Granite Gear Blaze 60 Backpack
Unknown water-repellent coating chemistry; typical outdoor gear risk profile.
Granite Gear does not disclose PFAS avoidance or water-repellent coating chemistry. Most outdoor backpacks use conventional PFAS-based water repellent coatings unless explicitly stated otherwise.

The full breakdown
What it's made of and why it matters
The Blaze 60 uses nylon fabric with a water-repellent coating (water-repellent coating) treatment applied to the surface. water-repellent coating coatings on outdoor gear have historically relied on fluorinated compounds (PFAS), though some brands have shifted to fluorine-free alternatives in recent years. Granite Gear does not publicly disclose which chemistry they use for this pack, leaving the specific PFAS exposure profile unknown. Nylon itself is stable and non-toxic under normal use; the risk centers on the finish treatment rather than the base material.
The brand's record and disclosure
Granite Gear maintains a low public profile on chemical transparency and PFAS stance. No major recalls, certifications (such as BLUESIGN or OEKO-TEX), or third-party testing disclosures are on record for this model. The company does not advertise fluorine-free water-repellent coating or publish material safety data sheets for consumers. This silence does not indicate a problem, but it does mean you cannot verify the water-repellent coating chemistry before purchase.
How it compares in its category
Mid-range backpack tents and packs typically use nylon with water-repellent coating, and Granite Gear is mainstream in this segment. Competitors vary in transparency: some outdoor brands (Patagonia, Arc'teryx, REI Co-op lines) now specify fluorine-free finishes or publish PFAS commitments, while many smaller brands remain silent like Granite Gear. The Blaze 60 is not an outlier in its category, but you have more visibility into alternatives if water-repellent coating chemistry concerns you.
If you buy it
Store the pack dry and away from direct heat or flame; nylon can melt above 160°C (320°F). Reapply water-repellent coating treatments as needed (typically every 1, 2 years after repeated washing) using commercial products or professional service; this maintains water resistance without requiring replacement. Inspect seams and coating for wear annually, especially after heavy use or storage in damp conditions. If concerned about PFAS, contact Granite Gear directly to ask about water-repellent coating composition before purchase.
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
water-repellent coating finishes on nylon naturally degrade with washing and UV exposure. Reapplication involves commercial products that may also contain PFAS or other chemicals, creating a secondary exposure cycle during the pack's life.
Thermal stress on nylon fabric
No defects or melting incidents are reported for the Blaze 60. Nylon is stable under normal outdoor conditions but can soften or shrink if exposed to high heat (>160°C), which would require user error or storage near heat sources.
Seam and adhesive breakdown
Seams and waterproofing adhesives used in construction are not disclosed by Granite Gear. Standard polyurethane or polyester adhesives in outdoor packs are generally recognized as safe once cured, but long-term durability depends on manufacturing quality, which is not independently verified for this model.
Dye stability and heavy metals in dyed nylon
No recalls or contamination reports exist for Granite Gear packs. Nylon dyeing is industrially standardized and does not typically involve problematic heavy metals (lead, cadmium) in mainstream outdoor manufacturers, but the brand does not provide test results.
PFAS in unknown water-repellent coating chemistry
The water-repellent coating treatment chemistry is not disclosed. Conventional fluorinated water-repellent coating (C8 or legacy types) would carry PFAS exposure, while modern fluorine-free water-repellent coating would not. Without specification, typical risk profile for outdoor gear applies: possible but not confirmed.
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.
