RLX Ralph Lauren Men's Stretch-Nylon Pants
Nylon pants with stretch likely treated for water resistance; PFAS risk unclear.
Stretch nylon typically uses water-repellent coating finishes that may contain PFAS. Ralph Lauren provides no PFAS disclosure.

What RLX Ralph Lauren Men's Stretch-Nylon Pants is made of, ingredients and materials
RLX Ralph Lauren stretch-nylon pants are constructed from nylon 6 or nylon 66 blended with elastane (spandex) for stretch recovery. The 'wrinkle-free' and water-resistant (water-repellent coating) finish almost certainly involves fluorinated compounds or other water-repellent coating treatments applied to the fabric surface. Nylon itself is a stable synthetic polymer with low chemical leaching risk during normal wear, but the water-repellent coating and any finishing resins are the primary chemical concern in this product category.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
water-repellent coating (water-repellent coating) fluorinated compounds
Standard nylon workwear finishes often use C6 or C8 fluorocarbons. RLX does not disclose which water-repellent coating chemistry is used; some fluorinated finishes are restricted in the EU but still legal in the US. Skin contact risk during wear is minimal; primary concern is laundry water contamination and bioaccumulation if compounded over many garments.
Formaldehyde / VOCs
Wrinkle-free and shape-retention treatments on nylon can involve formaldehyde-based resins. RLX does not specify its finishing chemistry. Off-gassing is minimal at room temperature but may increase slightly in warm, humid conditions; proper first washing reduces any residual exposure.
Source, ATSDR ↗Microplastic shedding
Synthetic nylon textiles shed microfibers in the wash. RLX pants will contribute to this; use a microfiber-catching laundry bag or filter to reduce environmental release. This is a laundering practice issue, not unique to this brand.
What’s reassuring
Azo dyes and colorant safety
No specific azo dye or heavy metal contamination has been reported in RLX nylon pants. Premium nylon apparel typically uses quality commercial dyes, but without OEKO-TEX or similar certification, individual batch testing is not transparent.
Elastane (spandex) and polyurethane stability
Elastane blends in nylon stretch pants are chemically stable during normal wear and washing. Degradation occurs over 3-5 years, leading to loss of stretch rather than chemical leaching; this is a performance issue, not a safety hazard.
How is this PFAS grade calculated?
The brand's record and disclosure
Polo Ralph Lauren has not made public commitments to phase out PFAS in apparel or published detailed material safety data sheets for individual garments. The brand maintains general sustainability messaging but has not disclosed specific testing results, certifications (such as OEKO-TEX), or restrictions on fluorinated water repellents. No major chemical contamination recalls have been issued for RLX pants, but the lack of transparency makes it difficult to assess compliance with emerging PFAS restrictions in Europe and some US states.
How it compares in its category
Professional wrinkle-free nylon pants routinely use water-repellent coating finishes; RLX sits at the premium end but does not differentiate on chemical safety. Competitors like Banana Republic and J.Crew rarely disclose water-repellent coating chemistry either. Brands certified to OEKO-TEX Standard 100 or using water repellents not linked to PFAS (such as polyurethane or wax-based alternatives) present lower concern in this category, though they are less common and often cost more.
If you buy it
Wash separately in cold water the first two to three times to minimize any loose finish transfer. Avoid high heat drying; air dry or use low heat to preserve the water-repellent coating and elastane stretch. The water-resistant finish will degrade over 50-100 washes; replacement is normal and signals you have used the garment fully. Do not use fabric softeners or bleach, as these can strip the finish and prompt re-treatment with uncertain chemicals.
