What Spigen says and does about PFAS
Spigen publishes a materials field and a Proposition 65 warning on each product, which makes the gap easy to see. It never uses the words fluoroelastomer or fluororubber anywhere on its own site, and a site search for PFAS returns only product listings. On one watch band it names nylon and warns about nickel and bisphenol A. On its current Pixel Watch band the materials field says only fabric. A university study of 22 watch bands found elevated PFAS in nine, tied to fluoroelastomer construction, but named no brands.
- MaterialsOn its Apple Watch Band Lite Fit, Spigen names the material as nylon and carries a Proposition 65 warning naming nickel and bisphenol A. No PFAS chemical appears in that warning. Spigen ↗
- StudyA University of Notre Dame study of 22 fitness tracker and smartwatch bands found elevated perfluorohexanoic acid in nine of them and tied the results to bands made using fluoroelastomers. It named no brands, so no result is attributed to this brand. University of Notre Dame ↗
- StudyThe same study reported that elevated results were more common in bands costing more than about fifteen dollars, which is the only lens its published findings offer on aftermarket band brands. University of Notre Dame ↗
