P-Line CXX X-Tra Strong Moss Green Fishing Line
Lower PFAS concern for fishing line; nylon monofilament typically doesn't require PFAS treatments common in apparel or cookware.
P-Line CXX fishing line is standard monofilament nylon, a material that does not inherently require fluorinated water-repellent or grease-resistant coatings. P-Line makes no public PFAS claims or disclosures.

The full breakdown
What it's made of and why it matters
P-Line CXX is monofilament nylon, a single continuous polymer filament extruded and dyed. Nylon monofilament for fishing does not typically require flame retardant or water-repellent treatments that introduce PFAS or heavy additives. The 'X-Tra Strong' designation refers to tensile strength achieved through polymer formulation and extrusion control, not chemical additives of concern. Moss green color comes from synthetic dyes applied during manufacturing; nylon itself is chemically stable when stored dry.
The brand's record and disclosure
P-Line is a legacy fishing-line manufacturer (Cortland company portfolio) with no public record of chemical disclosure statements or third-party certifications for monofilament products. The brand maintains silent stance on PFAS, which is typical for fishing-line makers because regulatory pressure on this category remains minimal compared to apparel or food-contact plastics. No major recalls or documented safety controversies for standard monofilament products from this brand are available in public records.
How it compares in its category
Monofilament nylon fishing line as a category carries fewer hazard concerns than fluorocarbon alternatives (which may contain PFOA residues from manufacturing) or braided lines (which may accumulate bacterial biofilm if wet-stored). P-Line CXX occupies the mid-to-premium tier of monofilament; it is functionally similar to other major brands (Berkley Trilene, Shimano) in chemical profile. No independent testing distinguishing P-Line's chemical safety from competitors is publicly available, suggesting parity in baseline safety.
If you buy it
Store the spool in a cool, dry place away from direct sunlight to prevent UV degradation and dye fading, which can signal polymer chain breakage. Replace line annually or after heavy use, as nylon absorbs moisture and loses strength over time even if not cast. Wash your hands after handling wet line to remove residual dyes or treatments; do not ingest or allow prolonged skin contact if you have sensitive skin. Dispose of old line in trash or specialized fishing-line recycling programs; do not flush or leave in water bodies.
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.”
Synthetic dyes and color stability
Moss green dye in monofilament is typically azo-based or reactive synthetic dye applied during extrusion. Migration of dye into skin or water is low under normal handling, but sensitivity reactions are theoretically possible with prolonged contact in individuals with dye allergies.
Moisture absorption and microbial growth
Nylon is hygroscopic and absorbs water over time, particularly if stored wet. Prolonged moisture retention can promote bacterial or fungal biofilm on the line, though this is an odor/integrity issue rather than a direct chemical hazard.
UV degradation and polymer breakdown
Nylon monofilament degrades under UV exposure, releasing smaller polymer fragments. This is well-documented in fishing literature and marine science; fragments under 5mm may enter aquatic food chains if line is abandoned in water.
Heavy metals in colorants
Modern monofilament dyes for recreational fishing are not required to disclose heavy metal content (lead, cadmium, chromium). No public testing of P-Line CXX specifically for heavy metal dyes is on record; this represents an information gap rather than a confirmed risk.
Additive leaching into water
While nylon monofilament does not typically contain PFAS or brominated flame retardants, minor UV absorbers or slip agents used in extrusion may slowly leach into freshwater or saltwater under long-term immersion. Concentration is negligible for human consumption risk but may accumulate in closed aquatic systems.
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.
