Case-Mate Waterproof Phone Bucket Bag
Skip until brand discloses waterproof treatment chemistry or certifications.
Case-Mate does not publicly disclose the waterproof coating used on this bucket bag. Waterproof treatments often use PFAS; without transparency or third-party verification, risk cannot be assessed.

The full breakdown
What it's made of and why it matters
Case-Mate Waterproof Phone Bucket Bag uses synthetic fabric (likely polyester or nylon) with an unspecified waterproof treatment or coating. The brand does not disclose whether the water-repellent finish uses fluorinated compounds (PFAS-based) or fluorine-free alternatives. Waterproof coatings on textiles historically relied on PFAS because of their performance, but non-fluorinated options exist. Without transparency, the chemical identity of the coating remains a major unknown.
The brand's record and disclosure
Case-Mate (owned by ZAGG Inc., a subsidiary of Cambium Networks) has no publicly available statement on PFAS use in bags or accessories. The brand does not list waterproof treatment chemistry on product labels or websites. Case-Mate has issued no relevant certifications (Cradle to Cradle, OEKO-TEX, or PFAS-free claims) that would clarify coating safety. This silence is typical of mid-market accessory brands but leaves consumers without the information needed to assess waterproofing risk.
How it compares in its category
Waterproof phone and gear bags from competitors vary widely: some use PFC-free (non-fluorinated) coatings; others remain silent like Case-Mate. Premium outdoor brands (e.g., Patagonia, arc'teryx) increasingly disclose and transition away from PFAS-based water treatments. Budget to mid-tier brands like Case-Mate rarely provide this detail. A bucket bag is lower-body-contact (not a shirt worn for hours), which reduces dermal absorption risk compared to apparel, but does not eliminate PFAS leaching into water or hands.
If you buy it
Keep the bag away from heat (sunlight, car interiors) to minimize any coating degradation or off-gassing. Do not machine wash; hand rinse with cool water only, as hot water and detergents may compromise the waterproof coating and potentially mobilize coating additives. Inspect for pilling, cracking, or peeling annually; if the coating delaminates, the bag's water resistance fails and any chemical residue becomes more exposed. Avoid storing in damp enclosed spaces where microbial growth or mold could promote coating breakdown.
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 waterproofing (PFAS / PFAS "forever chemicals")
The waterproof coating chemistry is not disclosed. Fluorinated water-repellents have historically been standard for textile bags; if used here, PFAS may leach into hands, perspiration, or water contacting the bag. Fluorine-free alternatives exist but Case-Mate does not confirm which is used.
Synthetic dyes and azo dyes in fabric
No recalls or public reports of restricted azo dyes in Case-Mate bags. Standard polyester and nylon fabrics are typically dyed within regulatory limits, but third-party testing is not disclosed.
Coating degradation and leachates
As the waterproof coating ages or is exposed to UV, heat, or friction, it may peel, crack, or leach additives (plasticizers, polymers, catalysts) into water or skin. The unspecified coating chemistry means the identity of these potential leachates is unknown.
Microplastic shedding
Synthetic fabric bags can shed microfibers, especially when rubbed or washed. If the waterproof coating is polymer-based, flaking coating particles may also release microplastics into wash water or the environment.
Antimony in polyester
If the fabric is polyester with antimony catalyst (common in polyester production), levels in finished textiles are typically below concern thresholds. No specific testing or concerns have been reported for Case-Mate bags.
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.
