The full breakdown
What it's made of and why it matters
The Everdry Dry Bag is constructed from nylon fabric with an unspecified waterproof coating. Nylon itself is a durable, inert synthetic polymer with no known leaching hazards under normal use. The coating chemistry is the critical unknown: waterproofing on dry bags is typically achieved via Teflon-type coating (Teflon), polyurethane, or water-repellent coating (water-repellent coating) treatments, and some formulations historically relied on fluorinated compounds to achieve performance. Without manufacturer disclosure, the coating composition cannot be assessed for PFAS or other coating-specific risks.
The brand's record and disclosure
ALPS Mountaineering does not publicly disclose waterproof coating chemistry, PFAS testing, or toxicology for this product. No third-party certifications (such as bluesign, OEKO-TEX, or GOTS) are listed on the product. The brand maintains no visible position on PFAS avoidance or material transparency in outdoor gear, which is standard practice for many competitors in the dry bag market.
How it compares in its category
Dry bags are a low-risk product category for dermal or ingestion exposure because they contact gear, not skin or food directly. However, they do contact water and wet items; if the waterproof coating sheds microparticles or leaches chemicals into stored water, exposure is possible. Competitor brands like Sea to Summit and Patagonia increasingly disclose coating materials or pursue PFAS-free formulations, making the Everdry's silence on this issue a relative weakness in transparency, though not uncommon.
If you buy it
Store dry bags away from direct sunlight and heat to minimize coating breakdown. Rinse the bag occasionally with fresh water and allow it to air-dry completely before sealing to prevent bacterial or mold growth inside, which is unrelated to the coating but a standard maintenance step. Do not heat-seal or expose to high temperatures, as this could stress the waterproof layer. If you have concerns about PFAS, contact the manufacturer to request coating composition; absence of a response suggests the coating is not PFAS-screened.
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.”
Waterproof coating composition (PFAS and alternatives)
The specific waterproof coating is not disclosed by the manufacturer. Historically, many nylon dry bags have used fluorinated water-repellent coating treatments or Teflon-type coating, which may contain PFAS or legacy PFAS-adjacent chemistries. Without testing or disclosure, risk cannot be quantified but should be assumed possible.
Coating degradation and microparticle shedding
No documented cases of Everdry bags shedding coating particles or leaching chemicals into stored contents exist in public records. Nylon dry bags are designed for durability and do not typically delaminate or shed under normal freshwater storage use.
Formaldehyde or azo dyes in nylon fabric
Nylon fabric used in outdoor gear is rarely finished with formaldehyde resins or hazardous azo dyes due to durability and regulatory exposure. ALPS Mountaineering products do not carry reports of formaldehyde or azo dye contamination.
Heavy metals in pigments or dyes
No known incidents of cadmium, lead, or other heavy metals in Everdry dry bag coloration. Outdoor gear manufacturers typically use color-fastness standards that exclude these metals, though no third-party verification is listed for this brand.
Bacterial or mold growth if improperly maintained
If the bag is sealed while damp or stored in humid conditions, internal microbial growth is possible. This is a use-and-maintenance issue, not a material hazard, but relevant to safe product function.
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.
