Topo Designs Classic Teardrop Backpack
Lower PFAS concern; conventional backpack materials without waterproofing trigger.
The Topo Designs Classic Teardrop Backpack uses untreated ballistic nylon and canvas, materials not inherently linked to PFAS. Topo Designs makes no PFAS claims and publicly emphasizes durability over water-resistance, suggesting no water-repellent coating.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
