YETI Sidekick 3L Dry Gear Case
Unknown water-repellent coating; YETI discloses nothing about PFAS.
This dry gear case uses waterproof-coated fabric, likely treated with water-repellent coating chemicals. YETI provides no public PFAS disclosure or testing data for this product.

The full breakdown
What it's made of and why it matters
The Sidekick 3L uses a fabric base (likely nylon or polyester blend) with a water-repellent coating (water-repellent coating) coating applied to the surface. water-repellent coating coatings shed water but degrade with washing and UV exposure, requiring periodic re-treatment. The specific fluorochemical or non-fluorine formulation YETI uses is not disclosed, making full safety assessment of the coating chemistry impossible.
The brand's record and disclosure
YETI has not publicly released detailed material safety data, PFAS sourcing statements, or third-party certifications for this product line. The company does not appear on lists of brands committing to PFAS-free coatings (such as the Outdoor Industry Association's chemicals management programs). This silence is typical for outdoor gear brands but leaves end-users without transparency on persistent chemical exposure.
How it compares in its category
Soft-sided dry bags in this price range ($60-100) almost universally use fluorinated water-repellent coating coatings because non-fluorine alternatives (wax, silicone, or paraffin) wear out faster and perform poorly in heavy rain. YETI's positioning as a premium brand does not correlate with superior chemical disclosure compared to budget competitors. A small number of brands now offer Teflon-type coating-free or explicitly PFAS-free versions, though performance trade-offs apply.
If you buy it
Avoid machine washing; hand wash only with mild soap and air dry to preserve the water-repellent coating. Do not heat-dry or place near heat sources, as this can degrade the fabric and coating. Expect to reapply a commercial water-repellent coating treatment every 1-2 years depending on use. Monitor the fabric seams and coating for peeling or degradation; replace if structural integrity fails.
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.”
water-repellent coating degradation and reapplication
All water-repellent coating-coated fabrics lose water repellency with use. Reapplication products often contain high PFAS loads, shifting the hazard downstream; this product offers no guidance on low-chemical refresh alternatives.
Azo dyes in synthetic textiles
No specific recalls or warnings exist for YETI fabric dyes. Synthetic dry bags occasionally use azo dyes that release aromatic amines under stress or sweat; YETI does not disclose dye chemistry, but risk is low for external gear bags with minimal skin contact.
Microplastic shedding from synthetic fibers
If the base fabric is polyester or nylon, micro-fibers can shed during use and washing, though this is not unique to YETI and is a known issue across synthetic textiles. Minimal concern for a dry bag used to store gear rather than worn directly on skin.
VOC off-gassing from coating solvents
New water-repellent coating-coated items may release volatile organic compounds for the first few days to weeks. No specific off-gassing data is available for this product; airing out before heavy use or storage in an enclosed space is prudent.
Formaldehyde-based fabric treatments
Formaldehyde resins are rare in dry bags but sometimes used for wrinkle resistance or mildew inhibition in nylon. YETI does not disclose treatment chemistry; testing would be required to confirm absence.
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.
