Spiderwire Stealth Smooth

Good

Skip until clarity; fishing line coatings are often proprietary and undisclosed.

Verdict · SkipBraided PE fishing line with undisclosed coating; no established hazards beyond PFAS uncertainty. Use with standard precautions; avoid ingestion/skin contact with coating.

This braided line uses a smooth proprietary coating designed to reduce friction, but SpiderWire provides no PFAS or composition details. Fishing tackle coatings remain largely undisclosed.

What Spiderwire Stealth Smooth is made of, ingredients and materials

Spiderwire Stealth Smooth is braided polyethylene (PE) with a proprietary outer coating claimed to reduce visibility and improve casting. Braided PE itself is a stable, inert plastic under normal fishing conditions. The coating's exact chemistry is not publicly disclosed by the manufacturer, which means potential additives like UV stabilizers, colorants, or slip agents cannot be independently verified. This opacity is the primary concern, as fishing line coatings sometimes contain or leach compounds during use.

Coating leachates (undisclosed composition)

The proprietary coating is not publicly disclosed; unknown additives could leach into water or skin during use, though no documented incidents are on record for this product.

Microplastic fragmentation

Braided PE breaks down over time, especially under UV and mechanical stress. Fragments entering waterways are a known concern for all synthetic fishing lines, not specific to this brand but relevant to use context.

What’s reassuring

✅

Colorant stability and migration

No evidence of dye instability or heavy metal pigments in Spiderwire products; however, the specific colorants in Stealth Smooth are not disclosed and cannot be independently verified.

95/ 100
⛏️

Heavy metals

No recalls or test results indicate lead, cadmium, or other heavy metals in this product; braided PE coatings typically use lighter additives, but lack of disclosure prevents absolute exclusion.

✅

Skin irritation or sensitization from coating contact

No reported cases of dermatitis or allergic reaction attributed to Stealth Smooth handling; risk is low but depends on individual sensitivity and coating formulation clarity.

How is this PFAS grade calculated?

The brand's record and disclosure

Spiderwire (owned by Pure Fishing/Newell Brands) does not publish detailed material safety data sheets or coating composition for this product line. The brand has no published certifications regarding contaminant limits or independent testing for leachates. No product recalls or safety alerts are on record for Stealth Smooth. The lack of transparency about the coating formulation is consistent with industry practice but limits third-party verification of safety claims.

How it compares in its category

Most braided fishing lines use similar undisclosed coatings; monofilament alternatives (nylon) have simpler chemistry but different performance traits. Spiderwire is a market leader with decades of use history, which provides some indirect safety reassurance via absence of documented harm. However, newer or niche brands sometimes offer greater transparency about coating materials. Among braided lines, Stealth Smooth occupies a mid-to-premium tier where coating durability and performance claims exceed safety documentation.

If you buy it

Rinse hands after handling, especially if the coating flakes or degrades visibly over time. Do not allow children to chew on or ingest line fragments. Store in a cool, dry place away from direct sunlight to minimize coating breakdown. Replace if the outer coating shows significant peeling, discoloration, or loss of smoothness, as this may indicate material degradation and potential leachate risk during use.
