Yoloha Yoga Balance and Unity Original Cork Yoga Mat
Lower concern; natural materials unlikely to contain PFAS.
Yoloha's cork and rubber yoga mat uses inherently lower-concern materials without applied water-repellent or stain-resistant coatings. No PFAS disclosure found, but material composition suggests minimal PFAS risk.

What Yoloha Yoga Balance and Unity Original is made of, ingredients and materials
This mat combines cork (a harvested tree bark) and natural rubber, both inherently free of synthetic polymer chains that typically carry PFAS or plasticizer concerns. Cork provides grip and cushioning without chemical binders; natural rubber is a latex-derived elastomer that degrades naturally over time, unlike PVC or EVA foams. Neither material requires flame retardant or antimicrobial chemical treatment to meet performance standards. The absence of synthetic coatings or adhesives in this product class is the primary reason hazard exposure is low.
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.
Latex protein allergenicity (natural rubber)
Natural rubber mats may trigger contact dermatitis or respiratory reactions in individuals with documented latex sensitivity, though this is a biological protein response rather than a chemical contamination hazard. Yoloha does not disclose whether latex is thermally treated or protein-extracted.
VOC off-gassing (natural rubber odor)
Natural rubber can emit a characteristic rubbery smell, primarily volatile terpenes, during the first weeks after manufacturing. This is not chemically hazardous but may indicate incomplete curing and should resolve with airing; it is not comparable to toxic isocyanate or phthalate off-gassing from synthetic mats.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Formaldehyde / VOCs
Cork and natural rubber require minimal synthetic glues; no public evidence suggests Yoloha uses formaldehyde-releasing resins in bonding. However, the brand does not provide material safety documentation to confirm adhesive chemistry.
Source, ATSDR ↗Heavy metals
Natural cork and rubber do not require antimony stabilizers or heavy metal pigments. Unless Yoloha adds synthetic dyes or mineral fillers, neither hazard is anticipated; no recalls or testing data contradict this.
Source, FDA ↗Flame retardants
Cork and natural rubber are inherently low-flammability and do not meet flame-spread standards that would mandate brominated or phosphorus-based retardants. No evidence suggests Yoloha applies such coatings to this product.

The brand's record and disclosure
Yoloha does not publicly disclose detailed chemical safety data, certifications (such as GOTS, OEKO-TEX, or Cradle to Cradle), or third-party testing results on their website or in accessible product documentation. No recalls, safety complaints, or established controversies specific to this brand appear in public records. The brand's silence on PFAS and heavy metals is typical for yoga mat manufacturers, but it limits independent verification of manufacturing practices or post-harvest chemical treatments.
How it compares in its category
Natural rubber and cork mats occupy a lower-hazard end of the yoga mat spectrum compared to PVC, EVA, or synthetic foam alternatives, which may contain phthalate plasticizers, flame retardants, or off-gassing VOCs. They avoid the antimony compounds used in some polyester-blended mats. However, natural rubber mats carry a small risk of latex protein allergenicity (not a chemical hazard per se) and may off-gas a faint rubber odor during the first weeks of use. Cork's biodegradability is an environmental advantage but does not reduce chemical risk during use.
If you buy it
Unroll and air the mat outdoors or in a well-ventilated space for 24-48 hours before first use to allow any residual odor from production to dissipate. Store in a cool, dry place away from direct sunlight, which can degrade natural rubber over years. Clean with mild soap and water only; avoid harsh solvents or oil-based cleaners that can soften rubber. Replace when the surface becomes sticky, flakes, or loses grip, typically after 3-5 years depending on frequency of use.
