Wanderer Outdoor Watershed Backpack Black/Green/Yellow 32L *New* Black/Green/Yellow
Waterproof backpack with unspecified water-repellent coating; PFAS risk unclear.
Watershed backpacks use durable ripstop nylon with waterproofing, but the brand does not disclose coating chemistry. Most outdoor gear waterproofing contains PFAS; contact brand for specific details.

Material
Ripstop nylon with waterproof coating (type unspecified)
Brand disclosure
Brand is silent on PFAS
Lab data

Why this grade
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline
clothing is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
The full breakdown
What it's made of and why it matters
This pack uses ripstop nylon, a tightly woven polyester-nylon blend chosen for tear resistance and lightweight durability. The waterproof coating type is not disclosed by Watershed in available product specs. Without knowing whether the water-repellent coating (water-repellent coating) finish is fluorocarbon-based, wax-based, or paraffin-based, you cannot assess PFAS exposure risk or longevity of water resistance. Ripstop itself is stable, but the coating chemistry matters for both safety and function.
The brand's record and disclosure
Watershed is a smaller outdoor brand without published PFAS policies or third-party certifications (Bluesign, OEKO-TEX) readily available in public records. The company does not disclose water-repellent coating specifications on product pages, which is a red flag for transparency in a product category where PFAS-free alternatives now exist. No major safety recalls or contamination incidents are documented for Watershed products in the public domain.
How it compares in its category
Many mainstream outdoor brands (Patagonia, REI Co-op, Arc'teryx) now offer ripstop packs with disclosed PFAS-free or low-PFAS water-repellent coating coatings (often wax or paraffin blends). Watershed's silence on coating chemistry puts it behind market transparency standards. For a backpack at this price point, lack of disclosure is notably worse than competitors offering explicit PFAS-free labeling.
If you buy it
Store dry and away from direct heat and sunlight to slow coating degradation. Inspect seams and the outer surface annually for loss of water beading, which signals water-repellent coating failure. When water no longer sheets off, the coating has worn through; replacement is not practical, and the pack should be retired or used for dry goods only. Contact Watershed directly to ask about water-repellent coating type before purchase if PFAS exposure is a concern for your household.
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.”
Teflon-type coating/fluorocarbon in waterproof coating (water-repellent coating)
Ripstop nylon waterproof coatings commonly use C6 or C8 fluorocarbons for water repellency. Watershed does not disclose coating chemistry; PFAS exposure risk cannot be ruled out. (Graded separately as PFAS; noted here for completeness.)
Azo dyes in synthetic fibers
Ripstop nylon and polyester blends may use azo dyes in black, green, and yellow colorways. No specific safety incidents or reports are documented for Watershed packs. Most modern outdoor nylon does not use restricted azo dyes, but testing would be needed to confirm.
Antimony in polyester component
Ripstop often blends nylon with polyester; antimony trioxide is a common polyester catalyst. Levels in finished textiles are generally very low and stable, but migration has been documented in niche studies. Watershed does not disclose processing or finish specifications.
Formaldehyde resins in fabric treatments
Formaldehyde-based finishes can be used in ripstop for wrinkle resistance or mildew prevention. No public reports of formaldehyde finish use on Watershed packs; modern ripstop typically does not require such treatment due to nylon's natural properties.
VOC off-gassing from coating
Fluorocarbon and other synthetic water-repellent coating coatings may release volatile organic compounds, especially when new or exposed to heat. The unspecified coating makes assessment difficult. New packs should be aired outdoors before extended indoor storage to minimize inhalation exposure.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% 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.
