Alo Yoga Airlift High-Waist Suit Up Legging
Legging fabric likely lower concern; brand silent on PFAS or treatments.
Alo Yoga does not publicly disclose PFAS use or water-repellent coating treatment on this legging. Nylon and spandex are not inherently PFAS-prone, but no third-party verification available.

What Alo Yoga Airlift Suit Up Legging is made of, ingredients and materials
This legging is a nylon and spandex blend, a standard construction for stretchy athletic wear. Nylon is a synthetic polyamide that does not inherently leach heavy metals or BPA; spandex (polyurethane elastomer) provides stretch and recovery without known off-gassing hazards at typical wearing temperatures. The unspecified finish likely refers to moisture-wicking or anti-microbial treatments common to this category, but Alo has not disclosed specific chemical additives, so exact composition remains opaque.
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 colorfast stability
Nylon readily accepts azo-based synthetic dyes, which are not banned but require verification of non-carcinogenic azo compounds. Alo does not disclose dye chemistry, so presence of banned amines cannot be ruled out, though commercial nylon leggings at this price point typically meet US and EU dye safety baselines.
Heavy metals
Dark or vivid-colored nylon leggings may use pigments or dyes containing trace lead, cadmium, or chromium. Alo does not disclose heavy metal testing. Pale or neutral colors statistically carry lower risk, though no guarantee is offered without third-party certification.
Source, FDA ↗Finish chemical off-gassing or skin irritation
Unspecified finishing treatments (moisture-wicking, odor-control, softening agents) may include volatile organic compounds or contact allergens. First wash and ventilation before wear mitigate this risk. No specific adverse events are documented for Alo leggings, but individual sensitivity to undisclosed additives cannot be excluded.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Formaldehyde / VOCs
Nylon-spandex blends do not require formaldehyde-based wrinkle or shape-retention treatments; no record suggests Alo applies such finishes to this product. Cotton-heavy blends carry higher formaldehyde risk, not synthetics like this.
Source, ATSDR ↗Antimony in polyester or polyurethane
Spandex (polyurethane elastomer) does not commonly contain antimony catalysts; antimony risk is primarily in virgin polyester fiber production. This product's nylon warp and spandex content do not trigger known antimony hazard pathways.
How is this PFAS grade calculated?
The brand's record and disclosure
Alo Yoga maintains a wellness-focused brand image but is silent on detailed chemical disclosures, PFAS use, or third-party certifications like Oeko-Tex or Global Organic Textile Standard (GOTS). No major recalls or chemical safety controversies are on public record for Alo apparel. The brand's lack of transparency on dyes, finishes, and treatment chemicals is typical among mid-to-premium athleisure lines but limits independent verification of hazard mitigation.
How it compares in its category
Nylon-spandex blends are the industry standard for high-waist leggings and carry lower chemical risk than cotton-polyester blends treated with formaldehyde resins. Brands with explicit Oeko-Tex certification (e.g., Girlfriend Collective, Patagonia leggings) offer greater transparency, while fast-fashion equivalents may use lower-grade dyes and finishes. Alo's positioning and price point suggest quality construction, but the lack of third-party certification leaves residual hazard uncertainty typical of the premium athleisure segment.
If you buy it
Wash in cool water before first wear to remove any loose dyes or surface residues. Machine wash with mild detergent in warm (not hot) water to preserve spandex elasticity and avoid accelerating any finish degradation. Avoid prolonged direct heat (dryers, radiators) as polyurethane can degrade. Replace when elastic no longer recovers after washing or when fabric pilling or thinning becomes cosmetically unacceptable, typically after 1-2 years of regular use.
