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
Leather and synthetic textiles sometimes use formaldehyde-releasing finishes to improve water resistance and durability. Mizuno does not publish safety data sheets for the Comp Glove. Formaldehyde off-gassing from external athletic gear is negligible compared to indoor upholstery or textiles, and airing the gloves before first use reduces any volatile exposure.
Source, ATSDR ↗Microbe growth if left damp
Synthetic leather and foam padding trap moisture and can harbor bacteria or mold if stored wet. This is a maintenance issue rather than manufacturing hazard. Regular drying and ventilation eliminate this risk entirely.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Lead
Synthetic leather overlays in the Comp Glove reduce this risk compared to all-leather gloves. No recalls or testing results document metal leaching from Mizuno's glove production. Chrome tanning salts are industry-standard but external hand contact poses minimal absorption risk.
Source, ATSDR ↗Phthalates
No test data or regulatory action against this product exists. Mizuno does not disclose adhesive or plasticizer chemistry, but modern athletic glove manufacturers have largely shifted to phthalate-free formulations due to market pressure. Synthetic leather grades vary; exposure risk is minimal because use is external and non-oral.
Source, ATSDR ↗Azo dyes in leather colorants
Restricted azo dyes (those releasing carcinogenic amines) are banned in EU textiles and cosmetics but less regulated in sporting goods. No recall or test data implicates Mizuno's Comp Glove. External contact and lack of oral/ingestion risk make this a very low hazard even if present.
The full breakdown
What it's made of and why it matters
The Mizuno Comp Glove combines leather (typically cowhide) with synthetic leather overlays in high-wear zones. Synthetic leather in athletic gloves is usually polyurethane or PVC-based, chosen for durability and water resistance. The blend approach reduces reliance on chrome tanning (a lead/cadmium contamination risk in all-leather gloves) while maintaining grip and breathability. Modern athletic glove construction avoids adhesives with high phthalate content, though formulations vary by supplier.
The brand's record and disclosure
Mizuno is a established Japanese sportswear manufacturer with no public chemical safety controversies on record for its gloves. The brand does not disclose leather tanning methods, dye sources, or adhesive chemistries for this product line, which is typical of athletic equipment makers and not a red flag unique to Mizuno. No recalls or safety warnings involving the Comp Glove have been documented. Mizuno holds no major certifications (e.g., Bluesign, OEKO-TEX) for this category, reflecting broader industry practice for non-clothing athletic gear.
How it compares in its category
Athletic gloves occupy a low-hazard segment compared to cookware or cosmetics because contact is external and brief. The Comp Glove's synthetic-leather hybrid presents lower concern for heavy-metal leaching than all-chrome-tanned leather and lower concern for plasticizer migration than cheap all-PVC construction. Premium alternatives (e.g., leather-only brands) may use vegetable tanning to avoid chrome but offer no additional chemical safety benefit. Budget synthetic-only gloves carry higher phthalate risk due to cost-cutting on adhesives and coatings.
If you buy it
Wash gloves with cool water and mild soap after use to remove sweat and dirt; heat (e.g., machine wash, dryer) may degrade synthetic components and adhesives over time. Store in a dry place away from direct sunlight to prevent polyurethane breakdown. Replace when seams separate, synthetic overlays crack, or grip deteriorates, typically after 1-3 years of regular use. No special care is needed beyond standard athletic gear maintenance; the product is not designed for food contact or oral use.
