Dive Bomb Waterproof Dry Backpack

F · High PFAS

Waterproof backpack; PFAS status unknown, no brand disclosure.

Verdict: SkipWaterproof backpack with unknown PFAS coating; no brand disclosure on chemical treatment. Non-PFAS hazards minimal if used normally. Monitor for coating degradation.

Garmin's dry backpack uses waterproofing treatment but provides no PFAS information. Coating composition remains unspecified by the brand.

The full breakdown

What it's made of and why it matters

The Dive Bomb uses an unspecified waterproof-treated fabric, likely a polyester or nylon base with a water-repellent coating (water-repellent coating) finish or polyurethane/PVC laminate. The coating's exact chemistry is not disclosed by Garmin, which is common in outdoor gear but prevents verification of treatment type. Waterproof coatings can involve PFAS chemicals (fluorocarbon-based) or non-fluorinated alternatives (polyurethane, silicone). The material composition matters because degrading coatings can potentially leach additives into contents or the environment.

The brand's record and disclosure

Garmin is a navigation and electronics company with limited public statements on PFAS use or elimination in textile products. The brand does not appear to maintain certifications like Bluesign or GOTS that would indicate third-party chemical oversight. No major recalls or safety controversies specific to this backpack have been documented in public records. Garmin's silence on waterproof coating chemistry is typical of the outdoor gear industry but represents a transparency gap for consumers concerned about chemical exposure.

How it compares in its category

Waterproof dry backpacks almost universally use either PFAS-based water-repellent coating or newer non-fluorinated alternatives; Garmin does not market this one as PFAS-free, placing it in the unspecified-treatment category. Competitors like Patagonia and Arc'teryx increasingly disclose PFAS reduction or elimination; most budget and mid-range brands (including Garmin) do not. Among dry backpacks, this is a mid-market product with standard waterproofing but no chemical transparency advantage.

If you buy it

Store the backpack in a cool, dry place away from direct heat or prolonged sunlight, which can accelerate coating breakdown. Avoid machine washing; rinse gently with cool water and air dry. Do not expose the interior or coating to sustained high temperatures (above 60C / 140F). Replace or retire the backpack if the waterproof coating visibly cracks, peels, or loses water-shedding properties, as degraded coatings are more prone to leaching.

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.”

Possible

Coating degradation and leaching potential

Unspecified waterproof coating on textile; long-term durability and leaching behavior of the finish under UV, heat, or wear are not published. Degrading synthetic coatings may release plasticizers or residual monomers, particularly if exposed to heat or prolonged moisture.

None known

Formaldehyde in synthetic textile finishing

No public reports of formaldehyde-based resins in Dive Bomb fabric. Formaldehyde use in polyester or nylon waterproofing is declining but possible in untested products; Garmin provides no test data.

Possible

Azo dyes in colored polyester base

If the backpack base fabric is polyester, synthetic azo dyes may be used for color. Restricted azo dyes (those cleaving to carcinogenic amines) are banned in EU/CA but enforcement in imported goods varies. No Garmin testing or certification addresses this.

Possible

Polyurethane or PVC laminate off-gassing

If the waterproof layer is polyurethane or PVC-based, volatile organic compounds (VOCs) may off-gas during storage or use, particularly in warm conditions. Garmin does not disclose the coating type, so VOC profile cannot be assessed.

Possible

Microplastic shedding from synthetic fibers

Polyester or nylon base fabric may shed microfibers during normal wear and washing. While the dry backpack is not heated or machine-washed frequently, environmental release of synthetic fibers is a class-wide concern in synthetic textiles.

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.
