PFAS-Free Waterproof Jackets: Alternatives, Performance and Sourcing Questions

Un PFAS-free waterproof jacket is more than just a waterproof finish with a catchy name. You need to know which parts of the jacket the claim refers to, what evidence supports the claim and how the garment actually performs. Water-repellent treatments, membranes and sealed seams all have different functions and thus one does not necessarily prove the other. The brief needs to link the chemical requirements with tests and production control.

What Does PFAS-Free Mean for Waterproof Jackets?

“PFAS-free” is a claim that needs to be more clearly defined. This claim can refer to the finish, the material or even the finished product. The evidence provided to support this claim will most likely vary between these. The buyer needs to establish the specific requirements prior to comparing supplier proposals.

How Is a PFAS-Free Finish Different From Waterproof Construction?

A durable water-repellent finish allows water to form beads on a surface and roll off it. The material barrier of a membrane or coating and the seal of the seams are two other important features. A PFAS-free water-repellent finish or membrane does not necessarily mean that the entire garment is waterproof. Also, the fact that a garment has a membrane does not necessarily mean that all components are PFAS-free.

When a supplier quotes “PFAS-free waterproof jacket,” make sure this is a defined product requirement as opposed to a number of technical claims being bundled together. Define whether face-fabric finish, membrane or coating, seam tape, zip mer details and other components have been assessed by the supplier and what their findings were.

What Evidence Supports a PFAS-Free Jacket Claim?

For declarations, please request a list of covered articles, suppliers and respective versions. For test reports, please request a description of the scope of the testing, the method of testing, the analytes tested for, the detection limits for each test and the sample that was actually tested. A report for one fabric does not automatically include tests for trims, threads, prints, zippers, etc., nor tests performed on later substituted goods.

When verifying claims in evidence, make sure the wording of the claim is covered. ‘No intentionally added PFAS’ and a laboratory test report for selected substances are not the same. Ensure that you do not promise more than is contained in the documentation and check the requirements for each market where your products are being sold, as some claims may require legal approval.

For each of the PFAS-free waterproof jackets listed, record whether the claim has been made for the raw material, the component or the finished product.

Which PFAS-Free Waterproof Jacket Alternatives Should Brands Consider?

Alternatives need to be evaluated as complete material systems. A material family or “non-fluorinated” label alone does not prove chemical status, water protection or suitability for the intended use.

What Can Non-Fluorinated Water-Repellent Finishes Offer?

Alternative non-fluorinated finishes for surface water repellency may offer a solution for certain products. Test the finish for performance, test against the product’s exposure, test against the product’s care and test against the fabric construction. Ask about application, ask if the sample is the same as production and ask for evidence of performance after care washes/wears.

Assume nothing about the finishes listed here. Specify water repellency, hand, durability and care requirements in the PFAS-free waterproof jacket brief. A light rain jacket will require a different set of targets than the wet weather use jacket.

Can PU or TPU Be Used in a PFAS-Free Waterproof Jacket?

PU- and TPU-coated or laminated textiles are sometimes advertised using these terms. However, PU and TPU do not automatically mean PFAS-free. Textiles must be checked for exact layers and finishes and supplier documentation requested to confirm the chemical composition.

A membrane or coating does not replace checks on seams, closures and garments. Validate the water protection, breathability, flexibility, care and durability of the selected material and sample. No single membrane provides a solution to all of these requirements.

How Should Brands Evaluate PFAS-Free Waterproof Performance?

Chemical documentation and garment performance data address different questions. Therefore, keep the corresponding records with the respective material and product version that has been approved.

Which Water-Protection Tests Should a PFAS-Free Rain Jacket Pass?

The intended use and rain exposure must be clearly defined. The assessment of waterproofness may include the surface water repellency, the water column pressure of the material and the water tightness of seams and openings. The test method, the test specimens and the acceptable test results must be clearly defined prior to the test. Results obtained by different test methods are not comparable.

For a PFAS-free waterproof jacket, evaluate the finish on the relevant fabric and check the assembled garment at potential entry points. Record whether the tested sample includes the proposed print, coating, seam tape, zipper and lining. Do not apply a base-fabric result automatically to a different jacket construction.

How Do Breathability, Care and Durability Affect Selection?

Additional characteristics to consider for a PFAS-free waterproof jacket are vapor transfer, weight, abrasion, flexing and wash/dry care. Decide which characteristics need to be tested and which only need to be reviewed using samples. Test/assess the finish after relevant care or wear where applicable. Water-repellency testing does not test for waterproofness or for any PFAS content.

What Should Buyers Ask When Sourcing PFAS-Free Waterproof Jackets?

Clearly define the scope for a chemical, the construction approval process and the approval responsibilities. This will help to avoid questions that could render a material change to be out of scope and thus invalidate evidence.

What Chemical and Product Documents Should a Supplier Provide?

Please supply a component-level material list, Finish and Construction declarations, relevant reports and the tested sample identity. Clarify the method of advising of any changes to finish, mill, membrane, seam-tape or trim. Verify that bulk materials are identical to the approved version and that all applicable market requirements have been reviewed.

Keep separate records for the chemical requirements of a PFAS-free waterproof jacket and the performance requirements. It will help you to see whether a test supports a chemical statement or a water-protection claim or both. General supplier assurance is not enough and must be supported by the documents required by your brand’s compliance process.

How Can Brands Control Changes Before Bulk Production?

Sampling can move from CAD paper patterns through to contrast or fit samples and iterative samples as necessary. A pre-production sample is made from approved bulk fabric and approved accessories. Manufacturing involves product inspection on the production line before goods are delivered.

This connects material selection with the garment supplied.

MOQ, delivery and payment terms will be advised upon our initial inquiry.

For a PFAS-free waterproof jacket, sample approval does not confirm the chemical composition. Ensure that all declarations and reports are linked to the correct version number. Check for any substitutions and confirm that any earlier approved evidence is still valid.

Fabric swatch books can offer a selection of materials. Sizes, colors, fabrics, styles, labels and logos can all be altered to suit your requirements. We use original designs, samples or photographs as reference points for your development.

Options must be tested against the PFAS requirement and cannot be taken as sufficient on the basis of other criteria.

Verify the specific PFAS status and performance for the proposed material and garment; existing rainwear specifications do not necessarily mean PFAS-free.

FAQ (questions fréquentes)

Q: Is a PFAS-Free Waterproof Jacket Still Waterproof?

Designing a water-protection garment is possible but the claim depends on the material mix used for the garment as well as the design of the garment. Claims on waterproof garments have to be checked on fabric, seams and openings against agreed requirements. The PFAS status of a garment does not say anything about the waterproof performance of the garment.

Q: Does a Non-Fluorinated Finish Alone Make a PFAS-Free Waterproof Jacket?

A: No. Find out the scope of the supplier’s declaration and whether the finish is covered or not. Finish description does not necessarily mean chemical assessment for the whole product.

Q: What Should Buyers Request From a PFAS-Free Waterproof Jacket Supplier?

A: Request component-level material information, declarations and applicable test reports that identify the scope and sample. Also agree on change notification, performance testing and approval records before bulk production.
