Alo Yoga High Waist Airbrush Leggings Women's
Skip unless Alo discloses water-repellent coating treatment or certifies PFAS-free.
Alo Yoga does not publicly disclose PFAS risk or water-repellent coating finishes on this legging. High-waist athletic leggings often receive water-resistant treatments that may contain PFAS, but Alo's silence prevents assessment.

What Alo Yoga High Waist Leggings Women's is made of, ingredients and materials
Alo's Airbrush leggings are nylon-spandex (elastane), a synthetic blend chosen for stretch, durability, and moisture-wicking. Nylon itself does not leach toxic monomers into skin under normal wear. Spandex adds elasticity but degrades over time with heat, washing, and UV exposure, eventually losing shape and support. Neither material is known to off-gas volatile organic compounds (VOCs) in the way some foams or adhesives do.
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.
Spandex degradation and fiber shedding over time
Elastane in all performance leggings breaks down with repeated washing, heat, and UV exposure, eventually shedding microfibers. This is a material-class limitation, not unique to Alo, and occurs faster with hot water or machine drying.
PFAS
PFAS grade is 65/100 (Good) and Alo's stance is silent; if Airbrush leggings carry a water-repellent finish, PFAS may be present but is not confirmed by the brand. See PFAS assessment separately.
Source, ATSDR ↗What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Heavy metals
No recalls or test reports document azo dyes or heavy metal pigments in Alo Yoga apparel. Industry standard dyeing for nylon-spandex does not inherently require restricted azo compounds, but Alo does not publish dye certifications, so independent verification is unavailable.
Source, FDA ↗Formaldehyde / VOCs
Nylon-spandex blends do not typically require formaldehyde-based finishing resins; such treatments are more common in cotton blends for wrinkle resistance. No public record links Alo leggings to formaldehyde residues.
Source, ATSDR ↗Allergens in fragrance or dyes (skin contact irritation)
No established allergen warnings or complaints specific to Alo leggings. Individuals with sensitive skin should test a small area or review ingredient lists if a scent finish is applied, though none is documented for this product.
How is this PFAS grade calculated?
The brand's record and disclosure
Alo Yoga does not publicly disclose fabric treatment details, dye processes, or chemical certifications (such as OEKO-TEX or bluesign). The brand has not faced documented recalls or regulatory action for formaldehyde, azo dyes, or heavy metal contamination in textiles. However, silence on water-repellent or antimicrobial finishes is notable; if the Airbrush line uses a water-repellent coating (water-repellent coating) coating, PFAS presence is possible but unconfirmed by independent testing.
How it compares in its category
Performance leggings in this price tier typically use similar nylon-spandex blends. Alo's design and finish are mainstream; no evidence suggests this product is chemically safer or riskier than competitors like Lululemon, Outdoor Voices, or Athleta in the same material class. Alo does not publish third-party certifications, placing it in the middle of the transparency spectrum for premium activewear.
If you buy it
Wash in cold water and air-dry to slow spandex degradation and prevent potential azo dye migration at high temperatures. Avoid bleach and direct sunlight for prolonged periods. Replace leggings when waistband or seams show permanent stretching, as compromised elastane can no longer support its intended function. Do not machine-dry, as heat accelerates fiber breakdown.
