Skip until brand discloses materials and PFAS status.
Onn provides no material composition or PFAS disclosure for this pouch. Waterproof pouches often use water-repellent coating-treated fabrics that may contain PFAS, but Onn's silence prevents assessment.

What Waterproof Pouch Lanyard, Black is made of, ingredients and materials
This pouch is constructed from polyester or nylon fabric with sealed seams, materials commonly chosen for water resistance and durability in portable storage. Neither polyester nor nylon inherently requires chemical surface coatings to repel water at the fabric level; water resistance here derives from the weave density and sealed seam construction. However, the critical unknown is whether a fluorocarbon (PFAS-based) or non-fluorinated water-repellent finish has been applied during manufacturing to enhance performance, a detail Onn has not disclosed.
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.
Azo dyes in polyester/nylon fabric
Polyester and nylon textiles, especially in budget-tier black finishes, may contain azo dyes that can release aromatic amines under certain conditions (sweat, friction, heat). Onn does not publish dye sourcing or testing records, so compliance with EU or REACH restrictions cannot be verified.
Formaldehyde / VOCs
Budget polyester and nylon fabrics sometimes use formaldehyde-based resins for wrinkle resistance or dimensional stability during manufacturing. No disclosure from Onn indicates whether this pouch underwent such treatment or whether residual formaldehyde has been removed.
Source, ATSDR ↗Seal and seam degradation over time
Budget-tier sealed-seam pouches from unspecified manufacturers often show premature seam separation after 6-12 months of regular use. Failure compromises the pouch's only waterproofing mechanism and can trap moisture that promotes mold or bacterial growth inside electronics stored within.
PFAS
The waterproof performance of this pouch likely depends on a surface treatment, but Onn does not confirm whether a PFAS-based or non-fluorinated finish was applied. Without disclosure, assume fluorocarbon compounds may be present, which migrate into stored items or seep from seams, particularly in humid or warm conditions.
Source, ATSDR ↗What’s reassuring
Microplastic shedding from fabric
While the pouch itself is not a microplastic generator during normal use (it is not meant to be washed frequently), wear and fraying of the fabric or seams over time could contribute to synthetic fiber release, though minimal compared to textiles worn against skin.
How is this PFAS grade calculated?
The brand's record and disclosure
Onn (Walmart's private electronics and accessories label) maintains no publicly available materials disclosure, PFAS commitment statement, or third-party certifications for this product category. No recalls or safety controversies specific to Onn pouches are on record. The brand's silence on PFAS and fabric treatment chemistry is typical for budget-tier private labels, but it creates uncertainty about whether production meets stricter environmental and health standards or relies on cheaper chemical finishing.
How it compares in its category
Waterproof pouches are a low-risk accessory category overall compared to cookware or cosmetics. Competitors like mainstream outdoor brands (e.g., Sea to Summit, Travelon) typically publish water-repellent treatment details and some offer PFAS-free alternatives. Onn's pouch sits at the budget end with minimal transparency, making direct performance and safety comparison difficult. Most pouches in this price range share similar material compositions but vary widely in whether they disclose finishing chemicals.
If you buy it
Wash the pouch before first use with cool water to remove any loose dyes or finishes. Avoid prolonged contact with skin oils or heat sources, and do not machine-wash or dry-clean, as these can degrade sealed seams and any water-repellent coating. Store dry and unfolded to prevent mildew and creasing that weakens fabric integrity. Inspect seams annually for fraying or separation; replace the pouch if seals fail, as integrity is the only waterproofing guarantee this product offers.
