REI Co-op Packmod Rainshield Pocket
water-repellent coating treatment PFAS risk unknown; REI provides no disclosure.
REI Co-op gear often uses water-repellent coating finishes to shed water. The brand does not publicly disclose whether this pocket uses PFAS-based or PFAS-free water repellents, making it a moderate concern item.

The full breakdown
What it's made of and why it matters
This is a nylon fabric pocket treated with a water-repellent coating (water-repellent coating) finish. Nylon itself is a synthetic polymer with a well-established safety profile for apparel use. The water-repellent coating treatment is the variable: it can be applied using fluorinated compounds (which carry PFAS concerns) or newer fluorine-free alternatives, but REI does not specify which chemistry was used on this pocket. Without transparency, you cannot assess whether the water-repellent coating contains legacy PFAS like PFOA or newer replacements.
The brand's record and disclosure
REI Co-op has not made public commitments to PFAS-free water-repellent coating treatments across its apparel lines, nor does it disclose the chemistry of treatments on individual products like this pocket. The brand markets sustainability and has phased some hazardous chemicals, but remains silent on fluorinated water-repellent coating specifically. This silence is common in outdoor retail but represents a gap in transparency that prevents informed choice.
How it compares in its category
Outdoor apparel pockets with water repellency are standard across brands (REI, The North Face, Patagonia, etc.), and most do not disclose water-repellent coating chemistry. Patagonia and some premium brands have begun adopting fluorine-free water-repellent coating (like wax or silicone-based) and state it openly; REI has not matched this transparency. For a basic pocket, the performance difference between fluorinated and fluorine-free water-repellent coating is minimal in real-world use.
If you buy it
Treat it as you would any outdoor nylon gear: wash occasionally in cool water with mild detergent, air dry, and avoid prolonged heat exposure or high-temperature washing. The water-repellent coating will degrade over 1-2 years of regular use and rewashing; this is normal and does not increase hazard risk. If PFAS exposure concerns you, consider contacting REI directly to request water-repellent coating chemistry disclosure before purchase, or choose alternatives from brands with published fluorine-free commitments.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Fluorinated water-repellent coating (PFAS precursor)
Nylon pockets are commonly treated with fluorinated water repellents (Teflon-type coating-based or legacy PFOA chemistry). REI provides no disclosure, so fluorine presence is unconfirmed. Dermal contact with treated fabric poses minimal acute risk, but manufacturing and end-of-life disposal are PFAS exposure pathways.
Formaldehyde resins in finishing
No evidence of formaldehyde-based finishes specific to REI nylon pockets. Standard nylon apparel rarely contains formaldehyde resins, though some dyes or sizing compounds may introduce trace levels. Not a primary concern for this product category.
Azo dyes and synthetic colorants
REI Co-op apparel has not been flagged for azo dyes in published testing or recalls. Nylon pockets are typically dyed with modern azo or reactive dyes that meet OEKO-TEX or similar standards, though REI does not certify this pocket independently.
Antimony in polyester blends
This pocket is nylon, not polyester, so antimony catalyst residues are not a concern. Nylon uses different polymerization chemistry that does not require antimony.
Coating degradation and microfiber shedding
water-repellent coating coatings break down with washing and wear, shedding microscopic particles into water and soil. This is an environmental hazard rather than direct human toxicity risk, but repeated washing will accelerate water-repellent coating loss and eventual synthetic textile fragmentation over years of use.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 42% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
