Environ Jacket
Skip until brand discloses water-repellent coating chemistry or provides testing.
Stio does not disclose PFAS status or water-repellent coating treatment type for the Environ Jacket. Most outdoor jacket waterproofing uses PFAS; verification is needed before purchase.

What Environ Jacket is made of, ingredients and materials
The Environ Jacket is nylon with a water-repellent coating (water-repellent coating) treatment, but Stio has not disclosed which water-repellent coating chemistry is used. Traditional water-repellent coating finishes have historically relied on PFAS compounds to achieve water and stain resistance; newer non-PFAS alternatives (wax-based, silicone, or fluorine-free systems) exist but require explicit confirmation. Nylon itself is a synthetic polymer with low migration risk under normal wear, but the water-repellent coating layer is where hazard concentration typically occurs.
What’s concerning
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
PFAS
Stio has not disclosed the specific water-repellent coating formulation. If legacy PFAS-based (perfluorooctanoic acid, perfluorooctane sulfonate), accumulation and persistence in the environment and body are documented. No test data is available for this product.
Source, ATSDR ↗Nylon microfiber shedding during washing
All synthetic textiles shed microfibers in the wash. Nylon is a known contributor to microplastic pollution in waterways. Washing in a microfiber-retention bag or mesh reduces release but does not eliminate it.
What’s reassuring
Formaldehyde / VOCs
Nylon apparel can use formaldehyde-based finishing agents, but Stio has not disclosed finish type for the Environ Jacket. No recalls or reports of problematic formaldehyde levels are on record for this model.
Source, ATSDR ↗Azo dyes (colorant hazard)
No evidence this jacket uses prohibited azo dyes, and Stio is not flagged for azo-dye violations. The standard risk applies only if dyes are non-compliant; unknown dye source is a general transparency gap, not a confirmed hazard.
How is this PFAS grade calculated?
The brand's record and disclosure
Stio has not made a public commitment to PFAS-free water-repellent coating or released third-party testing of this jacket's fluorochemical content. No major safety recalls or certifications (such as bluesign or GOTS) are on record for this model. The silence on water-repellent coating chemistry is a red flag in an era when responsible outdoor brands routinely disclose or eliminate PFAS in water-resistant apparel.
How it compares in its category
Outdoor nylon jackets with water-repellent coating are standard, but transparency varies widely. Competitors like Patagonia, Arc'teryx, and Rab now offer PFC-free (PFAS-free) water-repellent coating options and publish test results; Stio's lack of disclosure places it below industry leaders in this regard. The jacket itself is not unusual, but the opaqueness around its finish is a significant competitive disadvantage in consumer trust.
If you buy it
Wash separately in cool water with mild detergent; avoid fabric softeners and high heat, which can degrade the water-repellent coating layer. Line-dry to preserve water repellency. Expect water-repellent coating effectiveness to decline over 2-3 years of regular use; re-treatment products are available but should themselves be PFAS-free if sustainability is your concern. Consider contacting Stio directly to request water-repellent coating composition before purchase.
