Compressive High-Rise Legging
Lower concern; untreated nylon/spandex has no known PFAS risk.
Girlfriend Collective does not disclose PFAS treatment on this legging. Compressive nylon/spandex blends typically have lower PFAS concern than coated or waterproofed fabrics, but brand transparency is absent.

What Compressive High-Rise Legging is made of, ingredients and materials
This legging is a nylon and spandex (elastane) blend, a standard synthetic textile base for compression wear. Nylon itself is an inert plastic polymer with minimal leaching risk in normal wear. Spandex provides stretch and recovery but is not a known source of regulated contaminants when used as a fiber. The lack of any disclosed coating (water-repellent, antimicrobial, or performance finish) means no additional chemical treatments are present to degrade or migrate during use.
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.
Heavy metals
Dye composition for the legging is not disclosed. Nylon accepts both azo and non-azo dyes; without independent testing or material certification (Oeko-Tex), presence of regulated azo dyes or heavy metal contaminants in the dye cannot be ruled out, though no incidents are on record for this brand.
Source, FDA ↗Microplastics
All synthetic textile fibers, including nylon and spandex, shed microfibers during laundering. Spandex degrades faster with heat and mechanical stress, increasing shedding over time. Cold washing and air drying reduce (but do not eliminate) this release.
Source, EPA ↗What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Formaldehyde / VOCs
No finishing treatment is disclosed for this product. Untreated nylon/spandex blends do not use formaldehyde-based wrinkle-resist or water-repellent resins.
Source, ATSDR ↗Antimony in polyester fiber (cross-check)
This product is nylon/spandex, not polyester. Antimony trioxide, used as a catalyst in polyester synthesis, is not relevant here.
Fragrance allergens or skin irritation
No fragrance or fragrance-containing finishes are disclosed on this product. Risk is negligible unless residual detergent or fabric softener is retained after washing.
How is this PFAS grade calculated?
The brand's record and disclosure
Girlfriend Collective does not publicly disclose material certifications (Oeko-Tex, GOTS, or bluesign) or detailed chemical testing results. The brand has not issued recalls or safety advisories specific to this product line as of available records. Their silence on PFAS stance is typical for apparel brands; absence of a water-repellent or stain-resistant finish claim on this product makes intentional PFAS use unlikely, though third-party verification is not available.
How it compares in its category
Compression leggings typically use the same nylon/spandex matrix. This product avoids common hazard sources like flame-retardant coatings (not needed in apparel) and antimicrobial finishes that can shed microplastics or introduce heavy metals. Compared to leggings with applied water-resistant or performance coatings, the absence of such treatments here reduces risk of unknown migrating compounds, though it also means no stain resistance benefit.
If you buy it
Wash in cool water with mild detergent; hot water can degrade spandex elasticity faster. Avoid fabric softeners and high heat drying, which accelerate fiber breakdown and microfiber shedding. Expect replacement every 18-24 months with regular wear, as spandex loses recovery capacity over time. Air dry when possible to extend lifespan and reduce microfiber release into washing machine effluent.
