their hands to their mouths more, and their smaller bodies mean any given exposure counts for more pound for pound.

Think about it this way: a rain jacket might be on for an hour. A life jacket at summer camp? All day. That kind of sustained contact, in the sun, with wet skin, is a different level of exposure than most gear categories.

How to Choose a PFAS-Free Life Jacket

Not every PFD is loaded with PFAS. Here’s what to look for when shopping:

• Ask the manufacturer directly whether they use fluorinated DWR treatments on their life jackets. Brands that have moved to fluorine-free alternatives will usually say so.
• Look for PFDs with inherently buoyant foam (like PVC or PE foam) rather than those marketed as having “enhanced water resistance” in the foam itself, which may signal chemical treatment.
• Paddling-specific PFDs from brands like Stohlquist, NRS, and Astral tend to publish more detailed material information than general-purpose recreational vests.
• Check for OEKO-TEX Standard 100 or bluesign certification, which restrict PFAS use in textiles.

The Stohlquist Drifter PFD is popular with kayakers and paddlers for good reason. Stohlquist has been making PFDs for decades, and the Drifter uses PE foam for flotation. It has ventilated shoulder pads and an open-side design, so it doesn’t turn into a sauna on a hot day the way a lot of cheap recreational vests do.

Tips for Reducing PFAS Exposure from Water Safety Gear

Even with the life jacket you already own, you can cut down on exposure:

• Wear a rash guard or thin base layer underneath. It puts a barrier between the treated fabric and your skin.
• Rinse life jackets with fresh water after each use and hang them to dry. This washes off surface residue before it builds up.
• When the outer fabric starts to crack or peel, replace the vest. Degraded DWR coatings can release more chemicals than intact ones.
• Store PFDs somewhere ventilated, not sealed in a hot boat compartment where heat speeds up off-gassing.
• For kids who wear a life jacket every day at camp, a PFAS-free vest is worth the money. A full summer of daily use adds up fast.

Frequently Asked Questions

How do I know if my life jacket contains PFAS?

Without lab testing, you can’t be 100% certain. But there are clues. If the outer fabric has a slick, water-beading finish, it likely has a DWR coating that may be PFAS-based. Check the product listing or manufacturer’s website for terms like “water-repellent,” “durable water repellent,” or “DWR treated.” You can also contact the manufacturer directly and ask whether they use fluorinated or fluorine-free DWR. Brands that have switched to PFAS-free alternatives are usually happy to say so.

Are PFAS-free life jackets as effective as treated ones?

Yes. PFAS treatments affect the outer fabric’s water repellency, not the buoyancy. A life jacket’s flotation comes from the foam inside, which works the same whether the outer shell is treated or not. A PFAS-free PFD might absorb slightly more water into the outer fabric, making it marginally heavier when wet, but the difference is negligible and doesn’t affect safety performance. All USCG-approved life jackets meet the same buoyancy standards regardless of surface treatments.

Do all life jacket brands use PFAS in their products?

No. While PFAS-based DWR has been the industry standard for years, several outdoor and paddling brands have started transitioning to fluorine-free alternatives. The shift is happening fastest among specialty paddling brands and slower among mass-market recreational vest manufacturers. The best approach is to ask the specific brand about their chemical policy, since even within a single brand, some product lines may be PFAS-free while others are not.
