Akona Gobi XL Dry Phone Case
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes proprietary polymer dry bag, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

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.
Polymer degradation over time
Proprietary polymers used in dry bags can become brittle or develop micro-cracks after repeated UV exposure or thermal cycling, reducing waterproof integrity. No data is available on the specific polymer's long-term durability or how Akona addresses this.
Volatile organic compound (VOC) off-gassing
Proprietary polymers may release minimal VOCs during manufacturing or initial use, especially if the case is new and stored in warm conditions. No specific VOC testing or limits are published by the brand; off-gassing risk is typical of the dry-bag category.
Microorganism or bacterial growth inside sealed environment
If the case traps moisture inside without proper ventilation after closure, internal condensation could create a humid microenvironment. This is not a material hazard but a usage risk; ensure phone is dry before sealing and allow occasional air circulation.
Closure seal integrity loss
The waterproofing depends entirely on the integrity of the closure mechanism and seams. Manufacturing defects, wear, or debris preventing a full seal could compromise water resistance without visible damage to the polymer itself.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Leachates from polymer base material
No reports of harmful chemical leachates from Akona's proprietary polymer into electronics or skin contact. Standard synthetic polymers used in dry cases do not typically contain bisphenols or phthalates, though complete material composition is not disclosed.
The full breakdown
What it's made of and why it matters
The Akona Gobi XL uses a proprietary polymer dry bag material, which typically refers to a thermoplastic elastomer or similar synthetic polymer engineered for water resistance without added fluorinated coatings. This construction method avoids the need for Teflon-type coating or other hazardous water-repellent treatments that would introduce chemical leaching risk. The material is designed to create a seal through closure mechanism and inherent hydrophobic properties of the polymer itself, not a surface treatment.
The brand's record and disclosure
Akona has no documented history of product safety recalls or chemical disclosure controversies on record for this product line. The brand maintains silence on broader PFAS practices and chemical sourcing, which is typical for small-to-mid-tier case manufacturers. No third-party certifications (e.g., Oeko-Tex, GreenGuard) are known to apply to this product, and the brand does not publish material safety data sheets publicly for the proprietary polymer.
How it compares in its category
Waterproof phone cases vary widely, some use PVC (chlorine-release risk), others rely on Teflon-type coating or silicone coatings (PFAS concerns or volatile off-gassing). The Akona's polymeric dry-bag approach is a middle ground, avoiding known synthetic finishes while relying on the inherent water-resistance of its base material. Most competitors in the casual dry-case segment share similar uncoated polymer construction, making this product representative of the category rather than an outlier.
If you buy it
Store the case in a cool, dry place away from direct sunlight to slow polymer degradation over years of use. Do not expose it to sustained heat above 60C (140F), as polymers can soften and lose seal integrity. Inspect the closure mechanism and seams regularly for cracks or wear; replace the case if seals visibly degrade or fail water tests. Avoid contact with solvents, oils, and perfumes, which can compromise the polymer's hydrophobic properties.
