Under Armour Men's Fish Pro 2.0 Cargo Shorts

F · High PFAS

Fishing shorts likely have water-repellent coating treatment; PFAS risk unclear without disclosure.

Verdict: SkipPolyester cargo shorts with water-repellent coating finish carry unclear PFAS risk and standard synthetic dye hazards; manageable with informed care and awareness of water-resistance treatment unknowns.

Pro fishing shorts typically use water-repellent coating finishes, which commonly contain PFAS. Under Armour provides no public PFAS statement for this product, leaving exposure uncertain.

The full breakdown

What it's made of and why it matters

These shorts are polyester blend, likely 88% polyester/12% spandex or similar elastane content based on typical Under Armour construction. The water-repellent coating (water-repellent coating) finish is the primary concern: manufacturers often use PFAS-based treatments to achieve water-resistance, though some now use PFAS-free alternatives. The polyester itself is synthetic polymer stable under normal wear; the finish treatment applied post-manufacture is where chemical leaching risk concentrates, especially if the coating degrades from washing, sun exposure, or abrasion.

The brand's record and disclosure

Under Armour has not published detailed water-repellent coating chemistry or PFAS phase-out commitments specific to their apparel lines, placing them behind outdoor brands like Patagonia or The North Face on transparency. The company remains silent on whether this product uses legacy fluorinated compounds or newer fluorine-free alternatives. No major recalls or PFAS-specific controversies have been documented for Under Armour shorts, but lack of disclosure is itself a red flag for informed consumers seeking chemical specificity.

How it compares in its category

Most budget to mid-range fishing and performance shorts with water-repellent coating finishes carry similar undisclosed PFAS risk. High-end alternatives (Simms, Orvis) increasingly disclose PFAS-free treatments, while budget alternatives often use spray-on fluorinated coatings. Under Armour sits in the middle market where water-repellent coating is standard but transparency is rare. If PFAS avoidance is a priority, seeking brands with explicit PFAS-free certifications (Bluesign or similar) would reduce this uncertainty.

If you buy it

Wash in cool water and avoid hot machine drying, which can accelerate coating breakdown and any potential leaching from the water-repellent coating finish. Air-dry flat or hung to extend the water-resistant layer's life. Replace after 2-3 years of regular use or once water-repellency visibly fails (beading stops). Do not dry-clean or iron, as heat and solvents degrade synthetic coatings. If PFAS exposure concerns you, consider these shorts acceptable for activities where the water-repellent coating is not essential (casual wear) rather than frequent water exposure.

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.”

Possible

Azo dyes in polyester coloring

Polyester fishing shorts often use acid or disperse dyes; not all are azo-free, and no manufacturer testing is publicly available for this specific product. Risk of allergic skin reactions or dye migration is low but increases with prolonged moisture and heat.

Possible

water-repellent coating degradation and leaching

The water-resistant finish degrades over time and washing; if PFAS-based, leaching into sweat or wash water is greatest during early use and after the coating begins to fail. Under Armour's silence on chemistry makes risk quantification impossible.

None known

Spandex elastane thermal instability

Spandex blends in shorts are stable under normal wear and modest heat; no documented hazard for this product type or brand. Avoid prolonged direct sunlight or machine drying on high heat to preserve elasticity and avoid any theoretical volatile release.

None known

Formaldehyde resins in finishing

Modern polyester apparel finishes typically avoid formaldehyde resins, and no recalls or testing for this product suggest active contamination. water-repellent coating treatment is the primary post-manufacture chemical, not formaldehyde-based.

Possible

Synthetic fiber microplastic shedding

All polyester apparel sheds microfibers during washing; water-repellent coating-coated items may shed slightly more as the coating degrades. This is a water-quality concern rather than direct wearer hazard but relevant for environmental context.

What we don’t know

This grade is a model-based estimate from public materials, coatings, and brand disclosure at 48% 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.
