CamelBak Eddy+ Vacuum Insulated SST Bottle
Lower concern; stainless steel core with no reported PFAS treatment, but CamelBak provides no explicit disclosure.
The CamelBak Eddy+ Vacuum Insulated SST bottle's primary material is stainless steel, which does not inherently contain or require PFAS coatings. No public evidence indicates PFAS-based water-repellent treatments on the cap or spout plastics.

Uncoated safe material
Bare, uncoated material (cast iron, stainless, carbon steel, or glass) with no surface treatment to contain PFAS.
The full breakdown
What it's made of and why it matters
The Eddy+ Vacuum Insulated uses double-wall stainless steel (304 or 18/8 grade, industry standard for beverage containers) as the primary wetted surface, which is chemically inert and does not leach metals or breakdown products into liquids. The spout and cap are plastic polymers, typically polypropylene (PP) or similar food-contact plastics; because they are not immersed constantly and handle liquid at ambient-to-warm temperatures (not boiling), leaching risk from these components is minimal. The vacuum seal between walls contains air and sometimes a small amount of mineral insulation; this sealed space poses no direct consumer contact hazard.
The brand's record and disclosure
CamelBak does not publicly disclose PFAS testing or intentional PFAS-free certification for this model, though stainless steel bottles are inherently unlikely to be treated with PFAS coatings. The brand has no documented safety recalls specific to the Eddy+ line related to material leaching or contamination as of public record. CamelBak markets the product as food-safe and suitable for hot and cold beverages but does not provide third-party material certifications (e.g., NSF, FDA compliance statements beyond baseline) on product pages.
How it compares in its category
Water bottles in the insulated stainless steel category are generally the lowest-risk beverage containers because the core material is passive and non-leaching. The Eddy+ is positioned as a mainstream consumer product, not a clinical or premium certifications-backed option; comparable brands (Hydro Flask, S'well, Klean Kanteen) similarly avoid explicit PFAS disclosure but share the same material safety profile. Plastic-bodied or plastic-lined alternatives carry higher leaching potential if heated or aged; the Eddy+ avoids that.
If you buy it
Hand-wash the spout and cap in cool to warm water; do not expose to prolonged boiling or dishwasher cycles, as repeated thermal stress can degrade plastic components and may cause micro-delamination of seals. Do not store acidic beverages (lemon water, vinegar) for weeks at a time, as prolonged contact with weak acids can slightly accelerate surface micro-corrosion on stainless steel (rare but possible). Replace the spout gasket or cap if you notice discoloration, odor, or visible wear; these are typically available as replacements. Rinse interior after each use and allow to air-dry fully if storing empty for extended periods to prevent any mineral or mold buildup inside the sealed void.
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.”
Plastic spout/cap degradation over time
Repeated thermal cycling (hot fill, cold storage) and UV exposure can cause polypropylene spout and cap to become brittle, discolored, or develop micro-cracks, potentially releasing small plastic particles. No documented recalls for this model, but typical for multi-year use in this product category.
Stainless steel surface corrosion (acidic beverage contact)
While 304 stainless is highly corrosion-resistant, prolonged storage of acidic liquids (citrus, vinegar, kombucha) may cause pitting or white surface oxidation over months. This is aesthetic and does not typically produce hazardous leaching, but indicates material stress.
Vacuum seal degradation and moisture ingress
The double-wall vacuum seal is a structural weak point; impact or manufacturing defect can compromise insulation and introduce moisture or microbes into the sealed airspace. CamelBak does not publish seal failure rates; anecdotal reports exist but are not systematic recall data.
Bacterial or mold growth in spout valve mechanism
The Eddy+ spout includes a flip-cap and valve; if not thoroughly cleaned between uses or left damp, the plastic valve seats and internal passages can harbor biofilm or mold, particularly in warm climates. Regular disassembly and drying mitigates this; manufacturer instructions should be reviewed.
Leaching from plastic cap gaskets or seals
No reported instances of off-odors, off-taste, or chemical leaching from the spout gaskets on the Eddy+ line in public data. Gasket material is typically EPDM or silicone, both low-leach; however, aging and heat exposure are not independently tested by the brand.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
