Alo Yoga Pants & Jumpsuits Alo 7/8 High Waist Airlift Leggings
Low PFAS risk; typical activewear without known water-repellent coating finish.
Alo Yoga leggings are nylon/spandex blend with no disclosed water-resistant or stain-resistant finish. No PFAS claims or third-party verification available, but standard activewear without water-repellent coating treatment carries lower concern.

What Alo Yoga Pants Airlift Leggings is made of, ingredients and materials
This legging is a nylon and spandex (elastane) blend, the industry standard for high-stretch activewear. Nylon provides durability and moisture-wicking; spandex adds recovery and shape retention. This material combination does not inherently require chemical finishes to perform, though dyes and processing agents are applied during manufacturing. The 7/8 length and high-waist cut do not introduce additional coating or treatment concerns beyond standard dyeing.
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.
Formaldehyde / VOCs
Nylon and spandex activewear are routinely dyed with acid and reactive dyes; use of restricted azo dyes or formaldehyde-releasing finishes is not reported for Alo Yoga specifically, but no independent certification is publicly available to rule it out.
Source, ATSDR ↗Dye migration and skin contact irritation
Dark-colored nylon leggings may release dyes in early washes; this is common across the category and not unique to Alo. Dermatitis risk is low but present in first few wears, especially for sensitive skin.
Spandex degradation and microfiber shedding
All spandex-blended garments degrade with heat and repeated washing, releasing microfibers into water and air. Alo's product design does not mitigate this; this is inherent to the material class and not a brand-specific concern.
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 reports of heavy metal contamination in Alo leggings; modern nylon dyeing typically does not introduce cadmium or lead, but third-party testing is not publicly available.
Source, FDA ↗Flame retardants
Nylon/spandex activewear is not a sleepwear or upholstery product and is not subject to flame retardant regulations; no flame retardants are reported in this product category.

The brand's record and disclosure
Alo Yoga has not publicly released detailed chemical composition or supply-chain transparency reports; PFAS disclosure is absent from available brand communications. The company has not faced documented recalls or safety violations specific to chemical hazards in their core apparel line. Without third-party certification (e.g., OEKO-TEX, GOTS) on this product, formaldehyde resin use in finish or azo dye safety cannot be independently verified through public sources.
How it compares in its category
Alo Yoga occupies the premium activewear segment; competitors in that range (Lululemon, Outdoor Voices, Girlfriend Collective) similarly lack systematic chemical disclosure but do not face established hazard alerts for standard nylon/spandex leggings. Most brands in this category use conventional reactive or acid dyes without reported carcinogenic azo dyes, though this is not confirmed for Alo specifically. Low PFAS risk aligns with the category trend away from water-repellent coating finishes in stretch fabrics.
If you buy it
Wash in cool water (below 30°C/86°F) and air dry to preserve spandex elasticity and minimize dye bleeding. Do not expose to direct heat (dryer, iron) as high temperatures degrade spandex permanently. Replace when waistband loses shape, seams fray, or pilling becomes excessive (typically 1, 2 years of regular wear). If skin irritation develops after first few wears, rinse thoroughly before next use to remove residual dyes or finishes.
