All 15 sleeping bags we scored fail our PFAS screen
All 15 sleeping bags 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 sleeping bags non-toxic?
None of the 15 sleeping bags 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 sleeping bags in this category are microplastics, VOCs and off-gassing, formaldehyde, artificial dyes, undisclosed ingredients.
Why Patagonia Fitz Roy Down Sleeping Bag 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 sleeping bags 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 3 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 1 more, meaning nobody has ruled it out. NCI
- Artificial dyes
Synthetic colours added to food, cosmetics and textiles, most of them petroleum derived.
Plausible but unconfirmed on 1 more, meaning nobody has ruled it out. FDA
- Undisclosed ingredients
Not a chemical. The absence of one, where we found no statement from the brand about what it uses.
Plausible but unconfirmed on 1 more, meaning nobody has ruled it out. FTC

How can you tell if sleeping bags contain PFAS?
In this category we check for BPA & bisphenols, phthalates, microplastics. Plastic-hardening chemicals linked to hormone disruption. Language like stain resistant, water repellent or easy release usually means fluorinated chemistry even when PFAS is never printed on the box.

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.
Do you lab test sleeping bags?
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.
