Columbia 3 Pc Dry Bag Set - New Sports & outdoors
Skip until Columbia discloses waterproofing chemistry.
Dry bags require water-repellent treatment, likely water-repellent coating. Columbia provides no PFAS disclosure. Unknown coating type poses moderate concern.

The full breakdown
What it's made of and why it matters
Columbia's dry bag set uses nylon fabric with a water-repellent coating. Nylon itself is a stable synthetic polymer with low leaching risk under normal use. The coating is the unknown: it may contain PFAS (PFAS "forever chemicals") to achieve water resistance, or potentially other water-repellent coating (water-repellent coating) treatments like polyurethane or wax-based alternatives. Without Columbia's chemical disclosure, the coating hazard profile cannot be accurately assessed.
The brand's record and disclosure
Columbia Sportswear has not published detailed ingredient disclosures for technical textiles or transparent statements about PFAS use in waterproofing. The brand does not appear on lists of companies committing to PFAS phase-out in outdoor textiles (unlike Patagonia, Arc'teryx, and others who have made public pledges). This silence is the primary safety concern; it prevents informed choice about exposure risk.
How it compares in its category
Dry bags are a commodity product; most budget and mid-tier brands use PFAS-based water-repellent coating coatings because they are durable and inexpensive. Premium brands increasingly offer PFAS-free alternatives using fluorocarbon-free or wax-based coatings, though these may require more frequent reapplication. Columbia's lack of transparency places it in the middle-to-lower tier for precautionary consumer choice, even if the actual chemistry matches competitors.
If you buy it
Store dry bags in cool, dry conditions and avoid prolonged heat exposure (do not wash in hot water or machine dry), as this may accelerate coating degradation and potential leaching. Inspect seams and coating annually for cracks or peeling; replace bags showing significant wear. Hand wash with cool water and mild soap if needed. Do not assume the coating will last indefinitely; nylon-only alternatives without water-repellent coating exist but sacrifice water resistance.
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 (water-repellent coating) coating chemistry - unspecified
The coating composition is not disclosed by Columbia. It may contain PFAS or alternative water-repellent coating agents; without transparency, precaution is warranted. Risk depends entirely on undisclosed chemical identity.
Formaldehyde resins in fabric finishes
Nylon dry bags typically do not require formaldehyde-based finishing agents. No public reports of formaldehyde concerns in Columbia technical textiles of this type. Risk is low but not ruled out without testing.
Azo dyes in colored nylon
Azo dyes (which can break down into banned amines) are restricted in EU textiles but not comprehensively regulated in the US. Columbia does not disclose dye chemistry. Exposure risk is minimal during dry bag use (no skin contact) unless bags are heavily handled or used as food storage.
Coating degradation and microleaching over time
As water-repellent coating coatings degrade with age and washing, particles or residual coating chemicals may leach. Nylon itself is stable, but the coating layer's breakdown products are unknown without ingredient disclosure.
Heavy metals in dyes or colorants
No public recalls or reports of heavy metal contamination in Columbia dry bags. Industrial dye use is generally controlled, but disclosure would strengthen confidence.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 45% 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.

nylon fabric pack, likely uncoated or minimally treated
Food pack likely lower concern; confirm no water-repellent coating with brand.
