Kelty Asher 24L Backpack
water-repellent coating finish source unknown; Kelty does not disclose PFAS status.
Kelty Asher 24L uses water-repellent coating-treated nylon, a common PFAS application for water resistance. No brand disclosure on PFAS use or avoidance limits confidence.

The full breakdown
What it's made of and why it matters
The Asher 24L uses nylon and polyester fabrics, both synthetic polymers that are chemically stable and not prone to leaching under normal use. The key concern is the water-repellent coating (water-repellent coating) finish applied to the exterior. Historically, water-repellent coating coatings relied on fluorinated compounds (PFAS) to achieve water resistance, though newer non-fluorinated alternatives now exist. Without Kelty's disclosure of which water-repellent coating chemistry is used, the exact composition of this backpack's water-repellent treatment remains unknown.
The brand's record and disclosure
Kelty, owned by Cascade Designs, does not publicly disclose PFAS use or avoidance in its product lineup, nor does the company appear to have committed to PFAS-free standards. This silence is notable because outdoor gear brands have increasingly faced pressure to adopt transparency around water-repellent coating chemistry. No major recalls or chemical safety controversies are on record for Kelty backpacks. The brand's lack of a public PFAS stance makes it difficult for consumers to assess whether this backpack uses legacy fluorinated coatings or newer alternatives.
How it compares in its category
Among mid-range hiking backpacks, the Asher sits in a typical materials profile: nylon/polyester construction is standard and poses no chemical hazards beyond water-repellent coating uncertainty. Some premium competitors (Patagonia, Arc'teryx) now use PFAS-free water-repellent coating or explicitly disclose their choices; others remain silent like Kelty. Budget alternatives using identical or similar materials likely face the same disclosure gap. The Asher's 24L capacity and durability reputation are solid, but environmental and health-conscious buyers may prefer brands with transparent water-repellent coating sourcing.
If you buy it
The backpack requires minimal special handling in normal use. Avoid machine washing at high heat, which could degrade the water-repellent coating finish and potentially increase any coating leachability (though direct skin contact is low with a backpack). Reapply commercial water-repellent coating treatments every 1-2 years if water beading diminishes, and verify the replacement product's composition if PFAS avoidance matters to you. Store in a cool, dry place to extend fabric life; the nylon and polyester themselves will not degrade or offgas under typical conditions.
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 composition (PFAS source unknown)
Kelty does not disclose whether this backpack uses fluorinated (PFAS-based) or non-fluorinated water-repellent coating. Most outdoor gear from this era and price point used PFOA or similar compounds; newer formulations may use shorter-chain PFAS or alternatives. Without confirmation, assume possible PFAS presence.
Formaldehyde in synthetic fiber resins
Nylon and polyester base fabrics do not inherently contain formaldehyde. No reports of formaldehyde-release issues in Kelty backpack products have been documented.
Azo dyes in polyester/nylon fabric
While synthetic textiles can theoretically be dyed with azo dyes that release harmful amines, Kelty's products are not known to have failed azo dye testing, and the backpack's exterior is typically subdued colors unlikely to require high-risk dye chemistry.
Antimony in polyester fiber
Antimony trioxide is used as a polyester catalyst; finished fabrics contain only trace residuals and pose no known risk during normal wear or contact. No concerns have been raised for Kelty backpacks.
Flame retardant treatments
The Asher 24L has no flame-retardant coating on record. Backpack fabrics are not subject to flame-retardant regulations in most markets, and Kelty does not appear to add such treatments to this model.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 42% 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.
