Spigen A603 Waterproof Bag
Wait for coating details, waterproof bags often contain PFAS water-repellent coating.
Spigen keeps waterproof coating chemistry secret on this synthetic fabric bag. Waterproof bags typically depend on water-repellent coating finishes that may contain PFAS, and no PFAS-free certification exists.

What Spigen A603 Waterproof Bag is made of, ingredients and materials
The Spigen A603 uses synthetic fabric (likely polyester or nylon) with an applied waterproof coating of undisclosed composition. The coating is the critical unknown, most waterproof textiles are treated with either PFAS-based water-repellent coating (water-repellent coating) finishes or polyurethane/silicone alternatives. Since Spigen has not publicly specified the coating chemistry, you cannot confirm whether legacy PFAS chemicals (like PFOA) or newer "forever chemicals" are present. The fabric itself poses minimal chemical risk; the coating is where hazards concentrate.
What’s concerning
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.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
PFAS
Unspecified waterproof coating on synthetic fabrics commonly uses PFAS-based water-repellent coating treatments in budget models. Spigen has not disclosed coating type, making PFAS presence impossible to rule out. Direct skin contact during normal use is low-risk, but manufacturing and disposal may release PFAS.
Source, ATSDR ↗Coating degradation and microparticle shedding
Over time, polyurethane or silicone coatings on waterproof bags can crack, peel, or shed fine particles into packed items. If the coating contains particulate fillers or pigments, shed material could contaminate food or sensitive gear. Spigen has not published durability test data or expected service life.
Odor/VOC off-gassing from coating
New waterproof bags often emit chemical odors from solvent residues in applied coatings. This is typically a temporary nuisance (days to weeks) and not acutely hazardous, but suggests incomplete curing or volatile components in the finish.
What’s reassuring
Synthetic fabric dyes and finishes
Polyester or nylon in the base fabric may be treated with azo dyes or antimony catalysts; Spigen has not disclosed dye chemistry. For a waterproof bag not in direct prolonged skin contact, risk from textile dyes is low compared to apparel.
Metal hardware corrosion and leaching
If the bag includes zippers or buckles, corrosion under wet conditions could release trace metals; no incidents reported for Spigen bags. Stainless steel or anodized aluminum fittings minimize this risk.
How is this PFAS grade calculated?
The brand's record and disclosure
Spigen is a mobile-accessory maker with no established pattern of detailed materials disclosure for non-phone products. The company has not published a PFAS-free commitment or third-party test reports for this bag. Spigen's silence on coating chemistry is typical for consumer electronics brands moving into gear, but it means you lack transparency needed to assess your exposure. No recalls or contamination incidents are on record for Spigen bags.
How it compares in its category
Waterproof bags from established outdoor brands (e.g., Osprey, Sea to Summit) often disclose PFAS-free coatings or provide test certificates. Mass-market alternatives from less transparent makers carry the same unknown-coating risk as this Spigen model. Budget waterproof bags rarely volunteer coating details. If PFAS exposure matters to you, this product sits in the middle of the disclosure spectrum, not worse than generic alternatives, but worse than transparency-leader brands.
If you buy it
Store the bag in a cool, dry place away from heat and direct sunlight to slow coating degradation. Inspect the fabric seams and coating annually for cracks or peeling; once the waterproof layer fails, replace the bag rather than attempting repair (resealing may not work). Do not machine wash; use a damp cloth and mild soap on the exterior. Before purchase, email Spigen support to request the safety data sheet (SDS) for the waterproof coating; their answer will tell you whether they know their own supply chain.
