Gymshark Women's Training Leggings 2.0
Lower concern for standard leggings, but no brand transparency on finishes.
Nylon-polyester-elastane blend with no public disclosure about water-repellent finishes or durable-press treatments that could contain PFAS. Standard athletic wear carries lower risk than explicitly waterproofed garments.

What Gymshark Women's Training Leggings 2.0 is made of, ingredients and materials
Gymshark Training Leggings 2.0 use a nylon and polyester blend with elastane (spandex) for stretch and recovery. Nylon and polyester are synthetic thermoplastics that do not leach BPA or phthalates under normal wearing conditions, unlike some soft plastics used in other apparel. Elastane is chemically stable and not a known source of endocrine disruptors in finished garments. The fiber blend is inherently durable and resistant to degradation from moisture or body heat during typical workouts.
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.
Azo dyes and dye excess
Nylon and polyester are heavily dyed in production. No public dye chemistry disclosure from Gymshark means certain azo dyes (which can release aromatic amines) are not ruled out. Washing before wear reduces loose dyes but does not eliminate baseline exposure.
Formaldehyde / VOCs
Synthetic athletic blends often receive wrinkle-release or anti-microbial finishes containing formaldehyde releasers. Gymshark does not disclose finish composition. Formaldehyde off-gassing is typically low in finished apparel but possible in new garments.
Source, ATSDR ↗Elastane (spandex) degradation and microfiber shedding
Elastane breaks down over time and with repeated washing, releasing microfibers into water and air. This is not brand-specific but inherent to elastane blends. Washing in a mesh bag or specialized filter reduces microfiber release to the environment and clothing.
Heavy metals
Polyester and nylon dyes can contain trace heavy metals (lead, cadmium, chrome) as processing byproducts. Regulation exists in the EU (REACH) but is less strict in other regions where Gymshark manufactures. Skin contact risk is low; GI risk is negligible for apparel.
Source, FDA ↗Antimony in polyester
Polyester production sometimes uses antimony as a catalyst; residual antimony may remain in the fiber. Health risk from wearing apparel is low, but antimony is an irritant at high exposure levels. No specific testing of Gymshark leggings for antimony content is on record.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
How is this PFAS grade calculated?
The brand's record and disclosure
Gymshark has not published detailed material safety certifications or PFAS/chemical finish disclosures for this specific product line as of available public records. The brand does not appear on major chemical transparency initiatives (e.g., Bluesign, OEKO-TEX) for this garment. No product recalls or safety complaints specific to Training Leggings 2.0 are documented. Gymshark's silence on dyes, finishes, and chemical inputs is typical of many athletic apparel brands but limits third-party verification of hazard controls.
How it compares in its category
Nylon/polyester/elastane blends are the industry standard for performance leggings; Training Leggings 2.0 sits in the mainstream middle tier. Brands like Lululemon and Alo Yoga publish more detailed fabric sourcing but rarely disclose dye chemistry; Gymshark is comparable in this regard. Budget alternatives (e.g., Amazon Basics) often use identical fiber blends but with less rigorous QA; premium brands sometimes use recycled nylon or certification logos, which may reduce some chemical exposure but is not a guarantee of full transparency.
If you buy it
Wash in cold water with mild detergent before first wear to reduce loose dyes and finishes. Avoid high-heat drying and direct sunlight for extended periods, as heat accelerates polymer breakdown and elastane loss of stretch. Replace when elastic no longer recovers within 30 seconds of stretching or fabric shows pilling or thin spots. Do not bleach or iron; machine wash on gentle cycle.
