All 15 stain-resistant suits we scored fail our PFAS screen
All 15 stain-resistant suits PFAS Authority has graded score below its 70 point pass mark for PFAS and other toxins, as of October 2026.
Every grade below is built from published materials, ingredient lists, certifications and brand disclosures, scored on one public rubric and ranked best-graded first. Each score links to the full breakdown of what earned it, and the numbers across the whole dataset are published too.
Are stain-resistant suits non-toxic?
None of the 15 stain-resistant suits we graded clear our screen. Non-toxic is not a defined or regulated term, so what we can tell you is what our graders recorded. Beyond PFAS, the hazards found or left unruled-out on stain-resistant suits in this category are microplastics, artificial dyes, formaldehyde, heavy metals, undisclosed fragrance.
Why J.Crew Women's Linen-Blend Schoolboy Blazer grades highest here, and why that is not a pass
Every grade on this page is one sum. A category starts from a baseline, each disclosed material or coating adds risk points, and each thing the brand or a third party has published takes them away. Below is that sum for the winner, then for 1 product it beats, so you can see exactly where the 45 points between the top and the bottom of this stain-resistant suits ranking come from. Nothing in this category reaches our 70 point pass mark, so this is the shape of the field rather than a recommendation.

What we check on stain-resistant suits
- Confirmed PFAS, PTFE or fluoropolymer content, which is the heaviest penalty we apply.
- Stain, water or grease resistant treatments, which usually mean fluorinated chemistry.
- Whether the brand discloses what is in the product, or stays silent behind a “clean” claim.
- Independent lab results and certifications where they exist.

The stain-resistant suits brands we found no PFAS statement from
We found no PFAS statement from 2 of the brands here. That is our research, not proof a brand has never said anything, and it is not evidence of harm. It is why none of them score well on disclosure.
Banana Republic, J.Crew.
The brands that have published something, and what each of them actually said, are in our record of what every brand has said about PFAS.

Are stain-resistant suits non-toxic?

Beyond PFAS, the hazards found or left unruled-out on stain-resistant suits in this category are microplastics, artificial dyes, formaldehyde, heavy metals, undisclosed fragrance.
Which stain-resistant suits should I avoid?
The three lowest scoring we hold are Banana Republic Women's Slim City Stretch Blazer at 20, Banana Republic Women's Slim Refined Blazer at 20, J.Crew Men's Ludlow Slim-fit Suit Jacket at 20. The problem with the first is that stretch blends often use fluorine-based finishes; treatment unknown.

We found no PFAS statement from 2 of the brands we scored in this category, including Banana Republic, J.Crew. That is what our research turned up, not proof a brand has never said anything, and a missing statement is not evidence of harm. It is the reason those brands cannot score well on disclosure.

No. We score from published ingredient lists, materials, certifications, disclosures and third party lab results where they exist. Where a product has been independently tested we use that result and say so.
