Womens Outdoor Voices Pants & Jumpsuits Nwt Outdoor Voices Techsweat 7/8 Leggings
Lower concern. Standard activewear fabric without waterproofing.
Outdoor Voices Techsweat leggings are knit polyester blends with no disclosed water-repellent or stain-resistant finishes. Brand makes no PFAS statements; typical performance fabrics present minimal PFAS risk unless water-repellent coating-treated.

What Womens Outdoor Voices Pants Leggings is made of, ingredients and materials
Techsweat is a polyester-blend knit fabric, a synthetic material engineered for moisture management and stretch in athletic wear. Polyester itself is chemically stable during normal wear and washing, but the dyes, finishes, and elastic components used in construction can introduce chemical risks. This particular blend appears to be a standard performance fabric without waterproofing membranes or heavy chemical coatings that elevate hazard profiles.
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 colorant toxicity
Polyester knit fabrics are typically piece-dyed using azo dyes, some of which can release carcinogenic amines under specific conditions. Outdoor Voices does not publicly disclose dye chemistry; standard industry practice does not restrict these dyes in finished garments, but skin contact with untested colorants carries low but non-zero risk, especially in damp conditions or intense sweating.
Antimony in polyester
Polyester production sometimes uses antimony trioxide as a catalyst. While antimony is typically bound in the polymer matrix during normal wear, trace leaching is theoretically possible under acidic or warm conditions. No specific testing for this product is available; risk is generally considered low for non-weathered garments.
Elastane (Spandex) additives and degradation
Leggings rely on elastane fibers for stretch, which may contain flame retardants, UV stabilizers, or antioxidants in the elastomer blend. Outdoor Voices does not disclose elastane sourcing. Degradation from heat, sweat, or repeated washing can theoretically increase leachate; this risk is typical for all synthetic athletic leggings but not quantified for this brand.
Microplastic shedding
All polyester garments shed microplastics during washing. This legging will shed fibers, particularly in the first 5-10 washes and if tumble dried on high heat. Use cold water, air dry when possible, and consider a microfiber capture filter to reduce environmental impact.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Formaldehyde / VOCs
Performance knits occasionally use durable-press or wrinkle-resistant finishes containing formaldehyde-releasing resins. No public evidence suggests Outdoor Voices applies such finishes to Techsweat; a cold rinse on new wear eliminates any residual finish if present.

The brand's record and disclosure
Outdoor Voices is a direct-to-consumer activewear brand without extensive published safety certifications or hazardous-substance disclosures in the public domain. The brand has not faced documented recalls or major chemical controversies as of available records. Material composition transparency is minimal, which is typical for smaller athletic brands but limits independent assessment of dye chemistry and finish treatments.
How it compares in its category
Polyester-blend activewear is mainstream in this category and carries similar chemical profiles to competitors like Lululemon, Athleta, and Girlfriend Collective. Without special water-repellent coatings or exotic finishes, Techsweat sits in the lower-hazard range for synthetic athletic fabrics. The legging format (no heavy dyes, simple construction) is lower-risk than printed or heavily embellished garments.
If you buy it
Wash in cool water and hang dry or tumble dry on low to preserve elastane longevity and avoid heat-induced microplastic shedding. Do not bleach or use fabric softeners, which can degrade polyester and elastic. Replace when elastic loses recovery, seams fray, or fabric pills excessively, typically after 50-100 wash cycles for active wear. New garment off-gassing is minimal with polyester, but a cold rinse before first wear can reduce any residual dyes or finishes.
