All 15 rain pants we scored fail our PFAS screen
All 15 rain pants 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 rain pants non-toxic?
None of the 15 rain pants 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 rain pants in this category are microplastics, VOCs and off-gassing, formaldehyde, heavy metals.
Why Patagonia Women's Torrentshell 3L Pants 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 25 points between the top and the bottom of this rain pants 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.

- VOCs and off-gassing
Volatile compounds that evaporate out of a material at room temperature, which is what a new product smell is.
Plausible but unconfirmed on 2 more, meaning nobody has ruled it out. EPA
- Formaldehyde
A preservative and resin ingredient that is also released slowly by a group of chemicals used in its place.
Plausible but unconfirmed on 2 more, meaning nobody has ruled it out. NCI
- Heavy metals
Metals such as antimony, nickel and chromium migrating from a material into what touches it.

See PFAS-free rain pants on AmazonWhat the evidence says about PFAS in rain pants
California has banned regulated PFAS in most new textiles since January 2025, but gives outdoor apparel for severe wet conditions until January 2028, requiring a Made with PFAS chemicals disclosure in the meantime. Colorado has required disclosure on such apparel since January 2025, and Maine will require the same disclosure from January 2029. The European Commission adopted a restriction in 2024 banning PFHxA in consumer textiles such as rain jackets. In testing released in 2022, the advocacy group Toxic-Free Future found PFAS in 9 of the 13 jackets it tested that were labeled stain or water resistant.
- Regulatory filingCalifornia’s AB 1817 has banned regulated PFAS in new textile articles since January 1, 2025, but does not apply the ban to outdoor apparel for severe wet conditions until January 1, 2028, which until then must carry a Made with PFAS chemicals disclosure. California Legislature ↗
