ALPS Mountaineering Everdry Dry Storage Pack
Waterproof pack with unspecified coating; PFAS risk unclear
ALPS Mountaineering does not disclose PFAS or water-repellent coating chemistry for this dry bag. Waterproof coatings often use PFAS; without transparency or testing, risk cannot be ruled out.

The full breakdown
What it's made of and why it matters
The Everdry pack uses nylon or polyester (exact fiber not specified by ALPS) with a water-repellent coating (water-repellent coating) coating applied to the exterior. water-repellent coating coatings historically relied on PFAS-based chemistry to achieve water shedding, though some manufacturers have transitioned to PFAS-free alternatives. Since ALPS does not publicly disclose the coating chemistry, you cannot confirm whether this pack contains legacy PFAS or newer PFAS-free formulations. The base nylon or polyester itself carries minimal direct toxicity risk under normal storage and handling conditions.
The brand's record and disclosure
ALPS Mountaineering does not publicly commit to PFAS-free materials or provide transparency on water-repellent coating chemistry in product lines. The brand has no widely documented sustainability certifications (Bluesign, GOTS, or equivalent) that would signal third-party scrutiny of coating inputs. Outdoor gear brands vary widely in this disclosure; ALPS remains in the middle-to-silent tier, neither known for controversy nor for leadership on chemical transparency. Without direct contact, you cannot definitively rule out PFAS in this product.
How it compares in its category
Dry storage packs from outdoor brands typically use nylon or polyester with water-repellent coating coatings, placing the Everdry in the standard mainstream tier. Premium competitors (e.g., Patagonia, Arc'teryx) often disclose PFAS-free or certified coatings; budget/mid-tier brands like ALPS typically do not. The Everdry's lack of transparency is common but not exceptional; many entry-level outdoor storage products share this gap. If PFAS avoidance is a priority, brands with explicit PFAS-free claims offer clearer assurance.
If you buy it
Wash the pack with cool water before first use to reduce any loose coating residues or off-gassing compounds. Avoid prolonged heat exposure (direct sunlight for extended periods, car heat) as elevated temperatures can accelerate degradation of water-repellent coating coatings and potential leaching. Store dry; moisture trapped inside can degrade seams and create odor. Replace the pack if the water-repellent coating visibly delaminates or loses water-shedding capacity, which typically occurs after 3-7 years of outdoor use depending on UV and mechanical stress.
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 leaching
Unspecified water-repellent coating formulation may degrade under UV, heat, or mechanical wear, potentially releasing coating particles or residual monomers. Risk is low under normal storage but increases with age and environmental stress.
Formaldehyde resins in polyester or nylon finishes
ALPS does not document use of formaldehyde-based cross-linking resins in the Everdry. Nylon and polyester base fibers themselves do not inherently contain formaldehyde, though finishing treatments may. No recalls or complaints on record for off-gassing.
Azo dyes in synthetic fiber colorants
If the pack is dyed (dark colors typical), synthetic dyes including azo compounds may be present; standard industry practice for budget-tier outdoor nylon. Direct skin contact is minimal for a dry bag, but potential exposure via handling or washing exists. Not specific to ALPS; typical of the material class.
Antimony catalyst residues in polyester
If the pack is polyester-based, antimony oxide may be used as a catalyst during fiber production. Residual antimony in polyester is typically very low and migrates negligibly under normal use. Risk is theoretical unless the product is chewed or heated extensively.
Microplastics shedding during washing or abrasion
Nylon and polyester shed microfibers when washed or abraded (e.g., friction in a backpack). A dry storage pack sheds minimal fiber during normal use because it is not next to skin and experiences less mechanical stress than apparel. Washing should be infrequent and gentle to minimize shedding.
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.
